Exp_Delta_WPR
This EA trades based on the delta (change) of the Williams' Percent Range (WPR) indicator, entering positions when the momentum shift of WPR exceeds a threshold. It uses fixed lot sizing with stop loss and take profit for trade management.

Why this EA never traded: no entry rule survived the conversion.
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 core concept of this strategy is to capture sudden shifts in market momentum by measuring the rate of change (Delta) of the WPR indicator, rather than using traditional overbought/oversold zones. Entry conditions trigger when the WPR Delta exceeds a predefined threshold, signaling a significant momentum shift, at which point the EA opens a position in the direction of the shift. Exit conditions rely on fixed stop loss and take profit levels in points, with no trailing stop or dynamic exit mechanism. Position sizing uses a fixed lot approach without dynamic adjustment based on account equity or market volatility. Money management is relatively simplistic, relying solely on stop loss for per-trade risk control, lacking overall account-level safeguards such as maximum drawdown limits or consecutive loss protection.
Strengths
- Using momentum rate of change rather than static thresholds can capture trend turning points earlier
- WPR indicator is computationally simple and efficient with low execution latency
- Fixed stop loss and take profit provide a clear risk-reward ratio control
Weaknesses
- Fixed lot sizing does not adapt to account size changes, making money management inflexible
- Lack of trailing stop mechanism may cause premature exits and missed profits in trending markets
- Single-indicator strategy prone to frequent false signals in ranging markets leading to consecutive losses
Possible improvements
- Add dynamic position sizing based on account equity percentage or ATR for better capital allocation
- Implement trailing stop functionality to lock in more profits during trending moves
- Add multi-timeframe confirmation or supplementary indicator filters to reduce false signals in ranging markets
Risk assessment
Overall risk: Medium
- Fixed lot size may pose excessive per-trade risk on large accounts
- Lack of maximum position limit and consecutive loss protection mechanism
- Single indicator reliability diminishes significantly in non-trending market conditions
