Overview
Jamesmaria EA employs an H1 entry strategy based on the EMA 21/50 crossover and RSI confirmation, using H4 trend filtering for higher-probability setups. The EA includes dynamic lot sizing scaled to account equity, ATR-based take profits, and a trailing stop. Risk management features include a daily percentage loss limit, a maximum spread filter, and a session filter for London and New York hours. While documentation suggests conservative settings, the code defaults to a high equity-based stop loss.
- H1 EMA crossover with H4 trend filter
- Equity-based dynamic lot scaling
- ATR-based trailing stop
- Daily percentage loss limit
- London and New York session filter
