VR---ZVER
This EA implements a martingale-based trading strategy that doubles lot size after each losing trade while attempting to recover losses through progressively larger positions. It typically opens initial trades based on simple signal logic and then increases exposure on subsequent losses. The strategy carries significant risk of account depletion during extended losing streaks.

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: High
- Increases the position size after losses (martingale)
- Has no stop loss or trailing stop
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
This EA implements a classic martingale strategy concept, where the core idea is to double the lot size after each loss, expecting a single winning trade to recover all previous losses. Entry conditions are typically based on simple technical indicator signals or price action triggers, such as moving average crossovers or RSI overbought/oversold levels. Exit conditions primarily rely on closing positions once a profit target is reached, resetting to the initial lot size after a win. Position sizing follows a typical doubling pattern of 1-2-4-8-16... with no explicit maximum multiplier limit. Money management lacks effective maximum drawdown controls and stop-loss mechanisms, which could lead to account blow-up during extreme market conditions. The strategy may perform well in ranging markets but will suffer severe losses during strong trending conditions.
Strengths
- Can accumulate small profits in ranging markets, and short-term backtesting may appear favorable
- Strategy logic is simple and intuitive, easy to understand and adjust parameters
- With small initial lot sizes, it can withstand a certain number of consecutive losses
Weaknesses
- Martingale strategy causes exponentially growing positions during consecutive losses, potentially leading to account blow-up in extreme markets
- Lacks effective stop-loss mechanisms, unable to limit single or cumulative maximum losses
- Strategy does not distinguish market conditions, repeatedly adding counter-trend positions during trending markets causing severe losses
- Money management is unsound with no maximum drawdown protection measures
- Long-term mathematical expectation is negative, inevitably encountering unsustainable consecutive losses
Possible improvements
- Add maximum drawdown protection and forced stop-loss mechanism, limiting the maximum martingale multiplier levels
- Incorporate market regime detection (trending/ranging), only enabling martingale strategy during ranging markets
Risk assessment
Overall risk: Dangerous
- Martingale doubling strategy causes exponential position growth during consecutive losses, lack of upper limit control may lead to account blow-up
- No effective stop-loss mechanism, unlimited losses during extreme one-directional markets
- No maximum drawdown protection or money management threshold
