Based on Alexander Elder, Come Into My Trading Room: A Complete Guide to Trading (2002) and subsequent updates
Alexander Elder, M.D. (born 1950 in Leningrad, emigrated from the Soviet Union in 1974), is a professional trader, psychiatrist, and author whose works on trading psychology and methodology have become foundational texts in trading education. His first book, Trading for a Living (1993), introduced the Triple Screen trading system and the psychological framework for understanding why traders fail. Come Into My Trading Room (2002) — effectively "Trading for a Living II" — extends and refines every aspect of that earlier work.
The sequel reflects nearly a decade of additional market experience and the evolution of Elder's thinking. The Triple Screen system is updated with more sophisticated indicator choices. The Impulse System is introduced as a new tool for trend-momentum alignment. The 2% and 6% money management rules are articulated with greater precision. And the trader's diary methodology is presented as the essential tool for self-improvement.
Elder approaches trading as a profession that requires three foundational pillars, each equally important:
| Pillar | Focus | Key Concept |
|---|---|---|
| Mind | Trading psychology | Self-discipline, emotional control, self-awareness |
| Method | Market analysis and trading systems | Triple Screen, Impulse System, indicator mastery |
| Money | Risk management and capital preservation | 2% Rule, 6% Rule, position sizing |
Failure in any one pillar leads to failure overall, regardless of strength in the other two. A brilliant analyst with poor discipline will overtrade. A disciplined trader with poor risk management will be destroyed by a single catastrophic loss. A risk-conscious trader with no analytical method will slowly bleed capital through random entries.
Key changes from Trading for a Living to Come Into My Trading Room:
Triple Screen is Elder's signature methodology. It addresses the fundamental problem that indicators designed to capture trends and indicators designed to identify reversals give conflicting signals when applied to the same timeframe. The solution: use different indicators on different timeframes.
The three screens:
First screen (strategic) — The tide. Uses a trend-following indicator on a higher timeframe to determine the strategic direction. This is the filter. You only take trades in the direction of this screen.
Second screen (tactical) — The wave. Uses an oscillator on the intermediate timeframe to identify entry points against the short-term direction but with the strategic direction. Pullbacks within the trend.
Third screen (precision) — The ripple. Uses the lowest timeframe for precise entry timing — a trailing buy stop (for longs) or trailing sell stop (for shorts).
Elder recommends choosing timeframes that are approximately a factor of five apart:
| Strategic (1st Screen) | Tactical (2nd Screen) | Precision (3rd Screen) |
|---|---|---|
| Weekly | Daily | Intraday (hourly) |
| Daily | Hourly | 15-minute |
| Monthly | Weekly | Daily |
The most common combination for swing traders: weekly-daily-intraday.
In the original Triple Screen, the first screen used the slope of the weekly MACD histogram. In the updated version, Elder refines this:
Primary indicator: Weekly EMA (13-week EMA).
Secondary confirmation: Weekly MACD histogram.
The second screen uses an oscillator on the daily chart to identify pullback entries in the direction of the weekly trend:
Primary indicator: Force Index (2-day EMA).
Alternative indicators:
The third screen uses an intraday trailing stop for entry:
For longs (weekly trend up, daily oscillator gives buy signal): Place a buy stop one tick above the high of the previous day. If triggered, you are entered on strength. If not triggered, lower the buy stop to one tick above the high of the current day. Continue for up to three days. If not triggered in three days, cancel — the signal has expired.
For shorts (weekly trend down, daily oscillator gives sell signal): Place a sell stop one tick below the low of the previous day. Same trailing logic.
The Impulse System is Elder's most significant new contribution. It is a color-coded system that identifies when a trend and its momentum are aligned (safe to trade) and when they are diverging (stand aside or expect a reversal).
The system uses two indicators:
Color coding:
| EMA Direction | MACD-H Direction | Color | Meaning |
|---|---|---|---|
| Rising | Rising | Green | Trend and momentum aligned bullish — OK to buy, do NOT short |
| Falling | Falling | Red | Trend and momentum aligned bearish — OK to short, do NOT buy |
| Rising | Falling | Blue (neutral) | Trend up but momentum waning — caution, may be topping |
| Falling | Rising | Blue (neutral) | Trend down but momentum improving — caution, may be bottoming |
The Impulse System gains power when applied across multiple timeframes:
Elder Ray measures the power of bulls and bears separately:
Bull Power = High - EMA(13). Measures how far buyers can push price above the consensus value (EMA). Positive bull power in an uptrend confirms strength. Declining bull power warns of weakening demand.
Bear Power = Low - EMA(13). Measures how far sellers can push price below consensus. Negative bear power in a downtrend confirms weakness. Rising bear power (becoming less negative) warns of weakening supply.
Buy signal: EMA rising, Bear Power negative but rising (sellers losing power within an uptrend).
Sell signal: EMA falling, Bull Power positive but falling (buyers losing power within a downtrend).
The Force Index combines price change, volume, and direction into a single number:
Force Index = Volume x (Close - Previous Close)
Elder smooths the Force Index with a 2-day EMA for short-term trading signals and a 13-day EMA for intermediate signals:
Elder refines the classic MACD with emphasis on the histogram rather than the signal line:
Bullish divergence: Price makes a lower low but the MACD histogram makes a higher low. This indicates that selling momentum is weakening even as price declines — one of the strongest buy signals in technical analysis.
Bearish divergence: Price makes a higher high but the MACD histogram makes a lower high. Buying momentum is weakening even as price advances — a strong sell signal.
Elder's rule: Divergences that occur between two bottoms (or peaks) of the MACD histogram separated by a crossing of the zero line are more significant than those within a single trend leg.
For market analysis (not individual stocks), Elder uses the New High-New Low (NH-NL) Index:
Never risk more than 2% of your trading account equity on any single trade.
This is Elder's most famous risk management principle. The 2% limit refers not to the position size but to the maximum loss — the distance between entry and stop loss, multiplied by the number of shares or contracts.
The 2% rule exists for mathematical survival:
If you risk 2% per trade and have a catastrophic losing streak of 10 consecutive losses (which is statistically improbable with any reasonable system), you lose approximately 18% of your capital. This is painful but recoverable.
If you risk 10% per trade and have the same losing streak, you lose approximately 65% of your capital. This is essentially a death sentence for the account.
Account equity: $100,000
Maximum risk per trade: $100,000 x 0.02 = $2,000
Stock price: $50.00
Stop loss: $47.00
Risk per share: $3.00
Maximum shares: $2,000 / $3.00 = 666 shares
Position value: 666 x $50.00 = $33,300 (33.3% of equity)
Note that the 2% rule may result in large position sizes (as a percentage of equity) when the stop is tight, or small position sizes when the stop is wide. This is correct and intentional — it ties position size to the actual risk of the trade, not to an arbitrary percentage of capital.
Elder notes that 2% is the maximum, not the target:
If your total open risk across all positions plus closed losses for the current month reach 6% of your account equity at the start of the month, stop trading for the remainder of the month.
The 6% rule is the portfolio-level equivalent of the 2% rule. While the 2% rule limits the damage from any single trade, the 6% rule limits the damage from a series of bad trades or from an adverse market environment.
The logic: if you have lost 6% of your equity in a month, something is wrong — either your analysis is off, the market environment has changed, or your psychology is impaired. In any of these cases, the correct response is to stop trading and reassess, not to trade harder to recover.
The 6% calculation includes both realized losses and unrealized (open) risk:
Account equity at start of month: $100,000
6% limit: $6,000
Open positions:
Position A: Risking $1,200 (entry $50, stop $48, 600 shares)
Position B: Risking $1,500 (entry $30, stop $27, 500 shares)
Position C: Risking $800 (entry $80, stop $78, 400 shares)
Total open risk: $3,500
Closed losses this month: $1,800
Total exposure: $3,500 + $1,800 = $5,300
Remaining before 6% trigger: $6,000 - $5,300 = $700
In this example, the trader can only risk $700 more this month. If another position is stopped out or if the trader wants to open a new position, they must stay within this remaining budget. If the total reaches $6,000, trading stops for the month.
When the 6% limit is hit:
| Account Size | 2% Risk Per Trade | 6% Monthly Limit | Notes |
|---|---|---|---|
| $10,000 | $200 | $600 | Very constrained; few positions possible |
| $25,000 | $500 | $1,500 | Minimum practical size for swing trading |
| $50,000 | $1,000 | $3,000 | Comfortable for 3-5 positions |
| $100,000 | $2,000 | $6,000 | Standard; 4-6 positions typical |
| $500,000 | $10,000 | $30,000 | Consider reducing to 1% / 4% |
Elder recommends tightening the rules during drawdowns:
The tightening is automatic and removes emotion from the decision. It functions as a circuit breaker, preventing a losing streak from cascading into catastrophe.
The 2% rule determines the maximum number of shares per trade. The 6% rule determines the maximum number of open trades. Together, they create a complete risk management framework:
This creates a natural relationship between conviction (higher risk per trade, fewer positions) and diversification (lower risk per trade, more positions).
Elder argues that the trading diary is the single most powerful tool for self- improvement available to traders. Yet fewer than 5% of traders maintain one. This is because the diary forces honesty — it creates an irrefutable record of what you did, why you did it, and what happened.
For every trade, Elder recommends recording:
Before entry:
At entry:
During the trade:
At exit:
Every weekend, Elder recommends reviewing the week's trades:
At the end of each month:
Elder, drawing on his psychiatric training, identifies three stages that most traders progress through:
Stage 1: The Unconscious Incompetent. The beginner who does not know what they do not know. Characteristic behaviors: overtrading, no risk management, chasing tips, emotional decision-making, belief that a "magic indicator" exists.
Stage 2: The Conscious Incompetent. The trader who has experienced losses and now understands the difficulty of trading but has not yet developed the skills to succeed. This is the most dangerous stage because the trader understands enough to be tempted by sophisticated-seeming approaches but lacks the discipline to execute consistently.
Stage 3: The Conscious Competent. The trader who has developed a tested methodology, applies disciplined risk management, and maintains emotional equilibrium. This trader wins not through brilliance but through consistency. They follow the plan, manage risk, and let the edge play out over many trades.
The rare Stage 4: The Unconscious Competent — the master who trades intuitively because the discipline has become automatic. Very few reach this level, and those who do typically have decades of experience.
Elder identifies the key psychological traps around losing:
Elder prescribes specific practices:
Elder recommends a top-down approach:
Elder places special emphasis on divergences as the most powerful signals in technical analysis:
Divergences do not provide timing (the market can remain divergent for extended periods) but they provide direction with high reliability. They are most powerful when they occur on the weekly chart and are confirmed by daily signals.
Elder's approach to support and resistance emphasizes:
Elder insists that every trade must have a written plan before entry:

Elder introduces a systematic grading system:
Entry grade:
Management grade:
Exit grade:
Elder recommends tracking these metrics monthly:
| Metric | Formula | Target |
|---|---|---|
| Win rate | Winning trades / Total trades | 50-60% |
| Average win | Sum of gains / Number of winners | > 2x average loss |
| Average loss | Sum of losses / Number of losers | < 0.5x average win |
| Profit factor | Gross gains / Gross losses | > 2.0 |
| Maximum drawdown | Peak-to-trough decline | < 15% |
| Expectancy | (Win% x Avg Win) - (Loss% x Avg Loss) | Positive |
| Sharpe ratio | (Avg return - Risk free) / Std dev | > 1.0 |
At the end of each month, compile:
"The goal of a successful trader is to make the best trades. Money is secondary."
"The 2% Rule will keep you in the game long enough for your edge to work. Without it, you are one bad streak away from ruin."
"The markets are a court of law, but there is no jury of your peers. The market is the judge, and its verdict is final."
"A losing trade is not a mistake if you followed your plan. A winning trade is a mistake if you didn't follow your plan. Process, not outcome, defines quality."
"The Impulse System is a traffic light for traders. Green means go. Red means stop. Blue means proceed with caution. Most traders run every red light and wonder why they crash."
"The trading diary is not a punishment. It is the fastest path to improvement available to any trader. The traders who keep diaries improve. The traders who don't repeat their mistakes indefinitely."
"If you are losing more than 6% of your account in a month, something is wrong — with your analysis, with your discipline, or with the market environment. In all three cases, the correct response is to stop and reassess, not to trade harder."
"Triple Screen works because it resolves the fundamental conflict in technical analysis: trend-following indicators and oscillators give opposite signals on the same timeframe. By separating them across timeframes, the conflict disappears."
"The amateurs look for challenges; the professionals look for easy trades. The professionals patiently wait for the easy ones and avoid the rest."
"Risk management is not a part of trading. It IS trading. Everything else is just opinion."
"Most traders fail not because they lack knowledge, but because they lack the discipline to apply the knowledge they already have."
This specification synthesizes Alexander Elder's extended trading education framework. The three pillars — Mind, Method, and Money — must all be strong for trading success. The Triple Screen system provides a structured approach to multi-timeframe analysis, the Impulse System adds a momentum-trend alignment filter, and the 2%/6% money management rules provide mathematical protection against ruin. The trading diary transforms subjective experience into objective data that enables continuous improvement. Elder's psychiatric background gives his psychological insights particular depth — he understands not just what traders do wrong, but why they do it and how to build the self-awareness that prevents repetition.
