Grid EA & Optimization Performance

Specification

Code a grid expert advisor (EA) MQL5 that uses a sort of hedged laddering mechanism.

Core Logic Outline:

1. Initial Setup:
• Open a double trade (Buy & Sell) at the current market price.
• Set two pending double trades (Buy/Sell limits) at a fixed distance on either side (e.g., ±X pips).
2. On Trigger Event:
• When price hits one of the pending double trade levels, execute the new double position.
• Immediately:
1. Close the profitable leg of the previous active double trade.
2. Place a new double pending trade above the newly triggered trade.
3. Replace the closed profitable trade (to restore the double trade structure).
3. Loop:

• Continue this cycle as the price moves, creating a self-adjusting grid that always maintains symmetry.

4. In Summary

• Each time a double trade pending orders line is triggered,
• Close the profitable leg of the last double trade
• Replace the close profitable trade with a pending order at its initial level
• Create a new pending double grid order above it at the distance set in the input
