MT4:
On the MetaTrader 4 or Metatrader 5 platforms, you can place a pending order via the main 'Order' window.
- Simply change the 'Type' from 'Market Execution' to 'Pending Order'.
-
A drop-down menu will then appear that will allow you to specify whether the pending order you are about to place is a Buy Limit, Sell Limit, Buy Stop or a Sell Stop Order.

MT5:

❗️Important Note: When the market is volatile, pending orders are not guaranteed and they might be executed at a price different than the one you have specified in your order.
