First time using Terminal (Padre) and when I select Exit Strategy and enabled Take Profits how come sometimes the TP line doesn’t show on the charts?

Then when I set my Stop Loss why doesn’t it show on the charts where I can adjust it and know where my Stop Loss is going to be? Putting in percentage but I don’t see it visually? How to change this?

Also if I have a live trade am I able to change the TP and SL if I want to change it?

Terminal seems so confusing cannot work how to do these things I hope someone can clear it up.
