Specification
This Expert Advisor (EA) is an automated 1-minute Gold (XAUUSD) momentum breakout straddler built specifically for MetaTrader 5 on brokers like Exness. It replaces manual pending order placement with an instant-click execution system and built-in trade protection.
Core Functionality & Mechanics
* 1-Click Range Bracketing: When you click the on-chart "⚡ STRADDLE NOW" button, the bot scans the high and low of the previous 3 candles (InpLookbackCandles = 3) and places a Buy Stop above the highest point and a Sell Stop below the lowest point with an added buffer.
* One-Cancels-the-Other (OCO): The moment one side is triggered by momentum, the bot automatically detects the open position and cancels the opposite pending order.
* Auto-Trailing Stop: Once the position moves into profit by a set amount (default: 120 points / 1.2 USD), it moves the Stop-Loss to lock in profit and trails price at a fixed distance (default: 80 points).
* Broker-Specific Safeguards:
* Auto-selects Exness order filling modes (IOC / RETURN) to avoid execution rejection.
* Checks broker StopsLevel and FreezeLevel to ensure orders are not placed too close to the current spread.
* Enforces a maximum spread threshold (default: 60 points) to block entries during volatile, wide-spread news events.
Key Parameter Reference
| Parameter | Default Value | Purpose |
|---|---|---|
| InpLotSize | 0.18 | Position size per trade |
| InpBracketBuffer | 150 points ($1.50) | Distance placed above recent high / below recent low |
| InpStopLoss | 200 points ($2.00) | Hard Stop-Loss from entry |
| InpTakeProfit | 300 points ($3.00) | Fixed Take-Profit target |
| InpMaxSpread | 60 points ($0.60) | Cancels/blocks execution if the spread exceeds this limit |
| InpOrderExpiryMin | 5 minutes | Auto-cancels pending orders if neither side triggers |
To help align this with your overall trading plan:
* What account type (e.g., Exness Raw Spread, Zero, or Standard) and total account balance are you trading with?
* What is your preferred risk tolerance per trade (fixed lot size vs. percentage-based risk)?
