FX profit/loss is always in CHF for any USDCHF trades.
FX profit/loss is always in CAD for any USDCAD trades.
FX profit/loss is always in JPY for any USDJPY trades.
Just keep those currencies in your IB multicurrency account.
This new to me that Patsystems is providing their servers "at no cost".
In general they will charge something like $0.50 per side.
