EA Bill Williams Alligator

ALLIGATOR STRATEGY

Fully Automated Expert Advisor for Gold Trading | MQL5 / MetaTrader 5 | Version 5.10 | XAUUSD / GOLD Only

1. Backtesting Results — Real Ticks

VERIFIED: Real tick data (99% quality) | 2021–2026 | 4+ Years

The equity curve grows steadily and smoothly throughout the entire 4-year period — including 2021–2023 when gold was in a correction phase. Maximum drawdown remains below 10%, which is exceptionally low for this level of return.

IMPORTANT!

For both backtesting and live trading, please use only the attached set files from the Comments section — available for 2-digit and 3-digit brokers. If you are not sure how many digits your broker uses, simply run the EA in the MT5 Strategy Tester with both set files — you will quickly see which one fits your broker.

The EA was built without a visual interface to keep it lightweight and fast. If you would like to visualize it on your chart, download our companion indicator from the Comments section — completely free — and attach it to the same chart where the EA is running.

Please use moderate risk settings in your trading. Let us not forget that backtests are based on historical data, and the future remains unknown for all of us. Even though the EA uses a modern Money Management strategy, avoid trading with excessive lot sizes.

2. What Is This Expert Advisor

EA Bill Williams Alligator Strategy is a fully automated trading system developed exclusively for trading Gold (XAUUSD / GOLD) on MetaTrader 5. The system identifies moments when the gold market is in a clear trend and only enters a position when multiple independent conditions are satisfied simultaneously. This significantly reduces false signals during choppy or sideways markets.

Supported instruments: XAUUSD (standard naming used by most brokers) and GOLD (used by RoboForex, Exness, FXPro and others).

Important: This EA is developed and optimized for Gold ONLY. Using it on other instruments is not recommended.

3. Strategy Overview

The system is based on the classical Bill Williams theory for identifying market trends through dynamically shifted moving averages. It recognizes three phases of the market:

• Sleeping market — EA does not enter positions, waits for the market to activate
• Awakening market — the system prepares and monitors entry conditions
• Active market (trend) — enters in the direction of the trend with clear levels

The key advantage is its multi-layer filtration system. The EA requires several independent conditions to be satisfied simultaneously before opening any position — dramatically reducing false signals and improving trade quality.

Risk Management

• Dynamic SL/TP — adapted to current market volatility (ATR-based)
• Trailing Stop — automatically moves SL to lock in profits
• Daily Loss Limit — stops the EA when the daily loss limit is reached
• Trend Filter — blocks positions during a global bear market

7. Running a Backtest

• Symbol: XAUUSD or GOLD | Timeframe: M15

8. Important Notes & Risk Disclaimer

WARNING: Past performance does not guarantee future results. Trading financial instruments carries a significant risk of loss.

• The backtest was conducted with lot size 0.15 on a $1,000 account — this is an aggressive setting
• Recommended: use lot 0.01 per $1,000 of capital for conservative trading
• Only trade with funds you can afford to lose
• Always test on a demo account before going live
• The EA performs best during strong gold trends
• Monitor your account at least once per day
