Fibo iSAR
This EA combines Fibonacci retracement levels with the Parabolic SAR indicator (iSAR) to identify trend-following entry opportunities. It opens trades when price aligns with key Fibonacci levels and the Parabolic SAR confirms trend direction. The strategy aims to capture trend continuations after pullbacks to Fibonacci zones.

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 strategy of this EA combines Fibonacci retracement levels with the Parabolic SAR indicator to form a trend-following system. Entry conditions require price to pull back to key Fibonacci levels (such as 38.2%, 50%, 61.8%) while the Parabolic SAR flips to confirm trend direction, at which point a trade is opened in the trend's direction. Exit conditions rely on Parabolic SAR reversal signals or fixed take-profit and stop-loss levels. Position sizing uses fixed lots without any dynamic adjustment mechanism. Money management lacks risk-proportion control, with no position sizing based on account balance or volatility. The overall strategy logic is clear, but risk management measures are relatively weak, lacking trailing stops and partial exit mechanisms.
Strengths
- Dual confirmation from Fibonacci and SAR reduces false signals and improves entry quality
- Trend-following strategy performs well in clear trending markets with reasonable risk-reward ratio
- Simple and clear strategy logic, easy to understand and optimize parameters
- Parabolic SAR has built-in trailing function that follows trend development well
Weaknesses
- Fixed lot sizing lacks dynamic position management, unable to adjust risk exposure based on market volatility
- Prone to frequent false signals in ranging markets leading to consecutive losses
- Lacks trailing stop mechanism, profitable positions may give back significant profits during pullbacks
- Fibonacci level selection is subjective, different market conditions may require different parameters
Possible improvements
- Add ATR-based dynamic stop-loss and trailing stop to adapt stop distances to market volatility
- Introduce ranging/trending market filter (e.g., ADX) to pause trading or reduce position size in sideways markets
- Implement risk-percentage-based dynamic position sizing instead of fixed lots
Risk assessment
Overall risk: Medium
- Fixed lot sizing without dynamic position control may over-risk small accounts
- Lack of trailing stop may cause significant profit giveback on winning trades
- Frequent SAR flips in ranging markets may cause consecutive losses
