The script operates purely for informational purposes; it does not open, modify, or close trades. It retrieves and displays detailed symbol specifications directly on the chart and within the Experts log in a structured report.
The report provides comprehensive details including:
- Current bid, ask, and spread in points
- Symbol digits, point size, and trade tick size
- Tick value, profit tick value, and loss tick value
- Contract size and account currencies
- Minimum, maximum, and step volume
- Directional volume limit
- Stop level and freeze level
- Symbol trade mode and execution mode
- Supported filling modes and order features
- Terminal, account, and Expert Advisor trading permissions
- Estimated margin for a configurable test volume
- Estimated account currency profit for a configurable price movement
The script normalizes the test volume according to the broker’s specified minimum volume, maximum volume, and volume step. Margin and profit estimations are calculated using the native OrderCalcMargin and OrderCalcProfit functions, avoiding reliance on fixed pip value assumptions.
