Exp_STLMCandle
This EA trades based on signals from the custom STLMCandle indicator, opening buy positions when the indicator signals bullish momentum and sell positions on bearish momentum. It uses a Jurik-style smoothed indicator (JLength/JPhase parameters) to determine trend direction from candle color states. Entry and exit are controlled by separate boolean flags, allowing selective enablement of long/short opening and closing.

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 strategy concept is based on the STLMCandle custom indicator's color state to determine trend direction, where indicator buffer 4 returns color values: 2 for uptrend and 0 for downtrend. Entry conditions: when Clr[1]==2 and Clr[0]<2, a buy signal is triggered; when Clr[1]==0 and Clr[0]>0, a sell signal is triggered, which detects color state transitions as trend reversal confirmations. Exit conditions: opposite trend signals automatically close existing positions, with buy signals closing sell positions and sell signals closing buy positions. Position sizing supports multiple modes through the MMMode parameter, including fixed lot size, percentage of balance, percentage of free margin, and percentage of loss-adjusted margin. Money management uses fixed stop loss and take profit with defaults of 1000 and 2000 points respectively, yielding a risk-reward ratio of 1:2. The strategy only recalculates signals on new bar formation using the CIsNewBar class, avoiding redundant per-tick computation and improving efficiency.
Strengths
- Clear strategy logic based on trend reversal signals, aligning with trend following principles
- Multiple position sizing modes offering flexibility for different risk preferences
- Independent entry and exit signal controls allow selective enablement of buy/sell directions
- New bar detection mechanism prevents duplicate signals and reduces invalid trades
- Stop loss to take profit ratio of 1:2 provides a positive expectancy risk-reward design
Weaknesses
- Depends on the custom STLMCandle indicator whose internal logic is opaque, making signal reliability hard to verify
- No spread filter mechanism, which may cause unnecessary losses in high-spread environments
- No maximum position count limit, potentially leading to over-trading in choppy markets
- Fixed stop loss and take profit do not account for market volatility (ATR), reducing adaptability across different conditions
- Lacks drawdown control and maximum loss limits, leaving risk uncontrolled in extreme market scenarios
Possible improvements
- Add ATR-based dynamic stop loss and take profit to automatically adjust distances based on market volatility
- Implement spread filtering and maximum position count limits to reduce trading frequency under adverse conditions
Risk assessment
Overall risk: Medium
- No maximum drawdown limit, lacking automatic protection during consecutive losses
- Custom indicator black-box nature makes it difficult to diagnose and adjust when signals fail
- No spread filter, stop losses may be severely penetrated in high-slippage environments
