Come Into My Trading Room

Dr. Alexander Elder · 2002 · 322 pages

Elder's real contribution is not a trading system, it is a risk cage: the 2% and 6% Rules that stop one bad trade or one bad month from ending your account. The Triple Screen entry method wrapped around them is serviceable but shows its age.

The one idea

The book organizes trading around three M's: Mind, Method, and Money. Mind is discipline, Method is Triple Screen (a multi-timeframe way of finding entries), and Money is a pair of hard percentage caps that limit how much of your account any single trade or losing streak can take. Elder's argument is that most losing traders fail on Mind and Money, not Method, so a mediocre system with strict risk rules beats a brilliant system without them.

Triple Screen works by picking a favorite chart timeframe (called intermediate), multiplying it by five to get a long-term timeframe, and letting the long-term chart decide direction only. You go long, short, or stand aside based on the slope of a moving average one level up, then drop back down to the intermediate chart to time entries with an oscillator, and optionally to a short-term chart to fine-tune the actual order. The Impulse System is a faster companion tool: when a 13-day EMA and MACD-Histogram both point the same way, that bar gets flagged green or red, and you are told never to trade against it even if a pattern looks tempting.

The money management layer is where the book earns its keep. The 2% Rule limits any single trade's risk to 2% of trading equity. The 6% Rule stops all trading for the rest of the month once open losses hit 6% of equity measured from the start of that month. Together they force position size down after losses and let it grow after wins, which is a mechanical way of doing what discretionary traders claim to do but rarely manage under pressure.

What it actually teaches

Elder's process runs from strategic direction down to position size, in this order:

  1. SET THE LONG-TERM TREND (SCREEN ONE)

    Pick your favorite chart timeframe and call it intermediate (Elder uses daily). Multiply it by five to get the long-term timeframe (weekly). Apply a trend-following indicator there, in this edition Elder says he now prefers the slope of a 26-week EMA over the original weekly MACD-Histogram slope he used in Trading for a Living. A rising weekly EMA means trade long or stand aside; a falling one means short or stand aside. You never trade against this.

  2. TIME THE ENTRY (SCREEN TWO)

    Drop back to the intermediate (daily) chart and use an oscillator to find entries in the direction the weekly chart already set. In an uptrend, wait for a daily oscillator, MACD-Histogram, Stochastic, or a two-day EMA of Force Index, to dip, giving a buy signal on a pullback rather than a breakout high. Reverse for downtrends: wait for the oscillator to rally before shorting.

  3. TRIGGER THE ORDER (SCREEN THREE)

    Without real-time data, place a buy order at the prior day's high (or a tick above) when the first two screens agree bullish, or a sell order at the prior day's low when they agree bearish, good for one day only. This catches a breakout in the direction the weekly trend already confirmed.

  4. CHECK IT AGAINST THE IMPULSE SYSTEM

    Before taking the Triple Screen signal, check whether the 13-day EMA and MACD-Histogram are both pointing the same direction on the entry timeframe. If the Impulse System is flashing a sell signal, do not buy no matter how good the setup looks; wait for the sell signal to disappear first.

  5. SIZE THE TRADE WITH THE 2% RULE

    Never risk more than 2% of trading equity on one trade. On a $50,000 account that is $1,000. If you buy at $20 with a stop at $18 (a $2 per share risk), divide $1,000 by $2 for a theoretical maximum of 500 shares, then round down further for commissions and slippage, Elder's own worked example lands on 400.

  6. CAP THE MONTH WITH THE 6% RULE

    Track total open risk across all positions. Once combined risk from the start of the month reaches 6% of equity, close everything and stop trading for the rest of that month. A stop moved to breakeven removes that position from the 6% count, freeing room for new trades even while others stay open.

  7. EXIT ON SAFEZONE OR THE CHANNEL LINE

    Place stops with the SafeZone indicator, which trails price by a multiple of the average penetration below the prior day's low (in uptrends) built from a lookback EMA, rather than the obvious swing-low level everyone else uses. Take profits near the upper or lower channel line drawn around a moving average that contains roughly 95% of recent prices, or exit a momentum trade the moment the Impulse System's two indicators stop agreeing.

What it looks like Monday morning

A reader who takes this book seriously stops sizing trades by feel and starts every week the same way: mark the equity balance, calculate 2% and 6% of it in dollars, and write those two numbers down before looking at a single chart. That alone changes behavior more than any indicator in the book, because it forces a stop-loss distance to translate into a share count instead of the other way around.

The second change is timeframe discipline: pick one chart to trade off of, multiply it by five, and only take signals that agree in that direction. It will not by itself make trades profitable, since Elder never claims the Triple Screen entries carry a proven statistical edge, but it removes the specific failure mode of buying a daily dip inside a weekly downtrend, which is where a lot of undisciplined losses come from.

Elder's 'OK to Trade' futures spreadsheet: a $30,000 account, 2% risk cap ($600), checked against each market's noise level (SafeZone x 2)
FutureUnit valueSafeZoneSafeZone x22% of $30,000OK to trade?
S&P$25010.00$5,000$600No

Gold$1001.80$360$600Yes
Crude Oil$4200.76$638$600No
Euro$$2,5000.09$450$600Yes

If SafeZone x2 exceeds 2% of equity, the market's normal noise alone can blow through a compliant stop, so Elder rules it out at that account size.

Where it fails

  • No backtest, anywhere, for any method in the book. Every technique, Triple Screen, the Impulse System, Market Thermometer, SafeZone, is illustrated with a single annotated chart of a trade that worked. There is no win-rate table, no drawdown curve, no out-of-sample test. The 25% annual return with under 10% drawdown Elder cites as 'the performance standard for professional money managers' in Chapter 9 is asserted, not sourced or demonstrated with his own systems.
  • The original Triple Screen rule was already revised once, inside this same book. Elder states plainly that the original version used the slope of weekly MACD-Histogram as the trend filter, and that he now prefers the slope of a 26-week EMA instead. A reader relying on either the MACD-Histogram version from Trading for a Living (1993) or citing '26-week EMA' as a fixed rule from this 2002 edition is quoting a moving target; there is no reason to think the preference stopped evolving after 2002.
  • Chapter 9 is a condensed rerun of Trading for a Living (1993). The book is explicitly built from three sources: new material, the earlier Trading for a Living, and Come Into My Trading Room diary excerpts. A reader who already owns Trading for a Living is paying for a second copy of a large chunk of it repackaged under a new title, which is padding dressed as a 'complete guide.'
  • Market structure it assumes is gone. The day-trading chapter leans on floor traders, pit scalping, and bid/ask spread mechanics ('a tick below the market... a tick above') from an open-outcry era. US equities moved to full electronic trading and decimalized pricing years after this was written, and the specific spread and slippage dynamics described no longer match how most retail order flow is executed.
  • The money management math assumes an account size the reader may not have. The 'OK to Trade' futures spreadsheet (Table 7.1) is built around a $30,000 account and rules out most futures markets outright at that size because their SafeZone noise exceeds 1% of equity. Elder's own worked 2% example uses $50,000 and $100,000 accounts. A trader with $5,000 to $10,000, a realistic starting point for many beginners, cannot apply several of the book's own worked examples without first saving several times that amount.
  • Every chart example shows a trade that worked. The book has no chapter of losing trades walked through step by step, only wins annotated after the fact. Even the diary excerpts in Part Three read as a highlight reel. A reader never sees what a Triple Screen or Impulse System false signal looks like in real time, only in hindsight where the eventual outcome is already known.

Who it is for

Buy it if

You already have a technical entry method you trust and want a rigorous, mechanical position-sizing and drawdown-control layer to bolt onto it. The 2% and 6% Rules and the record-keeping chapter are worth the price on their own.

Skip it if

You are looking for a single system with a tested edge, or you already own Trading for a Living and don't want to pay again for a large overlapping chunk of it. Day-traders relying on the floor-trading and bid/ask mechanics in Chapter 6 should treat that section as historical background, not current market structure.
