Principle of Operation
1. Data Retrieval:
The indicator gathers real-time data on the trading instrument, including:
- Minimum and maximum lot sizes
- Tick value
- Spread
- Number of digits
- Account data (balance, currency)
2. Connection Check:
If there is no connection to the broker, a message is displayed on the chart, and no further calculations are performed.
3. Optimal Lot Size Calculation:
- Risk Determination: The indicator considers the specified risk value (e.g., 2% of the account balance) and the stop-loss value.
- Calculation of Risk Amount: It computes the amount of money the trader is willing to risk.
- Lot Size Determination: The risk amount is divided by the product of the stop-loss and the tick value. The result is adjusted to the nearest allowed step and constrained within the minimum and maximum lot sizes.
4. Displaying Information on the Chart:
- If enabled, the spread value is displayed.
- For each specified stop-loss, the calculated lot size is shown.
- Additional risk information may be displayed in percentage terms and the account's currency.
