Just to add
Seen so many punters who demand leverage of 400:1 use it and abuse it.
If some one is offering you 400:1 they want you to blow up your account by dangling the carrot.
Trade very small positions at first and allow that extra leverage to work for you and not the broker.
DO NOT put in a stop loss in the market. Instead replace it with a paper stop loss and see how you travel.
You will be surprised that you have the correct position/idea only for it to be taken away by a possibly a large market order and then it retraces back favourably to your trade.
For the retail punter the object of the game is to keep yourself in it .
