Scalping

Mechanism

A scalping EA opens and closes positions within minutes — typically 1-15 bars on M1 or M5 — targeting a small pip profit per trade. Entry signals are fast-oscillator extremes, micro-structure order-flow patterns, or bid/ask spread rebound. The EA fires many orders (50-200/month) and relies on statistical edge across volume, not large per-trade gains.

Suitability

Best in dense-liquidity windows: London open (07-10 UTC) and NY-London overlap (12-16 UTC) on EUR/USD, GBP/USD, and USD/JPY. Unsuitable for brokers with market-maker execution or variable spreads that widen during news. Requires Raw/ECN account with commission ≤ $7/lot round-turn. Expect tight equity drawdown (<5%) punctuated by fast recovery cycles.

Notes

Scalping is a volume game, not a per-trade one. The EA opens and closes within minutes, taking two to eight pips at a time, and relies on a small statistical edge repeated across fifty to two hundred trades a month rather than on any single large win. Because each trade’s profit is tiny, the cost of trading — spread, commission, slippage — is not a footnote; it is the whole contest.

That makes execution quality the dominant variable. A scalper that is profitable on a Raw/ECN account with sub-pip spreads and low latency can be net-negative on a market-maker account whose spread widens at exactly the wrong moments. A co-located VPS near the broker’s servers, dense-liquidity windows (the London open and the NY-London overlap), and a commission of seven dollars per lot or less are not optional extras — they are the strategy.

When evaluating a scalping EA on this catalogue:

1. Broker and account type — Raw/ECN with tight commission; market-maker execution usually breaks it.
2. Latency / VPS — measured execution speed matters more than for any slower strategy.
3. Net-of-cost expectancy — judge results after spread and commission, never before.
4. Session filter — does it trade only in the high-liquidity windows where the edge exists?
