The Complete Guide to Day Trading

Markus Heitkoetter · 2008 · 296 pages

A coach's checklist for building any day trading strategy: pick a market, pick an approach, then obsess over exits and testing before you risk money. The indicators are textbook definitions, not a system, so you still have to build the edge yourself.

The one idea

Heitkoetter frames day trading as a seven-step manufacturing process rather than a single method: select a market, select a timeframe, select a trading approach, define entries, define exits, evaluate the strategy, then improve it. The book's real argument is that most traders get this order backwards. They chase entry signals first and treat exits as an afterthought, when the exit rules (stop loss, profit target, trailing stop, time-stop) are what actually decide whether a strategy makes money.

The second half of the book is a checklist for judging whether a strategy is real or curve-fitted: the 10 Power Principles. Use fewer than ten rules, trade electronic and liquid markets, keep a 1:1.5 risk-to-reward ratio at minimum, generate at least five trades a week, test on at least 200 trades, and expect a 60-80% win rate with a 1.3-2.5 profit factor from anything legitimate. Numbers far outside that range, in either direction, are the tell of an over-optimized system that will die on contact with live markets.

The last third pivots from mechanics to psychology: the seven mistakes traders repeat (not taking profits, not limiting losses, overtrading out of greed, revenge, or boredom), and a list of the habits of traders who actually survive. None of it is proprietary. It is a coach's field notes on why traders with a workable plan still blow up, because they cannot follow it.

What it actually teaches

The book walks through building a strategy in the same order it should be built, from choosing what to trade down to proving the strategy actually works.

  1. SELECT A MARKET

    Match the market to your account size before anything else. The book's own numbers: at least $25,000 to day trade stocks (the Pattern Day Trading Rule), $5,000 to $10,000 for futures, $1,000 to $5,000 for options, and as little as $500 to start in forex. Picking a market you can't actually fund with proper position sizing is the first mistake.

  2. SELECT A TIMEFRAME

    Pick one timeframe and build the rest of the strategy around it. The book doesn't hand you a specific timeframe, but everything downstream (entry rules, exit rules, time-stops) is defined relative to whatever bar interval you choose.

  3. SELECT A TRADING APPROACH

    Classify the market as trending or sideways, then pick a matching indicator. Trend-following tools: a 5-10 day moving average crossover (buy above, sell below), a fast/slow moving average cross (e.g. 14-bar over 20-bar), Turtle-style breakouts (buy above the prior 20-bar high, sell below the prior 20-bar low), and MACD (12-bar EMA minus 26-bar EMA, with a 9-bar signal line). Trend-fading tools for sideways markets: Williams %R (sell above 80, buy below 20), RSI (sell crossing down through 70, buy crossing up through 30, 14-period), and Bollinger Bands (21-bar moving average, 2 standard deviations, buy below the lower band, sell above the upper band). You need one approach for each market condition, not one approach used everywhere.

  4. DEFINE ENTRY POINTS

    State the entry rule in two lines or less. If you can't write it that short, it's too complicated to execute when the market is actually moving.

  5. DEFINE EXIT POINTS

    Apply three exit rules on every trade: a stop loss, a profit target, and a time-stop. Each can be set as a fixed dollar amount, a percentage of price, a percentage of volatility (using Average True Range), or a technical level like support/resistance. Keep the reward-to-risk ratio at 1:1.5 or better (a $100 stop needs at least a $150 target). A time-stop should run about three times your bar length; on 15-minute bars, exit after 45 minutes if nothing has happened.

  6. EVALUATE THE STRATEGY

    Back-test, paper trade, or run a Monte Carlo simulation before committing real money, and use at least 40 trades for a minimally valid read (200 trades is the point where the margin of error drops from a shaky 14% at 50 trades to a much tighter 7%; every trade past 200 buys you less). Check net profit, average profit per trade, win rate, and profit factor (gross profit divided by gross loss; look for 1.5 or higher, and get suspicious above 3.0). Take your worst drawdown so far and double it: that's what you should be prepared to sit through.

  7. IMPROVE THE STRATEGY

    Adjust exits, not entries, and watch the whole performance report, not just net profit, when you do. The book's warning example is a real system it found with an entry rule stacking six-plus indicator filters (regression slopes, MACD difference, day-of-week exclusions) that had been tuned until it stopped losing in the test window; it calls this curve-fitting and says it will fail live. Its own worked example instead tests one parameter (a breakout threshold called TF_Param) across a range, looks for where profit, drawdown, average trade, and win rate all stay solid together (0.25 to 0.5), and picks a value from the middle of that stable range (0.3), not the single best-performing value.

What it looks like Monday morning

Before touching a chart, size the account to the market: forex if you have a few hundred dollars, futures at $5,000-plus, options with $1,000-5,000, stocks only past $25,000. Then pick exactly two trading approaches from the book's list, one for trending conditions (moving average cross, MACD, or a 20-bar breakout) and one for sideways conditions (RSI, Williams %R, or Bollinger Bands), and write both entry rules down in two lines each.

Before any of that goes live, run it on a paper account for at least 40 trades with a hard stop loss and profit target on every single trade at a 1:1.5 ratio or better, then pull a performance report and check the win rate and profit factor against the book's ranges (60-80% wins, 1.3-2.5 profit factor) before deciding the strategy is worth funding for real.

Number of tradesMargin of error
5014%
10010%
2007%

The book sets 40 trades as the bare minimum for a valid read and 200 as the point of diminishing returns; each additional 100 trades past 200 only tightens the margin by about 2%.

Where it fails

  • The market-structure case study is a relic of this edition's era. The book's central back-testing lesson uses the E-mini S&P's daily range collapsing from 100-150 ticks in 2000 to 40-60 ticks in 2004, and credits the 2001 Pattern Day Trading Rule and the shift from pit to electronic trading for killing trend-following systems of that period. It's a good lesson in regime change, but the specific data, the pit-versus-electronic contrast, and the 'trade electronic markets for lower commissions' advice (Power Principle #2) are all from a market structure that no longer exists; nearly everything is electronic now and the comparison reads as history, not guidance.
  • No indicator in the book is shown with actual back-tested performance. RSI, MACD, Williams %R, Bollinger Bands, and moving average crossovers are each explained with textbook definitions and thresholds (RSI 30/70, %R 20/80, 21-bar Bollinger) and a single illustrative chart, but none is shown with a win rate, profit factor, or drawdown. The only strategy the book actually walks through optimizing (the anonymized 'TF_Param' breakout system) never discloses its full rule set or its resulting numbers, so the reader has a framework for testing a strategy but no tested strategy to test.
  • The book steers repeatedly toward the author's own company. Paper trading accounts, the performance-tracking spreadsheet, the trading plan template, and a 'fully disclosed trading strategy' are all offered as free downloads from Rockwell Trading, the author's coaching business, rather than built into the book itself. Appendices C, D, F, and G (Additional Resources, Reading Resources, About the Author, Coaching Programs) function as a funnel into paid coaching, not additional instruction.
  • The dollar examples assume a cost structure that's gone. The $2,000-per-futures-contract and $25,000-for-stocks minimums, along with a casual '$10 or less per trade' commission assumption used throughout the worked examples, predate zero-commission stock and options brokers. The math itself (position sizing, weekly profit targets, the $300-win/$200-loss scenario) still works as a template, but the numbers plugged into it need to be rebuilt for current commission and margin structures before they mean anything.
  • It quietly assumes you already have a live data and testing setup. Back-testing, Monte Carlo simulation, and the TF_Param optimization walkthrough all lean on Genesis Financial Trade Navigator, a paid third-party platform named directly in the text, and the book never explains what to do if you're testing in something else. A reader with only a broker's basic charting package will hit a wall trying to reproduce the optimization curves shown as static images.

Who it is for

Buy it if

You're building your first strategy from zero and want a structured checklist for the order of operations (market, timeframe, approach, entry, exit, testing) plus a sanity-check list (the 10 Power Principles) for judging whether whatever you build is realistic or curve-fitted. It's also useful as a plain-English glossary of the standard indicators before you go looking for a real edge elsewhere.

Skip it if

You already know the basic indicators and are looking for a tested, specific strategy with disclosed rules and results; this book explains the tools and the testing process but doesn't hand you a strategy that has been shown to work. Skip it too if you're trading a modern commission-free, largely electronic market and don't want to filter 2007-2008 market-structure commentary out of the advice.
