    Parameter Explanation



    | Parameter | Description |
    |-----------|-------------|
    | CloseAll | True = close all orders regardless of symbol/magic |
    | FilterMagic | Specific EA magic number to close (0 = all) |
    | FilterSymbol | Currency pair to filter (empty = current chart symbol) |
    | ShowConfirmation | Show confirmation dialog before execution |

    Installation & Usage



    1. Copy code to MetaEditor (F4 in MT4)
    2. Click Compile (F7) - ensure no errors
    3. Drag script from Navigator to any chart
    4. Adjust parameters in popup window
    5. Confirm dialog to execute

    Practical Use Cases



    Scenario 1 - Emergency Close: Market moves against you - drag script to chart, click Yes - all positions closed instantly.

    Scenario 2 - Close Specific EA: Set FilterMagic to your EA's magic number, close only that EA's trades while leaving manual trades open.

    Scenario 3 - Close One Pair: Set FilterSymbol to "EURUSD" to close only EURUSD positions.

    Compilation Notes



  • Scripts run once and terminate, unlike EAs

  • No `OnTick()` or `OnInit()` required

  • Use `#property show_inputs` to display parameter dialog

  • Always iterate orders backwards when closing (i--)


    • Important Tips



    Test on demo account first. This script closes market orders only (pending orders not included). For pending orders, use `OrderDelete()` function. The script calculates profit including swap and commission.

    Reference



    Independent compilation. Standard order closing logic based on MQL4 OrderSend and OrderClose functions.
