Scaling Targets to the Current Range Instead of a Fixed Pip Count
Posted: Wed Oct 28, 2026 12:17 am
A fixed target of a handful of pips behaves very differently across regimes. In a quiet session, it may represent a large fraction of the typical range and take a long time to reach. In a fast session, it may be reached in seconds, with the stop sitting equally close to routine noise.
Range-scaled targets address this by expressing both target and stop as multiples of a recent volatility measure, such as average true range over a short window. When the measure doubles, distances double, and position size shrinks accordingly so that monetary risk stays steady. When the measure halves, the reverse holds.
The approach has trade-offs. Volatility measures lag, so a sudden expansion leaves targets too small for a moment, while a sharp contraction leaves them too wide. Window length matters: a short window adapts quickly but is noisy, and a long one is stable but slow. Spreads are also roughly fixed in pips, so when distances shrink in quiet markets, costs consume a bigger share of every trade and may make a setup unviable.
A sensible check compares the spread with the scaled stop distance before entry. If the ratio turns unfavourable, the correct response may be to skip the trade rather than tighten the numbers further.
