Forex - Lot size calculator

Updated
This indicator is specifically designed for Forex traders who need a convenient lot size calculator directly on their charts. It allows users to input their account balance, risk percentage, and stop-loss distance in pips to easily determine the appropriate lot size for a given trade, ensuring effective risk management.

Key Features:
  • Lot Size Calculation: Automatically calculates the lot size based on user-defined inputs: account balance, risk percentage, and stop-loss distance.
  • Error Handling: The indicator only works with Forex pairs. If applied to non-Forex assets, a clear and prominent red error message will appear in the bottom-right corner of the chart, reminding the user that this script is intended exclusively for Forex trading.
  • Simple Visualization: The calculated lot size is displayed in an easy-to-read table directly on the chart.


How to Use:
  1. Add the indicator to a Forex chart.
  2. Enter your account balance, risk percentage, and stop-loss pips in the input fields.
  3. The indicator will display the calculated lot size for the chosen Forex pair.


Important Notes:
  • This script is intended only for Forex assets. If used on other instruments (e.g., stocks, crypto, indices), an error message will be shown.
  • Always validate lot sizes with your broker, as there can be slight variations depending on broker specifications and leverage settings.
