A basic question:
What do you do with the balances in other currencies that you end up with. For example I traded USD.CAD and EUR.JPY and now I have a whole lot of CAD and Yen balances which in itself is FX risk which I would prefer to be without. When I traded, I used the same quantity for both sides of the transaction hence the residual in CAD and JPY. My base is USD. It will be a pain to adjust quantity when you close a trade as the nuetral quantity will depend on the traded price. I'm sure that's not the way to go. I trade at IB. I know I can get out of these balances by trading them for USD and pay another bid-offer spread. But thought I'd ask what others do about it.
Thanks.
