Converted from MQL5 to Python and run with the same rules for every EA. Positions use MT5 lot sizes (100,000 units per FX lot, 100 oz per gold lot) with 1:100 leverage, one order at a time, and a stop-out below 10% of the starting balance. Sharpe is computed from the equity curve. Results marked as unreliable are shown for completeness only.

Blow-up risk: No blow-up pattern found
None of the usual blow-up patterns were found in the code, and the account was not stopped out in our backtests. That is not a guarantee: any EA can lose money.
High: stopped out in our backtest, or martingale/grid sizing without a stop loss. Elevated: martingale or grid sizing with a stop loss, or several positions at once without a stop loss. What the label means and what we found →
Strategy analysis
The strategy concept is based on Elder Ray theory, measuring bullish and bearish forces to determine market dominance. Entry conditions: long positions are opened when Bulls Power is positive and rising, while short positions are opened when Bears Power is negative and falling, with EMA serving as the trend confirmation filter. Exit conditions include fixed stop loss and take profit levels, as well as indicator reversal signals for position closing. Position sizing employs either fixed lots or dynamic lot calculation based on account balance. Money management provides risk percentage parameters to control the risk exposure per trade. The overall strategy is a momentum-following type, suitable for markets with clear trending conditions.
Strengths
- Strategy based on classic Elder Ray theory with clear logic and theoretical support
- Bears/Bulls Power indicators intuitively reflect market buying/selling pressure with easy-to-understand signals
- EMA trend filter reduces false signals in ranging markets
- Offers both fixed and dynamic lot sizing for flexible position management
- Clear stop loss and take profit parameters provide controllable risk
Weaknesses
- Momentum strategy prone to frequent false signals and consecutive losses in ranging markets
- Lacks new bar check mechanism, potentially opening repeated positions on the same bar
- No spread filter, resulting in potentially high entry costs in high-spread environments
- Relies on single indicator combination without multi-dimensional confirmation
- Lacks trailing stop functionality, profitable positions may give back significant gains
Possible improvements
- Add new bar check mechanism to prevent repeated position opening on the same bar
- Add spread filter and volatility filter to improve entry quality
- Implement trailing stop functionality to protect floating profits
- Add multi-timeframe confirmation to improve signal reliability
- Add maximum consecutive loss limit and overall drawdown protection
Risk assessment
Overall risk: Medium
- Lacks new bar check, potentially opening multiple positions on the same bar leading to overexposure
- Momentum strategy may produce consecutive losses in ranging markets
- No spread filter, high spread environments may erode profits
