ATR Trailing Stop Backtest in Crypto: Fees, Slippage and Break-Even Costs

An ATR trailing stop exits when price falls a multiple of ATR from its high. In a backtest, how the stop is triggered and filled inside each bar decides the result.

Short answer

An ATR trailing stop sets an exit at highest price since entry minus k × ATR (for longs). Backtests must decide whether the stop uses intrabar highs and lows or closes, and how the stop fills: in fast drops, a stop-market order fills below the trigger. Using closes delays exits; using intrabar extremes with no slippage flatters results. Model stop fills with slippage, update the trail only on closed bars and report how results change with k.
