A fixed number of pips — "always use a 20-pip stop" — is an easy rule to follow and a poor one to trade with, because it ignores the two things that should actually determine stop placement: current volatility and market structure. The same 20 pips means something completely different on a quiet session than during a news-driven trend day.
Structure-Based Placement
A stop placed just beyond a recent swing high or low, or beyond a clear support/resistance zone, is placed where the trade's premise is actually invalidated — not at an arbitrary distance. If price reaches that level, it means the specific reason you entered the trade no longer holds, which is a more defensible reason to exit than "I've lost a preset number of pips."
Volatility-Based Placement
The Average True Range (ATR) indicator gives a rolling measure of how much a market typically moves in a given period. A stop set at a small multiple of current ATR (commonly 1.5-2×) automatically adjusts to conditions — wider during volatile stretches, tighter during quiet ones — rather than staying static regardless of what the market is actually doing.
- A fixed-pip stop gets you stopped out on normal noise during volatile periods, and leaves too much on the table during quiet ones
- Combine structure and volatility where possible: place the stop beyond the relevant structural level, then sanity-check the distance against current ATR
- Position size should be calculated after the stop distance is set — not the other way around
The goal isn't a "correct" universal stop distance — there isn't one. It's a stop that reflects why you're in the trade and what current conditions actually look like, recalculated setup by setup rather than set once and reused everywhere.
