Ah , Thanks for the explanationI have not traded using bonus, however a friend of mine once got a 100% deposit bonus on $200. He was thinking that its fine even if he loses $200 as he was seeing a total of $400 in his account, but when he actually $200 dollars he was not able to use the remaining amount as it was locked basically because bonus is just an extra margin that helps you to enter bigger trades.
. I totally get your point now.
