How to sign a bill when trading with foreign exchange MT4 software?

Just select the currency pair you want to trade in MT4 "Quote" and right-click "New Order" (or use the shortcut key F9). In the new window that opens, find the "Transaction Type" drop-down menu, and then click the "Pending Transactions" option. Select "Type" in the "pending transaction" area below, set the price in the input box, and click "Place an Order". After that, all pending orders will be found at the bottom of the trading window (that is, the current position window).
