1. Overview

Jesse Livermore wrote How to Trade in Stocks in 1940 as the direct, first-person presentation of his trading methodology. Unlike Edwin Lefevre's fictionalized Reminiscences of a Stock Operator (1923), this book is Livermore's own systematic treatise — a technical manual for speculation.

The book's central contribution is the Livermore Market Key, a proprietary price-recording and trend-identification system that Livermore developed over his decades of trading. The Key is not a formula or indicator in the modern sense; it is a manual state machine — a structured bookkeeping method that forces the trader to classify every significant price move into one of six defined states, and to act only when the transitions between those states confirm a tradeable trend.

Core Thesis: Speculation is a business, not a gamble. It requires:

• A defined method for reading the tape (the Market Key)
• Patience to wait for the correct moment (the Time Element)
• Recognition of critical turning points (Pivot Points)
• Strict capital preservation rules (Money Management)
• Emotional self-mastery (Discipline)

Livermore insists that no one can consistently profit by trading every day. The big money is made by sitting — by identifying the major swings and riding them. The Market Key is his tool for identifying when those swings begin and end.

Intended Application: The system was designed for actively traded stocks and commodity futures, using daily closing prices. Livermore applied it primarily to railroad stocks and steel stocks in the 1920s-1930s, but presented it as a universal framework adaptable to any liquid market.

2. The Livermore Market Key

2.1 Purpose and Philosophy

The Livermore Market Key is a manual price-tracking system designed to:

• Eliminate emotional bias from trend identification
• Create a mechanical record of trend state for every stock being followed
• Generate clear signals for when a trend has changed direction
• Force the trader to wait for confirmation before acting

Livermore did not use charts. He considered chart reading to be ambiguous and subject to interpretation. The Key, by contrast, produces a definitive classification of the current state of each stock at all times.

2.2 The Six-Column Recording Method

The Key uses a ruled sheet with six columns for each stock being tracked. Every significant price is recorded in exactly one column, based on the current trend state and the rules of the system.

Column	Name	Abbreviation	Ink Color	Meaning
1	Secondary Rally	SR	Black	A rally within a prevailing downward trend
2	Natural Rally	NR	Black	A normal upward correction within a downtrend
3	Upward Trend	UT	Black	The confirmed primary upward trend
4	Downward Trend	DT	Red	The confirmed primary downward trend
5	Natural Reaction	NRe	Red	A normal downward correction within an uptrend
6	Secondary Reaction	SRe	Red	A reaction within a prevailing upward trend

The columns are arranged in this specific order — not as an ascending/descending scale, but as rally columns (1, 2, 3) on the left and reaction columns (4, 5, 6) on the right. Column 3 (Upward Trend) and Column 4 (Downward Trend) are the two primary trend columns in the center.

2.3 Color Coding System

Livermore specified three recording colors to provide instant visual recognition:

• Black Ink: All prices recorded in the three rally/upward columns (Secondary Rally, Natural Rally, Upward Trend). Black signifies upward price movement.
• Red Ink: All prices recorded in the three reaction/downward columns (Downward Trend, Natural Reaction, Secondary Reaction). Red signifies downward price movement.
• Pencil (underline): Key Prices — the last entry in a column before the recording shifts to a different column — are underlined in pencil. These underlined prices become critical reference points for future trend-change signals.

The pencil underlines are the most important visual element. They mark the pivot prices that the system watches for breakouts and breakdowns.

2.4 Price Movement Thresholds

The system requires a minimum price movement before recording shifts from one column to another. Livermore used approximately 6 points as the threshold for railroad stocks (which traded in the $30-$150 range at that time). For other stocks, the threshold was adjusted proportionally.

Threshold Rules:

• A move of approximately 6 points (for rails) from the last recorded price in the current column triggers evaluation of a column change
• Moves smaller than the threshold are ignored — they are noise
• The threshold applies to the closing price, not intraday moves
• For higher-priced stocks, a larger point threshold may be appropriate
• For lower-priced stocks, a smaller threshold applies

Modern Adaptation: Since stock prices and volatility have changed dramatically, a percentage-based threshold (approximately 4-6% for large caps) or an ATR-based threshold is more appropriate than a fixed point value.

2.5 Rules for Recording Prices in Each Column

The rules below govern when and where a price is recorded. These are deterministic — there is no ambiguity once the current state is known.

Rule 1 — Continuation in the Current Column: If today's closing price continues in the direction of the current column (higher for rally columns, lower for reaction columns) by any amount, record it in the current column. The previous entry in that column is not underlined.

Rule 2 — Reversal Exceeding Threshold: If today's closing price reverses from the current column's direction by the threshold amount (approximately 6 points), underline the last entry in the current column (this is now a Key Price), and record today's price in the appropriate reversal column.

Rule 3 — Natural Rally from Downward Trend: When recording in the Downward Trend column (Col 4), if price rallies by the threshold amount, underline the last DT price and record in Natural Rally (Col 2).

Rule 4 — Natural Reaction from Upward Trend: When recording in the Upward Trend column (Col 3), if price reacts by the threshold amount, underline the last UT price and record in Natural Reaction (Col 5).

Rule 5 — Secondary Rally from Natural Reaction: When recording in Natural Reaction (Col 5), if price rallies by the threshold amount but does NOT exceed the last underlined Upward Trend Key Price, record in Secondary Rally (Col 1). This is a rally within a reaction within an uptrend — a minor, unconfirmed move.

Rule 6 — Secondary Reaction from Natural Rally: When recording in Natural Rally (Col 2), if price reacts by the threshold amount but does NOT break below the last underlined Downward Trend Key Price, record in Secondary Reaction (Col 6). This is a reaction within a rally within a downtrend.

Rule 7 — Upward Trend Confirmation: A stock enters the Upward Trend column (Col 3) when the price exceeds the last underlined Key Price in the Upward Trend column, while also being above the last underlined Natural Rally Key Price. This double confirmation is the buy signal.

Rule 8 — Downward Trend Confirmation: A stock enters the Downward Trend column (Col 4) when the price breaks below the last underlined Key Price in the Downward Trend column, while also being below the last underlined Natural Reaction Key Price. This double confirmation is the sell/short signal.

Rule 9 — Combination Rule (Rally Continuation): When recording in Natural Rally (Col 2), if the price rallies above the last underlined Natural Rally Key Price AND the last underlined Upward Trend Key Price, skip Natural Rally and record directly in Upward Trend (Col 3).

Rule 10 — Combination Rule (Reaction Continuation): When recording in Natural Reaction (Col 5), if the price reacts below the last underlined Natural Reaction Key Price AND the last underlined Downward Trend Key Price, skip Natural Reaction and record directly in Downward Trend (Col 4).

2.6 Using the Key to Identify Trend Changes

The Key produces two kinds of actionable signals:

Upward Trend Signal (Buy):

1. Stock has been in Downward Trend or Natural Rally
2. Price rallies above the last underlined Natural Rally Key Price
3. Price also exceeds the last underlined Upward Trend Key Price
4. Record shifts to Upward Trend column (Col 3)
5. This is the signal to begin probing on the long side

Downward Trend Signal (Sell/Short):

1. Stock has been in Upward Trend or Natural Reaction
2. Price reacts below the last underlined Natural Reaction Key Price
3. Price also breaks below the last underlined Downward Trend Key Price
4. Record shifts to Downward Trend column (Col 4)
5. This is the signal to begin probing on the short side

The genius of the system is the double confirmation requirement. A single breakout above a rally high is not enough — the price must also clear the prior upward trend pivot. This filters out many false signals.

3. Pivot Point Theory

3.1 Definition of Pivotal Points

A pivotal point is a price level at which a stock's trend changes character. It is not a mathematical calculation (unlike the modern "pivot point" formula); it is a conceptual framework for identifying moments of maximum opportunity.

Livermore defines pivotal points as prices at which the balance of supply and demand shifts decisively. They are observable in retrospect as the turning points on a price chart, but the Key system is designed to identify them as they form.

3.2 Two Types of Pivotal Points

Continuation Pivotal Points:

• Occur within an established trend
• Represent a pause, consolidation, or minor correction followed by resumption
• The price temporarily reverses, creating a new Key Price (underlined entry)
• When the price then resumes the original trend direction and exceeds the Key Price, the continuation pivotal point is confirmed
• These are opportunities to add to an existing position
• They occur at the Natural Rally / Natural Reaction level — the stock pulls back and then reasserts its primary direction

Reversal Pivotal Points:

• Occur at the end of a major trend
• Represent a genuine change in the primary direction
• The price breaks through Key Prices in the opposite direction from the prior trend
• When the Upward Trend column gives way to Downward Trend (or vice versa) via the double-confirmation rules, a reversal pivotal point is confirmed
• These are opportunities to close existing positions and potentially reverse direction
• They are rarer and more significant than continuation pivotal points

3.3 How to Identify Pivotal Points in Real-Time

Livermore's approach to real-time identification:

1. Watch the Key columns. When a stock shifts from a primary trend column (UT or DT) to a secondary column (NR, NRe, SR, SRe), a potential pivotal point is forming.

2. Monitor the Key Prices. The underlined prices in each column are the pivotal levels. When price approaches one of these levels from the opposite direction, prepare for action.

3. Wait for confirmation. Do not anticipate. The pivotal point is confirmed only when the recording rules shift the stock into the new column. Premature action based on an unconfirmed pivotal point is one of the most common errors.

4. Use volume as secondary confirmation. Livermore noted that genuine pivotal points typically occur on increased volume, though the Key system itself is purely price-based.

3.4 Using Pivotal Points for Entry Timing

• Enter at continuation pivotal points to add to winners
• Enter at reversal pivotal points to initiate new positions in the new direction
• Never enter between pivotal points — this is dead time
• The further a price has moved from the last pivotal point without a new one forming, the higher the risk of entering

---

4. Time Element in Trading

4.1 Why Timing Is Everything

Livermore regarded the time element as equal in importance to price. Being right about direction but wrong about timing produces losses just as surely as being wrong about direction.

The time element manifests in several ways:

• Seasonal patterns in commodity markets
• Accumulation and distribution phases that take weeks or months to complete
• The speed of price movement once a trend is confirmed — fast moves indicate conviction; slow moves indicate uncertainty
• The duration of reactions and rallies — a natural reaction that takes much longer than normal may be transitioning into a trend change

4.2 "The Market Is Never Wrong, Opinions Often Are"

This is Livermore's most fundamental philosophical statement. It means:

• The current price reflects all known information and all participants' actions
• Your opinion about where the price "should" be is irrelevant
• If the market disagrees with your position, the market is right and you are wrong
• The only correct response to a losing position is to exit, not to rationalize

The practical implication: never argue with the tape. If the Key system says the trend is down, it is down, regardless of your opinion about the company's value.

4.3 Waiting for the Right Moment

Livermore was explicit: the trader should do nothing most of the time. The Key system will frequently show stocks in transitional states (Natural Rally, Natural Reaction, Secondary columns) that do not warrant action. Only when the double-confirmation signal fires should the trader act.

Rules for Waiting:

• Do not trade because you are bored
• Do not trade because others are trading
• Do not trade because you feel you "must" do something
• Trade only when the Key gives a confirmed signal at a recognized pivotal point
• Between signals, study the market, update your records, and preserve your capital

4.4 Danger of Premature Action

Livermore lost fortunes by acting too early. His rules against premature action:

• Never buy during a reaction because the stock "looks cheap"
• Never short during a rally because the stock "looks expensive"
• Never commit full capital to a position until the initial probe is confirmed
• Never scale into a losing position — this is averaging down, the cardinal sin

---

5. Entry Rules

5.1 Probing / Testing Positions

Livermore never committed his full intended position at once. He used a staged entry system he called "probing":

Phase 1 — Initial Probe (20% of intended position):

• The Key gives a confirmed trend signal
• Buy (or short) one-fifth of the intended total position
• This is a test — if the market immediately moves against you, the loss is limited
• Set a maximum loss point of 10% from entry on this probe

Phase 2 — Confirmation Probe (20% more):

• If the initial probe shows a profit, buy a second lot at a higher price
• This is counter-intuitive but essential — you are confirming that the trend is real
• The stock must be moving in your direction to justify additional commitment

Phase 3 — Full Commitment (remaining 60%):

• If the second probe also shows a profit, commit the remainder
• At this point you have three confirmations: the Key signal, the first probe's profit, and the second probe's profit
• Your average cost is higher than the initial entry, but your probability of being in a genuine trend is much higher

Abandonment Rule:

• If at any point during probing the position shows a loss exceeding 10% from the average cost, close the entire position immediately
• Do not hope, do not rationalize, do not wait for recovery
• Re-enter only if the Key gives a fresh confirmed signal

5.2 Confirmation Requirements Before Full Commitment

Full commitment requires ALL of the following:

1. The Livermore Market Key has confirmed a trend change (double-confirmation rule)
2. The initial probe is showing a profit
3. The secondary probe at a higher price (for longs) is also profitable
4. The overall market direction (as read from index stocks) is favorable
5. The stock's industry group is moving in the same direction

5.3 The Tandem Trading Concept

Livermore observed that stocks in the same industry tend to move together. He used this observation as a confirmation mechanism:

Tandem Rules:

• Track two leading stocks in the same industry group using the Key
• Both stocks should give confirmed trend signals before trading either
• If Stock A gives a buy signal but Stock B does not confirm, do not trade
• If Stock A gives a buy signal and Stock B shortly follows, this is strong confirmation — trade both
• If one stock in the tandem diverges (reverses while the other continues), this is an early warning sign — tighten stops or reduce position

Example from the book: Livermore tracked US Steel and Bethlehem Steel as a tandem pair. He would not go long on one unless the other confirmed the uptrend. Similarly, he tracked several railroad stocks as a group.

6. Money Management

6.1 Never Lose More Than 10% on a Position

This is Livermore's most rigid rule and the foundation of his capital preservation system.

The 10% Rule:

• From the moment of entry, set a mental (or actual) stop-loss at 10% below the entry price for longs, 10% above for shorts
• If the position moves against you by 10%, close it. No exceptions.
• Do not move the stop further away. Do not average down. Do not hope.
• The 10% figure applies to the average cost of the entire position, including all probes

Rationale: If you are right about the trend, a properly timed entry will not show a 10% loss. A 10% loss means your timing was wrong, and staying in the position is wishful thinking, not trading.

6.2 Capital Preservation Rules

• Never risk your entire capital on one trade. Diversify across several positions in different groups, each managed with the 10% rule.
• After a series of losses, reduce position size. If you lose on three consecutive trades, cut your position size in half. Your judgment may be impaired or the market may be in a trendless phase unsuitable for the system.
• Keep a cash reserve. Never be fully invested. Cash is a position — it preserves optionality for when the next high-confidence signal appears.
• Bank a portion of profits from every successful campaign. Livermore recommended physically removing money from the trading account and placing it in a bank where it could not be accessed for trading. He suggested setting aside 50% of profits from any large winning trade.

6.3 When to Increase Position Size

Position size should increase only when:

• The account has grown through profits (not deposits)
• The current trade is profitable and confirming
• The probing sequence has been fully validated (all three phases profitable)
• The general market is trending strongly in your direction

Position size should decrease when:

• The account has shrunk through losses
• Recent trades have been stopped out
• The market is choppy or trendless
• You feel uncertain or emotionally agitated

6.4 Taking Profits Off the Table After Big Wins

Livermore's profit-taking rules:

1. After a major winning campaign: withdraw 50% of profits from the account. Place this money in a safe, inaccessible savings vehicle.
2. Do not immediately re-invest big profits. Take a break. The euphoria of a big win impairs judgment as surely as the depression of a big loss.
3. If a winning position begins to show signs of trend exhaustion (the Key columns begin oscillating between primary and secondary states rapidly), take partial profits.
4. Never let a large profit turn into a loss. Once a position has moved substantially in your favor, move your mental stop to at least breakeven.

---

7. Emotional Discipline & Psychological Rules

7.1 "Wall Street Never Changes Because Human Nature Never Changes"

Livermore's central psychological insight: the market's patterns repeat not because of any mechanical law, but because human emotions — greed, fear, hope, ignorance — are constant across generations. The trader who masters his own emotions gains an edge over the vast majority who cannot.

7.2 Tips Are Dangerous

Livermore was emphatic: never act on tips. His rules:

• A tip removes the trader's own analysis from the equation
• If the tip is wrong, you have no framework for managing the loss
• If the tip is right, you learn nothing and become dependent on future tips
• Most tips originate from people who want you to buy what they are selling
• The only valid "tip" is what the tape itself tells you through the Key system

7.3 Hope and Fear — The Two Enemies

Livermore identified hope and fear as the twin destroyers of trading accounts, but noted that they operate in precisely the wrong direction:

• When you should feel fear (at a loss), you feel hope. You hope the stock will recover. You hold a losing position far too long.
• When you should feel hope (at a profit), you feel fear. You fear losing the profit. You close a winning position far too soon.

The correct inversion:

• Fear losses. Cut them immediately at the 10% threshold. Never hope they will recover.
• Hope for profits. Let winners run as long as the Key system confirms the trend. Do not fear giving back a portion of open profits.

7.4 The Importance of Independent Thinking

• Do your own analysis using the Key system
• Do not read other people's market opinions
• Do not discuss your positions with others
• Do not seek validation for your trades
• The market will tell you if you are right — through your profit or loss
• Groupthink is the enemy of the speculator; the crowd is almost always wrong at turning points

---

8. Market Timing & General Conditions

8.1 Reading the General Market Direction

Livermore insisted that individual stock selection is secondary to general market direction. His hierarchy:

1. General market direction — determine if the overall market is in an uptrend, downtrend, or trendless phase by applying the Key to market leaders
2. Industry group direction — within a favorable general market, identify the strongest (for longs) or weakest (for shorts) industry groups
3. Individual stock selection — within the strongest group, select the leading individual stocks

Rule: Never fight the general market. Even the best stock in the best group will be dragged down by a bear market. Conversely, many mediocre stocks will rise in a strong bull market.

8.2 Industry Group Analysis

Livermore applied the Key to industry groups, not just individual stocks:

• Track the two or three leading stocks in each major group
• When the leaders in a group all shift to Upward Trend simultaneously, the group is confirming a bull move
• When leaders diverge (some in UT, some in DT), the group is in conflict — avoid it
• The strongest groups in a bull market are the ones to trade; the weakest groups in a bear market are the best shorts

8.3 Leading Stocks as Market Indicators

Livermore used the behavior of market leaders as a proxy for market health:

• If leaders are making new highs and the Key confirms uptrends, the market is healthy
• If leaders begin failing (Key shifts to NR or DT) while secondary stocks are still rising, this is a major warning — the market is distributing
• New market leaders emerge at the beginning of each new bull cycle; the leaders of the previous cycle rarely lead again
• Track a basket of 8-12 leaders across different groups using the Key

---

9. Short Selling Rules

Livermore was equally comfortable on the long and short side. His short-selling rules:

1. The Key must confirm a Downward Trend — the double-confirmation rule applies just as rigorously for shorts as for longs
2. Short into rallies, not into declines — wait for a Natural Rally (Col 2) within a confirmed Downward Trend (Col 4), then short when the rally fails and the Key reverts to DT
3. The best short candidates are former leaders — stocks that led the prior advance and have broken their Upward Trend are the strongest shorts because they have the most holders who will be forced to sell
4. Short selling is more difficult because declines are typically faster and sharper than advances, rallies in bear markets are violent, and psychological pressure is greater (the crowd hates short sellers)
5. Use the same probing method — initial probe at 20%, confirm, then commit
6. The same 10% stop-loss applies on the upside for short positions
7. Cover shorts when the Key shifts from DT to NR for the first time after a long decline — this is the first sign that selling pressure is exhausting
8. Never short a dull, quiet market — short only when the Key is actively confirming the downtrend with declining prices

---

10. Common Mistakes

Livermore catalogued the errors he observed (and committed) over four decades:

1. Averaging down. Adding to a losing position. This is the single most destructive practice. The 10% rule exists to prevent it.

2. Overtrading. Trading too frequently, in too many stocks, with too much capital. Quality of trades matters far more than quantity.

3. Acting on tips. Surrendering your own judgment to someone else's opinion.

4. Fighting the trend. Buying in a confirmed downtrend because a stock "looks cheap." Shorting in a confirmed uptrend because a stock "looks expensive."

5. Impatience. Entering before the Key confirms. Livermore calls this "jumping the gun" and identifies it as the product of boredom and ego.

6. Failing to cut losses. Holding a losing position because of hope. This single mistake has ruined more speculators than all others combined.

7. Taking profits too soon. Closing a winning position at the first sign of a reaction, rather than waiting for the Key to shift columns.

8. Changing your method mid-trade. Entering based on the Key system, then abandoning the system when the position is under stress. The method must be followed mechanically.

9. Trading for excitement. The market is not entertainment. When you feel excited, you are vulnerable.

10. Neglecting the time element. Forcing trades when the market is in a trendless, choppy phase. The correct action is to do nothing and wait.

11. Ignoring general market conditions. Trading individual stocks without reference to the overall market direction.

12. Over-leveraging. Using excessive margin. Leverage amplifies both gains and losses. Livermore was destroyed several times by excessive leverage.

11. Complete Trade Lifecycle Example

The following example is modeled on Livermore's own presentations in the book, using his method applied to a hypothetical stock. Livermore used US Steel and railroad stocks in his examples.

Setup — Tracking US Steel with the Key

Background: US Steel has been in a Downward Trend. The last several entries have been in Column 4 (DT, red ink). The underlined Key Prices are:

Column	Last Key Price (underlined)
Upward Trend (Col 3)	88
Natural Rally (Col 2)	82
Downward Trend (Col 4)	70 (current column, latest: 68)
Natural Reaction (Col 5)	75

Phase 1 — Natural Rally Develops

US Steel closes at 74 (up 6 from 68). The threshold is met. Underline 68 in the DT column. Record 74 in the Natural Rally column (Col 2, black ink).

Over the next several days, US Steel continues to rally: 75, 77, 79, 80. Each price is recorded in the NR column.

Phase 2 — Key Question: Continuation or Reversal?

US Steel closes at 83. This exceeds 82 (the last underlined NR Key Price). We now check: does it also exceed 88 (the last underlined UT Key Price)?

83 does NOT exceed 88. Therefore, record 83 in the Natural Rally column. This is a strong rally but not yet a confirmed Upward Trend.

Phase 3 — Continued Rally to Pivotal Point

US Steel closes at 89. This exceeds BOTH 82 (last NR Key Price) AND 88 (last UT Key Price). Under Rule 7/Rule 9, this is a double-confirmed Upward Trend signal. Underline the last NR entry (83). Record 89 in the Upward Trend column (Col 3, black ink).

Action: This is the first buy signal. Initiate the probing sequence.

Phase 4 — Initial Probe

Buy 200 shares of US Steel at 89 (20% of intended 1,000-share position). Set mental stop at 80.10 (approximately 10% below entry).

Phase 5 — Tandem Confirmation

Check Bethlehem Steel (tandem stock). Its Key has also recently shifted to Upward Trend. Confirmed. The signal is valid.

Phase 6 — Second Probe

US Steel closes at 92, then 94. The initial probe is profitable by 5 points. Buy 200 more shares at 94. New average cost: 91.50 for 400 shares.

Phase 7 — Full Commitment

US Steel closes at 97, then 99. Both probes are profitable. Buy remaining 600 shares at 99. Total position: 1,000 shares, average cost approximately 96.

Phase 8 — Riding the Trend

US Steel continues: 101, 104, 108, 112. All entries go into the Upward Trend column (Col 3). The trader does nothing except record prices and enjoy the profit.

Phase 9 — Natural Reaction Develops

US Steel drops from 112 to 106 (a 6-point reaction). Underline 112 in the UT column. Record 106 in Natural Reaction (Col 5, red ink).

Action: Do nothing. A Natural Reaction within an Upward Trend is normal. The trend is still intact. Continue to hold.

Phase 10 — Continuation Pivotal Point

US Steel rallies from 106 back to 113, then 118. The reaction from 112 to 106 and resumption to 118 creates a continuation pivotal point. Record prices back in the UT column. This confirms the uptrend is still alive.

Action: Could add to position here (Livermore sometimes did at continuation pivotal points), but the probing sequence has already been completed.

Phase 11 — Warning Signs

US Steel reaches 125, then reacts: 119, 117, 115. Underline 125 in UT column. Record 119, 117, 115 in Natural Reaction (Col 5). Then a rally: 118, 120. But 120 does NOT exceed the last underlined UT Key Price (125). Record in Secondary Rally (Col 1).

Then another decline: 114, 111. This goes into Natural Reaction again. Then another weak rally to 116 — still below the Key Prices. The stock is oscillating in secondary columns, failing to confirm a continuation.

Action: The oscillation between secondary columns is a warning. Tighten the mental stop. Livermore would move the stop to at least breakeven (96) or higher.

Phase 12 — Exit Signal

US Steel drops to 108. This breaks below the last underlined Natural Reaction Key Price (106). Check: does it also break below the last underlined Downward Trend Key Price (70)? No — that is far away. So this is a Natural Reaction, not yet a Downward Trend.

But Livermore also watches the tandem. Bethlehem Steel has already shifted to Downward Trend on its Key. The tandem is diverging.

Action: Close the position at 108. Profit: approximately 12 points per share on 1,000 shares, or $12,000. Withdraw $6,000 (50% of profit) to the bank.

Summary of Lifecycle

Phase	Action	Price	Rationale
Signal	Key confirms UT	89	Double-confirmation rule
Probe 1	Buy 200	89	Test the signal
Probe 2	Buy 200	94	Probe 1 profitable
Full commit	Buy 600	99	Both probes profitable
Hold	—	99-125	Key in UT column, trend intact
Warning	Tighten stop	120	Secondary oscillation, tandem divergence
Exit	Sell 1,000	108	Key deterioration, tandem failure
Protect	Bank $6,000	—	50% of profits banked

13. Key Quotes

"There is nothing new in Wall Street. There can't be because speculation is as old as the hills. Whatever happens in the stock market today has happened before and will happen again."

"The market is never wrong — opinions often are."

"It was never my thinking that made the big money for me. It always was my sitting. Got that? My sitting tight!"

"Profits always take care of themselves, but losses never do. The speculator has to insure himself against considerable losses by taking the first small loss."

"Do not use the word 'cheap' or 'dear' in the stock market. A stock is never too high to buy and never too low to sell short."

"The speculator's chief enemies are always boring from within. It is inseparable from human nature to hope and to fear."

"When you have made money in the market and you feel like splurging — take some of that profit and put it in the bank. Put it in a safe deposit box. Let it accumulate there. The one sure thing about the stock market game is that the money you have taken out and put away, you will always have."

"Tips! How people want tips! They crave not just tips, but inside tips. There is something about a tip that is like a drug to these people."

"In a bull market your game is to buy and hold until you believe that the bull market is near its end. To do this you must study general conditions and not tips or special factors affecting individual stocks."

"The human side of every person is the greatest enemy of the average investor or speculator."

"A prudent speculator never argues with the tape. Markets are never wrong, but opinions often are."

"Remember, it is dangerous to start spreading out all over the market. Do not have an interest in too many stocks at one time. It is much easier to watch a few than many."

Implementation compiled from Jesse Livermore, How to Trade in Stocks (1940). The Livermore Market Key pseudocode is a systematic reconstruction of the recording method described in Chapters 2-5 of the original text.
