Trend

Mechanism

A trend EA reads a moving-average crossover, ATR-band breakout, or momentum oscillator to enter in the direction of the prevailing move, then trails its stop-loss as price runs. Exits trigger on signal reversal or trail-stop hit. Position size is fixed or scaled to ATR. Trade frequency is low (= 5-30 per month per pair) compared to scalping or grid.

Suitability

Best in markets with sustained directional momentum (= EUR/USD H1 during London session, USD/JPY trending weeks, XAU/USD in macro themes). Poorly suited to range-bound consolidation, where false breakouts produce repeated small losses. Capital tolerance ~5-15% drawdown realistic; suitable for traders who can hold positions for hours-to-days without intervention.

Notes

Trend-following is the original systematic edge in markets — turtles in the 1980s, managed-futures programmes since the 1970s, currency-overlay funds today. The mechanism survives because it monetises a behavioural fact: persistent directional moves last longer than mean-reversion expectations imply, and the patient holder gets paid by the impatient trader who keeps fading the move.

For the EA-running retail trader, the trade-off is psychological: you accept losing 60-65% of trades and recoup the difference on the 5-10% that compound into multiples-of-risk gains. This is the opposite emotional shape of a scalper’s “win often, lose rarely” profile, and many users abandon trend systems after a six-trade losing streak — even when the underlying expectancy remains intact.

When evaluating a trend EA on this catalogue, the metrics that matter:

1. Maximum drawdown over a 5-year backtest — must be tolerable through a real losing streak, not just on paper.
2. Recovery time from drawdown trough to new equity high — long recoveries (90+ days) test discipline.
3. CAGR / max-DD ratio — a trend EA targeting 18% CAGR with -8% max DD has a much higher quality-of-edge than 18% CAGR with -20% max DD.
4. Trade frequency — too few trades (= < 5/month) and the sample size is too small for a statistical claim about the edge.
