Volatility-managed strategies

These pair well-known entries with the risk toolkit — ATR (volatility) stops, trailing stops, time stops and risk-based position sizing — so the position adapts to how much the asset is actually moving instead of using a fixed percentage. The point isn't a different signal; it's letting a calm market breathe and cutting a wild one quickly, and sizing each trade to a consistent risk. More exit sensitivity isn't free, though — tighter stops cut winners short and tax turnover.

Each one below is a mechanism to test, not a recommendation. Open it to see exactly how it works in plain English, then backtest it yourself — costs on, no look-ahead, measured against buy & hold — or open it in the builder to tweak.The sparkline on each card is the strategy's performance relative to buy & hold — it only rises when the strategy is beating a passive hold.
