How to place a stop loss correctly (and where not to)
A stop loss goes at the point where, if price reaches it, your trade idea is proven wrong — not at a fixed "20 pips" distance nor where "you only lose a little". It's the most important order you'll place, because it defines your risk before the market gets a say. And almost every beginner places it backwards: they first decide how much they want to lose, then put the stop there, instead of letting the chart's structure decide.
The golden rule: the chart decides the stop, not your wallet
Your trade rests on an idea: "price will rise from this support". That idea has an exact point where it stops being true: if price clearly breaks the support, your reason for being in has vanished. That's where the stop goes — a little below that level. If the "correct" stop is far away and the trade feels too big, the answer isn't to tighten the stop: it's to reduce position size (or not trade). Tightening the stop to risk less guarantees that normal market noise takes you out, while you were right on direction.
Method 1: structure stop
The most used and most logical. You place the stop on the other side of the level supporting your idea:
- Buy at support: stop just below the support (plus a small margin for noise).
- Sell at resistance: stop just above the resistance.
- Breakout: stop below the breakout zone, where a move back would confirm it was false.
The advantage: your stop has meaning. It doesn't get hit by a random move, only when the market is telling you you were wrong.
Method 2: ATR stop (volatility)
The ATR measures how much an asset moves on average. A stop of 1.5 to 2 times the ATR sits outside that asset's normal "noise", adapting to its volatility. It's especially useful on Gold, which moves a lot: a stop designed for EUR/USD would be absurdly small for XAUUSD. The logic is the same as always — give the trade room to breathe — but calculated with an objective number instead of by eye.
The three mistakes that blow up accounts
| Mistake | Why it's fatal |
|---|---|
| "Penny" stops | So tight that normal noise takes you out again and again, while right on direction |
| Moving the stop against you | Widening it when the trade goes bad turns a controlled loss into a catastrophe |
| Trading without a stop | "I'll close it by hand if it goes wrong" — until a sharp move takes half your account |
The stop is sacred: decided beforehand and not renegotiated
The time to decide the stop is before entering, cold. Once in, your emotional self will hunt for excuses to move it ("it'll surely bounce", "I'll give it a bit more"). That's exactly the mechanism that ruins accounts: cutting winners fast and letting losers run. Discipline is boring and it works — the stop is placed, and if it's hit, it was hit. Your cold self sets the rules; your hot self only executes them.
The stop is one leg of risk management; the other is how much you risk on each trade. You have it in the 1% rule explained with numbers. And to understand why management matters more than analysis, read why 90% of traders lose money.
