    Installation Instructions



    1. Copy the code into MetaEditor (F4 in MT4)
    2. Click File > New > Script
    3. Delete default code and paste the complete code above
    4. Click Compile (F7) - verify no errors
    5. In MT4 Navigator, find the script under "Scripts" folder
    6. Drag the script onto any chart
    7. Adjust input parameters in the popup window
    8. Click OK to execute

    Usage Examples



    Example 1: Close all orders on all symbols with confirmation
  • Set CloseAllSymbols = true

  • Set ShowConfirmation = true

  • Drag script to any chart


    • Example 2: Close only sell orders on current chart
  • Set CloseAllSymbols = false

  • Set CloseBuys = false

  • Set CloseSells = true


    • Example 3: Close only orders from specific EA (magic number 12345)
  • Set FilterMagic = 12345

  • Set FilterComment = "" (empty)


    • Compilation Notes



  • Requires MT4 build 600 or higher

  • The script uses standard OrderClose function

  • For ECN brokers, increase Slippage parameter to 50-100

  • Script executes immediately and does not remain on chart


    • Safety Tips



    Always test the script on a demo account first. The confirmation dialog provides an extra safety layer. Consider using FilterMagic to avoid closing orders from other EAs.
