STOP-LOSS RULES THAT ACTUALLY WORK
Most retail stops are placed at round numbers and obvious levels — exactly where institutional algorithms hunt for liquidity. Better stops save more accounts than better entries do.
A stop-loss is the price at which you admit you were wrong and exit. The math is simple: lose 50% and you need a 100% gain to break even. Lose 90% and you need a 900% gain. Survival is not optional.
The most common bad stop is a round number ($100, $50, $20). The second most common bad stop is exactly at the previous swing low. Both are visible to every algorithm scanning order books and both will get triggered routinely on noise alone before the trade has a chance to work.
Better placement uses a structural reference plus a volatility buffer. Find the most recent meaningful swing low (or high for shorts), then add 1× ATR (Average True Range) below it. The volatility buffer means random noise won't take you out, but a real break of structure will. Your position size is then calculated from this stop distance, not the other way around.
Trailing stops should follow structure, not a fixed dollar amount. As price makes new higher highs and higher lows, trail the stop to just below each new higher low. You'll give back some open profit on the final reversal, but you'll capture the meat of the move and avoid being shaken out mid-trend.
Takeaways
- →Never place stops at round numbers or the obvious previous low.
- →Stop = structural level + 1× ATR buffer.
- →Size the position from the stop, not the stop from the position size.
- →Trail stops on structure (new higher lows), not dollar amounts.
