Mark Douglas’s first book: the trap that turns traders into passive losers, his two rules for losses, and the seven steps to trading without fear

Published: 26 October 2026 · By Spencer Li, CFTe

What is The Disciplined Trader about? Mark Douglas’s 1990 book argues that self-discipline is a skill you learn, rather than a trait you are born with. He calls it “a specific thought methodology, a mental resource.”

A gambling game ends on its own and caps your loss at the bet. A trade does neither, so a trader who freezes keeps losing without lifting a finger. Fear makes it worse, because it narrows what you can see. Douglas’s answer is a programme of seven steps, built on two rules: define the loss before you enter, and take it the moment it shows up. Thinking in probabilities, the idea he is best known for, only arrives at step five.

Who is Mark Douglas?

Douglas was selling commercial insurance outside Detroit when he moved to Chicago in June 1981 to trade. He joined Merrill Lynch Commodities at the Chicago Board of Trade, “its second largest commodity office, with 38 account executives.” By his count, the typical customer there “lost his original stake within an average of four months.”

He had wiped out his trading account twice before the move. By March 1982 he had filed for bankruptcy, “a mere eight months after moving to Chicago.”

By June 1982 he was making steady money for his customers, and that summer he started this book. His summary of how losing traders turn it around: “the markets didn’t change, the tools that were used didn’t change, the trader did.” He founded Trading Behavior Dynamics in 1983. Trading in the Zone followed in 2000.

I first read Douglas around 2008, while at university, and The Disciplined Trader was the book.

How is it different from Trading in the Zone?

Our Trading in the Zone summary covers the five fundamental truths and the 20-trade exercise. Neither is in this book. The earlier book covers three things the sequel mostly leaves out.

• How a belief changes, with writing drills to drain the old one.
• How price moves, with support and resistance as traders’ beliefs.
• The order of learning, with probabilities fifth.

A trader on Reddit asked this year for psychology books that “actually improved your discipline,” and named both. They pair well. Trading in the Zone is about the market. The Disciplined Trader is about you.

What are the 10 key ideas at a glance?

Why does the market turn traders into passive losers?

This is the book’s most original argument, and it starts with gambling. Take a hand of blackjack. You choose to play and bet before the cards come out. The hand ends by the rules, and you can lose only the chips on the table.

A trade removes every one of those guard rails. Douglas puts it plainly: “Once you put on a trade, you have to actively participate to end your losses. You don’t need to do anything to continue to lose.”

That is the real job of a stop loss. It puts back the rule the casino gave you for free.

One unplanned loss then sets up the next mistake. Say you meant to risk 5 ticks and lost 20. That is a 4R loss (R is the amount you planned to risk). Now a 10-tick winner shows up, worth 2R. If you are trying to win back the last trade, Douglas says, “You will need at least 15 and preferably 20 to make you whole.” So you hold on too long. Revenge “only allows you to get back at yourself.”

Why does fear make you cut winners and run losers?

It is easy to scold yourself for this. Douglas explains it. Fear pins your attention on whatever feels threatening, or safe, and the rest drops out of view.

In a losing trade, the scared trader watches the comforting signs and waits for break-even. In a winning trade, he watches only what he could lose, so he grabs a small profit. Douglas calls this “an example of why the vast majority of traders cut their profits short and let their losses run.”

The key line: “Fear causes us to act without a perception of choice.” If you cannot see that you are wrong, you cannot choose to cut the loss. So his cure is rules you trust yourself to follow.

What are the seven steps to success?

Chapter 16 is the practical core. “Self-discipline is simply a mental technique to stay focused on what you need to learn, or do, to accomplish your goals,” Douglas writes. The seven steps are what to stay focused on.

1. Stay focused on what you need to learn. Set aside some capital “as tuition for your education.”
2. Deal with losses. His two trading rules live here.
3. Become an expert at one market behaviour. “More is not better,” he warns.
4. Learn to execute a trading system flawlessly. Take every signal, exits included.
5. Learn to think in probabilities. Trade with whichever side is winning, buyers or sellers.
6. Learn to be objective. Make “uncommitted assessments of the probabilities.”
7. Learn to monitor yourself. In a trade, keep asking whether anything “has to happen.”

What are Douglas’s two rules for losses?

Step two holds the only two numbered rules in the book.

Trading Rule 1: “Predefine what a loss is in every potential trade.”

Trading Rule 2: “Execute your losing trades immediately upon perception that they exist.”

To predefine a loss, ask one question before entry: “For this trade to be valid or continue to be valid, the market shouldn’t trade to what point?” If the distance to that point is more than you can stand to lose, then “don’t take the trade regardless of how much potential you think it might have.”

The self-check: “If you find yourself considering, weighing, or judging,” you have skipped a rule.

Why do traders abandon systems that work?

Because they want certainty. Traders see themselves as risk takers, Douglas writes, “but what they really want is a guaranteed outcome with some momentary suspense.”

Then comes his most useful number. “Rarely will the typical trader stay with his system beyond two or three losses in a row,” he notes, yet a streak like that “is a very common occurrence for most trading systems.” Run the sum. At 1% risk a trade, three losses in a row cost about 3%. That is routine for a system, and it is still where most traders walk away.

His drill: buy a simple system, so you are not tempted to tinker. Trade it with your tuition money, “keep your contract size light,” and take every signal until the rules feel like habit.

His bottom line is worth printing out: “As a trader it is more important to know that you will always follow your rules than it is to make money, because whatever money you make, you will inevitably lose back to the market if you can’t follow your rules.”

What does the book say about support and resistance?

Chapter 15 turns from the trader to the market. Douglas treats price levels as shared memories. A level holds because enough traders remember the market turned there, and act on it. “All beliefs eventually become self-fulfilling prophecies,” he writes.

That is why old resistance becomes support. Traders who sold there and got burned will not sell there again, and those still short buy back near break-even. Our post on when resistance becomes support shows the flip on a chart.

Where the human edge comes in

A platform can scan for your setup and place the stop. It cannot make you leave that stop alone, or take the fourth signal after three losses. That gap is this book’s subject.

Douglas sums it up in one line: “It isn’t you against the markets, it’s just you.” Discipline is the second of the Five Edges no scanner can trade for you, and The Disciplined Trader is a manual for building it.

What are the book’s weak spots?

Douglas is upfront about the first one: “I do not offer a trading system in this book.” Read it alongside a method that gives you an edge.

Chapter 9 describes memories as energy moving at the speed of light. None of the later rules depend on it, so you can skim it. The worked trades come from the 1990 bond pit, so take the reasoning and leave the numbers. As Douglas says, “Each circumstance will be different.”

When should you read The Disciplined Trader?

After some live trades. As I wrote in my reading list, “Read the psychology books last, because they only make sense once you have felt the emotions they describe.” This book sits in that list’s psychology section. Come to it when you keep breaking rules you already believe in. For the rest of the shelf, see the best investing and trading books of all time.

Concluding thoughts

The Disciplined Trader will not hand you a setup. It explains why you break the rules of the one you have. The passive-loser argument alone makes it worth reading.

So here is Douglas’s test for your next trade. Before you enter, can you name the price where the trade stops being valid, and would you take that loss without a second thought?

FAQ

What is the main idea of The Disciplined Trader?

That self-discipline is a mental skill you can learn, through a seven-step programme.

What are Mark Douglas’s two trading rules?

Predefine what a loss is in every potential trade, and execute your losing trades immediately upon perception that they exist. Both sit in Step Two, “Dealing with Losses.”

What is a passive loser in trading?

It is Douglas’s term for a trader who sits in a losing position and does nothing. A gambling game ends on its own and caps the loss at the bet. A trade stays open until you close it.

How Volman reads the 5-minute chart: the buildup test, five setups, a fixed 1:2 bracket, and the trades he skips

Published: 22 October 2026 · By Spencer Li, CFTe

Every breakout trader knows the feeling. Price pokes through a level, you buy, and ten minutes later the stop is gone.

Understanding Price Action, Bob Volman’s 2014 book, is about telling those breaks apart before you take them. He trades the 5-minute EUR/USD chart with plain bars and one moving average. His answer fits in three words: “conditions are king.” A break is worth taking when bars have fought at the level first, when it runs with the side in control, and when nothing blocks the road to target. The rest he skips.

The book turns that into seven principles, five setups and one fixed exit, a 20 pip target against a 10 pip stop. Then it spends close to half its length on six months of annotated sessions.

Who is Bob Volman?

In the book’s own words, Volman is “an independent trader working solely for his own account.” He was born in 1961. His first book, Forex Price Action Scalping, came out in 2011. This is his second, signed off in July 2014. The book prints no track record and no win rate.

How is it different from Forex Price Action Scalping?

Our summary of Volman’s first book, Forex Price Action Scalping covers a very fast 70-tick chart. Readers kept asking whether its ideas worked on slower charts. The Preface says yes, because the principles “bear within them the universal laws of supply and demand,” in futures, indices, stocks, commodities and bonds too.

So the changes are practical. The chart slows to 5 minutes, with a 25-bar exponential moving average as the one tool. The setups become a closed list of five. And Part 2 walks through 132 consecutive trading days from March to August 2012.

What are the 10 key ideas at a glance?

What does “conditions are king” mean in practice?

Imagine a level price has hit three times this morning. Now the bars shrink and huddle just under it, their highs tapping the same price. Volman calls that huddle buildup, and most of the book is about reading it.

The reason is who sits inside that cluster. Buyers are waiting to jump in on the break. Sellers who shorted the level have their stops just above it. When the barrier gives way, both groups buy at once, one out of greed and one out of fear. He calls it double pressure, and it is what carries a break far enough to pay.

A straight run that slices through the level has none of that. Nobody was trapped, and the nearest sensible stop is a long way off. His rule is short: “If we don’t find buildup there, the offer is best declined.”

So he grades every break three ways. A false break has no buildup and needs a wide stop. A tease break has buildup away from the barrier, and often works only “second time around.” A proper break comes out of a fight right at the barrier, so the stop can sit just behind the cluster.

A proper break can still fail, since “it is never the outcome that determines these labels.” In his words, “it is never about price, it is all about pressure.” Our guide to false breakouts runs the same test on daily charts.

What are the seven price action principles?

Chapter 2 lists seven: double pressure, support and resistance, false, tease and proper breaks, false highs and lows, pullback reversals, the ceiling test, and the round number effect.

The 25ema sits over all seven as a filter. “The 25ema by itself never provides support or resistance, it is just an average.” Price keeps returning to it, which “turns the average into a perpetual magnet,” so an entry far from it has that magnet pulling the wrong way. For one average on a slower chart, see the best indicators for swing trading.

What are the five trade setups?

Each setup fires the same way. A signal bar forms in the right spot, and the trade goes on when the next bar takes out its high or low “by a pip.”

1. Pattern break. A break out of a tight cluster at a barrier, often squeezed against the 25ema.
2. Pattern break pullback. The first break was missed or badly built, so you wait for price to return to the broken level.
3. Pattern break combi. A powerbar, then a small inside bar. Volman calls the pattern “just a tool with which to time an entry.”
4. Pullback reversal. An orderly pullback of roughly 50 to 60% that reaches the 25ema and turns.
5. Trade-for-failure. A break against the dominant side falls apart, and you trade the counterbreak with dominance.

The fifth looks contrarian, but it runs with the trend.

Why a fixed 20 pip target and a 10 pip stop?

Because the bracket takes the exit out of your hands. A trader prone to fear or greed, Volman says, “is probably better off putting faith in his bracket rather than in his own perceptions.”

A winner is +2R and a loser is -1R. Take 30 trades and say only 10 reach target:

10 winners × 2R = +20R, and 20 losers × 1R = -20R. You are flat.

Win 12 of the 30 and it becomes +24R against -18R, a gain of 6R. The selection rules only have to beat one winner in three.

The settings “do not claim to represent the ideal target and stop,” and in quiet markets he cuts the target to 8 to 10 pip. The habit underneath is deciding the exit before the entry, as in our guide on where to put your stop loss and take profit.

When does Volman say to skip a trade?

Far more often than he says to take one. Clear high-odds trades come “maybe once or twice a session in any one market.”

His seven typical errors make a pre-click check:

1. Trading against a strong trend.
2. Trading straight into support or resistance.
3. Mistaking a range for a trend.
4. Entering far from the 25ema, or near a round number.
5. Trading a frantic market of oversized bars.
6. Reversing a pullback full of aggressive powerbars.
7. Front-running a break with too little buildup.

Suppose you catch yourself counting bars to talk yourself into a trade. That effort is the answer: “if we have to look hard for a trade, it is probably not there.” On news he says to “shun the news rather than try to trade it,” and on EUR/USD he stands aside at 14:30 CET.

What does the book say about position size?

Chapter 10 calls sizing “an accounting matter.” You risk a fixed percentage on each trade, so size grows and shrinks with the account. He suggests 1 to 2%, and says “it is strongly advised not to risk more than 2 percent on a single wager.”

The shrinking half is what keeps an account alive. Every losing run is traded smaller, so he argues it is “virtually impossible to blow up an account” under the rule. Lose 1% on 20 trades in a row with size following the balance, and you are down about 18% rather than 20%. Our post on risk of ruin shows why bet size moves that number most.

Then he undercuts his own tables. A steady weekly score, he admits, is “virtually untenable in practice.” His advice: “Much more useful is to concentrate on improving consistency first.”

What does the book not tell you?

There is no win rate. Volman shows close to 400 charts but never totals the trades. Whether six months rules out cherry-picking can be argued, he grants, “but there is a limit to what a trading book can do.”

The charts are from 2012. By July 2014 he wrote of “record-low volatility” intraday and moved to a faster chart with smaller targets. So the 20/10 settings belong to a normally active market.

And there is no journal or scoring system. He asks you to backtest a year of data yourself.

Where the human edge comes in

Much of this book is easy to turn into rules. Distance from the 25ema, a round number inside your stop, a news release due, oversized bars. A scanner can flag all of them.

It cannot flag the rest. Is that cluster real buildup, or a dead market “trading into nothingness”? Is the pullback in proportion to the move before it, what Volman calls the harmony principle? He admits the line between a tease and a proper break “can be rather thin at times.”

His answer is study, a library in your head of situations “that you have seen fail or succeed many times before.” Then he warns against the belief that a repeating market can be called in advance. “It can’t. It can only be anticipated.”

The filters say when a trade is allowed. Turning down an allowed trade because the fight looks thin is a person’s judgement, built one session at a time.

Concluding thoughts

Understanding Price Action is a long book about one question: was this break built well enough to take? Volman answers with a short set of tests and a fixed exit, then shows hundreds of sessions where the tests decide.

So think back to your last three losing breakouts. Was there a fight at the level first, or did you buy a straight run into the barrier?

FAQ

What is Understanding Price Action by Bob Volman about?

It is a 2014 manual for trading breakouts on the 5-minute EUR/USD chart. Volman teaches you to judge the buildup before a break, trade with the dominant side, and exit on a fixed 20 pip target and 10 pip stop.

What moving average does Bob Volman use?

A 25-bar exponential moving average, the only tool on his chart. He uses it as a filter, never as support or resistance.

Does Volman’s method work outside forex?

He says the principles apply to futures, indices, stocks, commodities and bonds. The settings may need adjusting for each market’s range and speed.
