There is an old image that captures this rule perfectly. A train is pulling out of the station, and you are standing on the platform having just missed it. You can sprint down the platform after it, jump for the last door as it accelerates away, and quite possibly fall under the wheels — or you can stand still, accept that this train has gone, and wait calmly for the next one, which is always coming. Every trader faces this choice constantly, and Rule No. 7 is simple: never run after the train. Wait for the next one.
This is one of the most important rules in the whole set, and it is also one of the hardest to obey, because it asks you to do nothing in a moment when every nerve in your body is screaming at you to act.
The trade you talked yourself into too late
Here is how it traps even experienced traders. You have done your homework and you have a view: the market should rise today. You watch, waiting for your entry. And then it begins to rise — exactly as you predicted. But you hesitate. You want a slightly better price, or you are not quite sure, and the moment passes without you. The market ticks up, and now you feel the first sting of regret: I was right, and I'm not in it.
It keeps going. Twenty points, fifty, a hundred, climbing steadily away from you. With every point, the regret sharpens into something closer to anger — anger at yourself for missing a move you correctly called. You watch the train pull out of the station and accelerate down the track, and the longer you watch it run, the more unbearable standing on the platform becomes.
And then, finally, frustration wins. You cannot stand to miss another point. You jump — you buy, late, well after the move has run, chasing the price that has already left you behind. And in the very moment you enter, the market does the thing it does so reliably to latecomers: it turns. It rolls over and falls, and because you entered in a flush of emotion rather than a moment of analysis, you almost certainly did not set a stop. The loss runs, and runs, and the move you spent all morning admiring from the sidelines finally pays you — by taking your money on the way back down.
That is chasing the market, and it is one of the most expensive habits a trader can have.
Why the late entry is the worst entry
This is not bad luck. The chaser gets punished systematically, for reasons rooted in how moves actually work.
A move that has already run a long way is, by definition, closer to its end than its beginning. The traders who entered early — the ones who did their homework and were waiting at the station before the train left — are now sitting on good profits and starting to think about taking them. The energy that drove the move is being spent. And the very last buyers to arrive are precisely the frustrated latecomers, the people who held out as long as they could and then capitulated and piled in at the top. When the last reluctant buyer has finally bought, there is no one left to push the price higher. That is the moment the move reverses — and the chaser, having bought at the very top, is left holding the position as the early traders sell their profits to him.
So the chaser does not just enter at a bad price. He enters at the single worst price, for a structural reason: his own frustration is the signal that the move is exhausted. The feeling that finally drives you into the trade is the same feeling driving every other latecomer, and the simultaneous arrival of all that frustrated money is what marks the top. Your emotion is, once again, a contrarian indicator — firing hardest at exactly the wrong moment, just as it did in the whipsaw of Rule No. 3.
And notice what the chase trade lacks. It has no thesis — "I should have been in this" is regret, not a reason. It has no planned entry level — you bought wherever the price happened to be when you cracked. And it usually has no stop, because a trade entered on impulse skips the discipline of Rule No. 6 entirely. It is a position with none of the things a position is supposed to have. It is pure emotion wearing the costume of a trade.
A missed profit is not a loss
The cure begins with a single shift in how you see a missed move, and it is the shift most beginners never make.
When the market runs without you, you have not lost anything. You have exactly the same capital you had before. A missed profit is not a loss — it is simply a gain you did not happen to capture, and there will be thousands more of them in your career. The chaser feels the missed move as though money has been taken from him, and it is that false sense of loss that drives him to "win it back" by jumping in late. But nothing was taken. The only way to actually turn that missed move into a real loss is to chase it. Standing on the platform costs you nothing. Running after the train is the only thing that can hurt you.
Once you genuinely internalise that missing a trade is a non-event, the compulsion loses its grip. You can watch a move run away without you and feel nothing more than mild, passing regret, because you understand that another setup is always coming. The market opens again tomorrow. There is no such thing as the last trade.
Patience is the skill
This is where the great traders separate themselves, and the lesson runs all through Jack Schwager's Market Wizards, the collection of interviews with America's most successful traders. Read those interviews and a theme appears again and again: the best traders do not trade constantly. They wait. They sit, sometimes for hours, sometimes for days, doing nothing at all, until a setup arrives that genuinely meets their conditions. They have learned that there is no obligation to have a position, and that the discipline of waiting is not idleness — it is the job.
You will sometimes sit in front of the screen for four or five hours without taking a single trade. To a beginner this feels like failure, like wasted time, like you are "not really trading." It is the opposite. Choosing not to trade when there is no good trade is one of the most profitable decisions you can make, precisely because it keeps you out of the bad, chased, forced trades that do the damage. Being in cash, holding no position, is itself a position — and very often it is the correct one. The patience to hold it is a skill, and like any skill it has to be learned and practised, against every instinct telling you that action equals progress.
The discipline in practice
So what do you actually do when you miss the move? You return to the platform and wait for the next train. Concretely, that means you let the move go without acting, and you watch for the next legitimate opportunity it offers — often a pullback, where the market pauses and retraces part of the run, giving you a sane entry with a defined risk. Or you wait for the entirely separate setup that your homework flagged for later. Either way, you only enter when you have what a real trade requires: a clear reason and a predefined stop. If those two things are not present, you do not have a trade. You have an urge, and urges are not to be acted on.
The bottom line
Never chase the market. When a move runs without you, let it go — a missed profit is not a loss, and the only way to convert it into a real one is to jump in late, at the top, on emotion, where the market turns and punishes you. Wait for the next train. Sit on your hands for hours if you must, take no position when there is no good position, and understand that patience is not the absence of trading but the foundation of it.
The trains keep coming. Your job is not to catch every one. It is to be standing safely on the platform, calm and ready, when the right one finally pulls in.
