# MT4 One-Click Close All Orders Script - Complete MQL4 Source Code

This article provides a fully functional script for MT4 that closes all open positions with a single click. Unlike EAs that run continuously, this script creates a persistent button on your chart that executes batch closing when clicked. It is an essential tool for manual traders who need to exit positions quickly during volatile market conditions.

Tool Features



  • Visual button interface on chart (右上角)

  • One-click batch closing of all orders

  • Supports both BUY and SELL positions

  • Real-time execution feedback via Alert

  • Error handling with detailed logging

  • Button persists until chart change or manual removal

    Script Parameters Explanation



    This script has no input parameters - it works out of the box. All settings are hardcoded for simplicity:

    | Element | Description |
    |---------|-------------|
    | Button Position | Fixed at top-right corner, 130px from right edge |
    | Button Size | 120 × 32 pixels |
    | Button Color | Red (C'192,57,43') for high visibility |
    | Slippage | 3 pips (adjustable in OrderClose function) |
    | Order Filter | Only closes orders matching current chart symbol |

    Installation Instructions



    1. Copy the code: Open MetaEditor in MT4 (press F4)
    2. Create new script: File → New → Script (NOT Expert Advisor)
    3. Paste the code: Replace all default content with the code above
    4. Compile: Press F7 or click Compile button
    5. Check for errors: Ensure 0 errors in the bottom panel
    6. Run the script: Drag from Navigator → Scripts onto any chart
    7. Use the button: Click the red "一键平仓" button to close all positions

    How to Use



    1. Attach the script to any chart (EURUSD, GBPUSD, etc.)
    2. A red button labeled "⚡ 一键平仓" appears at the top-right corner
    3. Click the button whenever you need to close all orders
    4. A confirmation alert shows how many orders were closed
    5. Check the Experts tab for detailed execution log

    Compilation & Modification Tips



    Common compilation issues:
  • Ensure file type is Script (.mq4), not Expert Advisor

  • Verify `#property strict` is present

  • If your broker uses 4-digit quotes, pip calculation remains correct


    • How to customize:
  • Change button position: Modify `OBJPROP_XDISTANCE` and `OBJPROP_YDISTANCE` values

  • Change button color: Adjust the RGB values in `C'192,57,43'`

  • Modify slippage: Change the number `3` in OrderClose function calls

  • Change button text: Edit `OBJPROP_TEXT` string value


    • Reference



    This script source code is independently compiled and tested on MT4 build 1420+. The implementation references standard MQL4 event handling patterns and order management functions as documented in MetaTrader 4 Help.
