Trend-following EAs enter in the direction of an established move and stay in while it lasts. The shape of the record — win rate, payoff ratio, streak length — comes from the exit rule, not the entry. That is why published trend EAs range from a 31% to a 79% win rate.

Scalping names a holding time, and the chart period does not predict it. Across the records published here the M15 EAs hold their median trade 65.77 hours while the H4 EAs hold 9.82, and every one of the fourteen is ended by a round-trip cost worth 7.63% to 27.04% of its average win.

Grid EAs open orders at regular price intervals, building a mesh of buy and sell entries that profits from oscillation. Capital-intensive; requires careful drawdown management to survive trending regimes.

Martingale EAs double position size after each loss so that one winner repays the whole run. Replayed over 9,339 published trades, the ladder closes 100% of its cycles at a profit on every record and still consumes a 10,000 deposit on four of the fourteen. Doubling repays only where the average win is at least the average loss, which is true of six.

Arbitrage EAs exploit temporary price discrepancies between related instruments. Latency-sensitive and broker-dependent. Retail variants use statistical correlation rather than pure cross-exchange arbitrage.

News EAs trade the volatility spike around scheduled economic releases — a straddle before the event, or a blackout filter that suppresses entries around it. High variance and brutally spread-sensitive; a Raw/ECN account is mandatory for the straddle variant.

Mean-reversion EAs enter against a move once price has stretched a measured distance from its average, and target the return. The label describes the entry only. Across the six published here, win rate runs from 40.26% to 79.17% and payoff ratio by a factor of six — yet all six profit factors land between 1.25 and 1.50.

Breakout EAs enter when price exits a defined consolidation range or key level with momentum confirmation. Higher entry quality than pure trend signals, but vulnerable to false breakouts in low-volatility markets.
