Many manual trading errors stem from calculation mistakes rather than analytical shortcomings. Traders may misjudge lot size, set a wider stop loss than intended, or inadvertently turn a 1% risk trade into a 4% one.Also recommended: Partial Close Multi TP Manager for MetaTrader 5 - similar expert with strong performance on MetaTrader 5.
This panel is designed solely to perform these necessary calculations. Every order is initiated by a user-initiated button press; the panel never opens trades automatically.
Panel Features:
- Displays your risk percentage and its equivalent value in account currency.
- Shows the stop distance, configurable in points or derived from ATR (Average True Range).
- Calculates the precise lot size required to match the specified risk and stop distance.
- Indicates the current spread, open volume, and floating profit/loss.
Trading Buttons:
- BUY / SELL: Executes market orders with predefined stop loss and take profit levels. The take profit level is a configurable multiple of the stop loss distance (defaulting to 2R, or can be disabled).
Important Considerations:
- Lot size is always rounded down to the nearest volume step to prevent exceeding the intended risk limit.
- Orders are subject to broker volume limitations and free margin constraints to ensure successful execution.
- Stop loss levels adhere to SYMBOL_TRADE_STOPS_LEVEL and freeze level requirements, adjusted by the current spread.
- On netting accounts, the panel accounts for potential position offsetting and alerts the user if an opposite order would reduce the position instead of opening a new one, preventing unattached stop losses.
- All trading rules are configurable via inputs, including magic numbers and maximum spread.
Self-Testing Functionality:
Set the InpSelfTest input to true and run the EA in the Strategy Tester. This will rigorously test the lot size calculator and the order entry logic, providing a PASS/FAIL result for each check. The published version has passed all tests, including the critical verification that the actual risk taken precisely matches the requested risk. Tested on MetaTrader 5 (hedging and netting accounts), 2026.
