Competing outcomes
A trade may hit stop, target, time exit, or neither. Treating only stop survival ignores the economic endpoint.
Any stop can be made harder to hit by moving it farther away. The research question is whether a complete risk-adjusted strategy improves after size, target, cost, and holding consequences are included.
A stop-width curve is more informative than a single chosen distance because it exposes gradual stability or a suspicious historical sweet spot.
Survival is not profitability
FIELD 25A wider stop will mechanically survive more price movement, but survival alone says nothing about net expectancy. Stop distance changes position size, reward-to-risk, holding time, financing, and the set of entries that remain practical. A fixed pip width also represents different volatility across pairs and regimes.
Use volatility- or structure-normalised stop bins and hold account risk constant. For each bin, report stop probability, target probability, time exit, realised net R, drawdown, MAE and MFE. Choose the policy on development data and verify it later rather than selecting the most flattering survival percentage.
A trade may hit stop, target, time exit, or neither. Treating only stop survival ignores the economic endpoint.
Express distance as ATR fraction, prior range, structural invalidation, or return volatility so periods and instruments are comparable.
Keep planned account loss constant as stop width changes and include minimum-lot rounding and transaction costs.
The best stop loss is an invalidation and risk policy, not the width that avoids the most historical losses.
Generate one entry set without reference to future outcomes. Specify stop distances as fixed pips only when instruments and regimes are homogeneous; otherwise use ATR, prior range, or structural distance. Predeclare all bins.
For every width, adjust size to equal account risk, apply lot rounding, spread, commission, slippage and financing, and specify target and time-exit behaviour. Report stop, target, and time-exit incidence with net R, MAE, MFE, duration, and drawdown.
Prefer a stable region supported by a market or risk rationale, not the single historical maximum. Account for the widths and instruments tested, then confirm the chosen rule on later dates and stressed costs.
