@the5kyliner its very simple . Once you open a trade for example $6500 is your entry point and now you decided to long bitcoin and invested 1 bitcoin with 10 x leverage .
So now if bitcoin price increased by $100 and went to $6600 then or later you can decide if you want to close your trade now or not . If yes, then you made $100 x 10 = $1000 profit on that trade .

I hope this made it clear to you :)
