ADX Trend Filter Backtest in Crypto: Fees, Slippage and Break-Even Costs
An ADX filter lets a strategy trade only when trend strength is above a threshold. It removes some chop and delays entries.
Short answer
An ADX trend filter allows entries only when ADX is above a threshold (often 20–25). Because ADX is double-smoothed, it rises after a trend is underway, so the filter removes some range trades but also delays entries into new trends. Compare the base strategy with and without the filter on break-even cost, trade count and profit share from the largest trends, and test the threshold as a parameter. Use closed-bar ADX values to match history.
Break-even cost
| Item | Value (illustrative) |
|---|---|
| Trades | 150 |
| Gross avg per trade | +0.44% |
| Fees (2 × 0.05%) | −0.10% |
| Slippage (2 × 0.03%) | −0.06% |
| Net avg per trade | +0.28% |
| Break-even round-trip cost | 0.44% |
With vs without the filter
| Version | Trades | Gross avg | Net avg (illustrative) |
|---|---|---|---|
| No filter | 320 | +0.20% | +0.06% |
| ADX > 25 | 150 | +0.44% | +0.30% |
| ADX > 35 | 60 | +0.52% | +0.38% (few trades) |
