Algo Trading Required: For the drag-and-drop features and trade execution to work, you must enable the "Algo Trading" button in your MT5 toolbar.

Account Compatibility: This tool works with both Netting and Hedging accounts. It automatically detects your account currency (e.g., trading EURUSD on a JPY account) and handles all conversion math instantly.
