u need to ask your broker
thanks for the advice !
hope they know something about it
they don't know jack..
There are few brokers that manage the swaps differently.
For example they don't calculate it in floating swap column for open positions but put it directly in balance +/- overnight. With that kind of brokers (two of the major are there) the function marketinfo with argument swap return "0".
Actually i don't know if there is a solution for this issue, i stuck with them sometimes ago for the same reason.
A possible way is to import information about swap directly from their websites but of course is not simple as call a mt4 function.
