1. Open the MT4 software, and you can see the open orders in the Terminal window at the bottom of the software.

2. Double-click the number corresponding to "stop loss" or "profit" in the order (usually 0.0000).

3. The "Modify Order" window pops up to set the stop-loss and profit-taking price.

4. There are two ways to set the stop-loss price and take-profit price: The first way is to directly enter the price difference from the current price, and then click Copy to automatically calculate the stop-loss price and take-profit price. Second, enter the price directly in the "stop price" and "profit price".

5. Finally, click the Modify button.

6. After the stop loss is set successfully, the set stop loss price will appear in the "Stop Loss" column of the order (as shown in the figure). When the price reaches the stop-loss price, the order will automatically close the position and leave.
