Summary: This article provides a complete, compilable MQL4 script source code for instantly closing all orders on MT4. It includes options to filter by order type (buy/sell/pending) and magic number, with full parameter explanations.




This tutorial provides a production-ready MT4 script source code that closes all open positions and pending orders with a single click. Manual traders and EA users alike need this utility to manage risk instantly during high volatility or before news events.

Why a One-Click Close Script?


MT4's default interface requires multiple clicks to close each order. This script reduces that to one drag-and-drop action, closing all or selected orders in milliseconds. It's an essential free EA download for every trader's toolkit.

How to Compile and Use


1. Save the code as `CloseAllOrders_V1.mq4` in the `Scripts` folder of your MT4 data directory.
2. Open MetaEditor, compile (F7), and ensure no errors.
3. Drag the script from the Navigator panel onto any chart.
4. A confirmation dialog (if enabled) will show the number of orders to close.

Parameter Explanation


  • CloseMarketBuys/CloseMarketSells: Close existing market buy/sell positions.

  • ClosePendingBuys/ClosePendingSells: Close Buy Limit, Buy Stop, Sell Limit, Sell Stop pending orders.

  • MagicFilter: Only close orders with a specific EA magic number. Use -1 for all orders.

  • ShowConfirmDialog: Prevents accidental execution with a popup confirmation.


    • Usage Tips


  • This MT4 script source code works instantly and does not need to remain on the chart.

  • For partial closing, adjust the boolean inputs to filter specific order types.

  • Combine with a hotkey manager for one-key emergency closing.
