Can i lose all funds when position is closed? when it hits 25%
Unfortunately yes. 4x leverage means if your securities go down 25%, you loose everything. Make sure you keep adding funds to not hit the margin call on CFDs.
thanks. can you tell me how to calculate how much money will i get if i hit 100%
You mean hit 100% in minus? It will never let you hit that! Are we talking about CFDs or Invest/ISA?
cfd account 100% plus - max profit
You’ll make all the profit! Whatever the leverage was. The return you see, is what you get. You cannot loose more than you invested, but you can theoretically make unlimited money.
