Setting SL VS no stting SL

Actually, it's controversially

advantage SL: I don't know price the market will force my position so far, i can to limited my loss

disadvantage SL:  maybe price go back again, and the finally you still profit

THIS DANGEROUS, the next step:
The advantage NO SL: you still hit the profit
The disadvantage NO SL: you can MARGIN CALL

The Methode:
The margin you must look first, especially how much a lot position will effect your margin's
second: you can use average, sell again despite of loss
WARNING:
you can try with small position or demo first

I will share my history to explain that...
