<h2> AI Adaptive Signal Trader</h2>
<p><strong> AI Adaptive Signal Trader</strong> is a fully automated Expert Advisor that combines three independent technical signals with an online, self-adjusting weighting mechanism inspired by adaptive machine-learning (multiplicative-weights / "Hedge" style) algorithms. After every closed trade, the EA rewards the signals that agreed with a winning trade and penalizes the signals that agreed with a losing trade, gradually shifting its own internal weights toward whichever signal has been more reliable in current market conditions.</p>
<h3> How It Trades</h3>
<p> Three independent signal modules each vote -1 (bearish), 0 (neutral), or +1 (bullish):</p>
<ul>
<li><strong> Trend signal</strong> - EMA(fast) vs EMA(slow) crossover state</li>
<li><strong> Momentum signal</strong> - RSI position relative to configurable bullish/bearish levels</li>
<li><strong> Breakout signal</strong> - Price position relative to Bollinger Bands</li>
</ul>
<p> The three votes are combined into a single weighted composite score. A trade is opened only when the composite score crosses a configurable threshold in either direction. Every position uses ATR-based Stop Loss and Take Profit, and an optional ATR-based trailing stop with built-in minimum-distance and take-profit-proximity safety checks.</p>
<h3> Adaptive Weight Learning</h3>
<p> When a position closes, the EA looks back at which of the three signals agreed with the trade direction and updates each signal's internal weight using a multiplicative update rule: weights of signals that agreed with a winning trade are increased, weights of signals that agreed with a losing trade are decreased. Weights are clamped to a configurable range and renormalized after every update, then saved persistently (per symbol and magic number) so learning carries over between terminal restarts.</p>
<p><em> Note: this is an on-chart adaptive weighting mechanism built entirely with native MQL5 logic. It does not connect to any external server or third-party AI service.</em></p>

</ul>
<h3> Input Parameters</h3>
<ul>
<li><strong> Magic Number</strong> - unique identifier for this EA's trades</li>
<li><strong> Time Frame</strong> - timeframe used for signal calculation</li>
<li><strong> Max Spread (points)</strong> - maximum allowed spread to open a trade</li>
<li><strong> EMA Fast / EMA Slow Period</strong> - trend signal moving averages</li>
<li><strong> RSI Period, RSI Bull/Bear Level</strong> - momentum signal settings</li>
<li><strong> Bollinger Bands Period / Deviation</strong> - breakout signal settings</li>
<li><strong> Learning Rate</strong> - speed of weight adaptation</li>
<li><strong> Min/Max Weight</strong> - clamping range for adaptive weights</li>
<li><strong> Vote Threshold</strong> - composite score required to open a trade</li>
<li><strong> ATR Period, Stop Loss (ATR), Take Profit (ATR)</strong> - risk management</li>
<li><strong> Lot Size</strong> - fixed trade volume</li>
<li><strong> Use Trailing, Trail Start (ATR), Trail Step (ATR)</strong> - trailing stop settings</li>
</ul>
<h3> Recommendations</h3>
<p> Test the EA on a demo account first to confirm it fits your broker's trading conditions and your risk tolerance. Use the Strategy Tester with real tick data to observe how the adaptive weights evolve over time before trading live. As with any automated trading system, past behavior does not guarantee future results - always use appropriate risk management and position sizing for your account.</p>
