To modify the Stop Loss (SL) or Take Profit (TP) levels of a trade in MT5, follow these steps:
Locate the trade you want to modify in the "Trade" tab of the "Terminal" window at the bottom of the screen.
Right-click on the trade and select "Modify or Delete Order."
The "Order" window will appear, showing the current parameters of the trade.
In the "Stop Loss" or "Take Profit" fields, enter the desired level for the SL or TP.
Once you have set the new SL or TP levels, click on the "Modify" button to save the changes.
You will receive a confirmation message indicating that the modification has been successful.
Note: Modifying the SL/TP levels of a trade does not guarantee execution at those levels. It is important to consider market conditions and potential slippage when setting SL/TP levels.
