Stop-loss placement
Where the stop goes decides everything
Read
Your stop is not a safety net you add at the end. It is the first decision of the trade — it sets your risk, your size and your reward-to-risk before you have entered anything.
AI Mentor here. 🧠 Most traders treat the stop-loss as paperwork: pick the trade, then drop a stop somewhere underneath it. Backwards. The stop is the price at which you admit the idea was wrong — so it defines what the trade actually risks, how large it can be, and whether the reward is worth taking at all.
And it has to be decided before you enter, while your head is clear. Afterwards you will have a position, an opinion and a P&L number pulling at you, and none of those three are good analysts.
You choose your loss at the moment you enter, by where you put the stop. The only question is whether you choose it on purpose.
Place it where you are wrong
A good stop sits at a level which, if price reaches it, proves the trade idea failed. Not at a round number, not at "how much I feel like losing" — beyond a piece of structure the market should respect if you are right.
For a long, that usually means below support: under the level that was supposed to hold. For a short, above resistance: over the level that was supposed to cap price. In both cases, place it *beyond the wick* — past the swing high or low rather than sitting exactly on it, where every other obvious stop is parked.
Markets wiggle even when they are behaving. Account for normal noise — a measure like ATR is a good guide — so ordinary volatility cannot tag your stop on a day when nothing actually went wrong.
Structure first, then size
This is the sequence that separates professionals from everyone else, and it only has three steps.
First, find where the stop logically belongs — beyond structure, from the chart. Second, measure that distance. Third, choose a position size so that if the stop is hit, the dollar loss is only 1–2% of the account.
The distance comes from the market. The size adjusts to fit it. A wide stop means a smaller position, and that is not a problem to be solved — it is the answer working correctly.
Never do it backwards. Never widen a stop so a bigger position "fits", and never move a stop further away because price is approaching it. That is not risk management — it is deciding to take an unlimited loss instead of a planned one.
Trailing to protect profit
Once a trade moves your way, the stop can start working for you instead of just against the downside. Trailing means moving it up behind a long as price advances.
The usual first move is to breakeven — from that point the trade cannot cost you anything. After that, trail behind each new higher low rather than at a fixed distance, so the stop stays anchored to structure the way it was at entry.
It lets a winner keep running while making sure a reversal cannot turn a good trade into a losing one. The cost is that you will sometimes be stopped out of a trade that later goes further. That is the price, and it is worth paying.
Decide the stop first, size to it, then trail it. Do that and the worst day you can have is a day you already agreed to. 🛡️
