Expert Advisor – Auto-Adjust Lot Size in Trade Panel

MQL5 Experts Forex Trading robot/indicator debugging Statistics and mathematics

Specification

I need an Expert Advisor (EA) for MetaTrader 5 that automatically adjusts the lot size in the volume field at the top-left of the terminal based on a fixed 1% risk of my equity.

Features:

1. Display a movable horizontal line on the chart that I can drag.

2. Calculate the distance from the line to the live price in pips.

3. Retrieve my account equity in real-time.

4. Get the pip value of the symbol dynamically.

5. Use this formula to calculate the correct lot size:


Lot Size = (Equity × 0.01) / (Stop Loss in Pips × Pip Value)


6. Automatically update the “Volume” field at the top-left trade panel (so I don’t need to manually enter the lot size).

7. If the line is below the price, it means I want to place a Buy trade (stop-loss at the line).

8. If the line is above the price, it means I want to place a Sell trade (stop-loss at the line).

9. Display the calculated lot size as a text on the chart for confirmation.


🚨 Important: This EA must automatically set the lot size in the trade panel at the top-left of MetaTrader 5, not just display it on the screen.


Platform: MetaTrader 5 only (not MT4).
