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
E-Friday's strategy concept is based on Friday-specific market behavior patterns, exploiting price volatility driven by pre-weekend liquidity changes and position adjustments by institutional traders. Entry conditions typically include Friday session momentum signals, moving average crossovers, or support/resistance level breakouts, with some versions incorporating volatility filters to confirm trade opportunities. Exit conditions may use fixed take-profit and stop-loss levels, Monday open closing, or trailing stops, with the core logic aimed at capturing profits from weekend position adjustments and Monday opening gaps. Position sizing offers both fixed lot and equity-based dynamic calculation modes, though specific parameters depend on version configuration. Money management typically employs a percentage risk model or fixed lot approach, with some versions including maximum position limits and trading pause mechanisms after consecutive losses. The strategy's key assumption is that predictable price behavior exists between Friday's close and Monday's open, but this assumption can fail during sudden liquidity shocks or major news events.
Strengths
- Exploits Friday-specific session effects with a statistically verifiable intraday pattern foundation
- Trading hours are clearly limited, preventing unintended entries during off-hours and reducing overtrading risk
- Weekend gap logic provides clear holding period and profit assumptions for the strategy
- Parameterized design allows users to adjust the strategy for different instruments and market conditions
- Over-weekend holding logic complements intraday strategies, providing a differentiated return source
Weaknesses
- Over-weekend positions face gap risk; Monday's opening price may deviate significantly from Friday's close, causing larger-than-expected losses
- The Friday session effect is not effective in all market conditions; trending markets or major news can completely alter weekend behavior patterns
- Lacks liquidity and spread filtering mechanisms, potentially encountering slippage and quote anomalies during low-liquidity Friday late sessions
- Strategy dependence on Friday-specific sessions means only one trading window per week, resulting in low opportunity frequency
- Over-weekend holding increases swap costs and uncontrollable black swan event risk exposure
Possible improvements
- Add economic calendar filtering for major weekend news events to avoid holding positions over high-risk weekends
- Introduce volatility-adaptive stop-loss and take-profit mechanisms using ATR-based dynamic risk parameters instead of fixed pip values
- Add Friday liquidity indicators and spread monitoring to automatically pause trading when liquidity is insufficient
Risk assessment
Overall risk: Caution
- Over-weekend positions face uncontrollable gap risk; Monday's open may show a large adverse gap opposite to the expected direction
- Declining Friday late-session liquidity may cause increased slippage and poor stop-loss execution
- Lacks major news event filtering, leaving risk exposure uncontrolled during weekend surprise events
