New Martin
New Martin is a Martingale-based Expert Advisor that opens trades and doubles the lot size after each consecutive loss, aiming to recover all previous losses with a single winning trade. It typically uses a simple directional entry signal and relies on the Martingale progression to achieve net profitability rather than high win-rate strategy logic. The EA carries significant risk of account drawdown or margin call during prolonged losing streaks.

Profitable on 3 of 4 markets with reliable results.
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.
Against the other Martingale EAs with a reliable result on the same market: EURUSD: better than 100% of 16 · GBPUSD: better than 67% of 15 · USDJPY: better than 94% of 16 · XAUUSD: better than 12% of 16

Blow-up risk: Elevated
- Increases the position size after losses (martingale)
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 the classic Martingale money management method, which doubles the lot size after each consecutive loss so that a single winning trade can recover all accumulated losses and produce a net profit. Entry conditions are typically simplistic, often relying on a single indicator signal such as a moving average crossover or price breakout, or even repeating entries in the same direction regardless of market conditions. Exit conditions primarily depend on a take-profit target that closes all positions when the cumulative loss is covered by a single win; some versions may include stop-losses but these are often weakened under the Martingale logic. Position sizing follows an exponential progression where lots grow by powers of two (e.g., 0.01, 0.02, 0.04, 0.08...), causing position sizes to balloon dramatically after a series of consecutive losses. Money management lacks effective protective mechanisms such as maximum drawdown limits or maximum step limits, which can lead to account liquidation during extreme market movements. The core risk of this strategy lies in the uncontrollable nature of losing streaks—when the market moves persistently against the position, account equity will decline rapidly until margin requirements can no longer be met.
Strengths
- Simple and intuitive logic that is easy to understand and adjust parameters for
- Higher probability of recovery after drawdowns in ranging markets, potentially good short-term performance
- Typically concise code structure that allows quick deployment and modification
Weaknesses
- Lot sizes grow exponentially during consecutive losses,easilyleading to margin calls and account blow-up
- Lacks effective market trend assessment, creating enormous risk from adding positions against the trend
- No maximum drawdown protection mechanism; account safety relies entirely on luck and market oscillation
Possible improvements
- Add a maximum drawdown percentage limit that stops adding positions and forces closure when the threshold is reached
- Incorporate trend filtering indicators (e.g., higher timeframe moving average or ADX) to avoid adding positions against the prevailing trend
- Set a maximum Martingale step limit that resets lot size instead of continuing to double beyond the threshold
Risk assessment
Overall risk: Dangerous
- Martingale doubling mechanism causes exponential lot growth during consecutive losses, posing margin call risk
- No effective stop-loss mechanism means losses can expand indefinitely until margin is exhausted
- Counter-trend position adding strategy will suffer catastrophic losses in sustained trending markets
