Can someone please explain either of these two things... 1. If I trade in the spot FX market and I go long on the GBP/JPY it pays me around $22 a day on the Swap or interest difference for 100k USD. I am looking at trading FX via the futures markets and as a large income stream comes from my carry trades I would like to understand how this works on Globex. I know that it is "priced in" but is there a way to calculate what the daily interest would be... Exactly? I just want to be sure that the swap earned in the futures markets is close to what I'm making now on my carry trades in the Spot markets. 2. Can anyone explain Rollover (contract rollover not daily swap) in the futures markets? Is there a way to rollover a contract without taking profit/taking a loss? I manage most positions I have back to profitability and like to hold them long term in some situations so this is important. Thanks for anyone that can provide information... All I've been able to find out is general info "The swap is priced in" or "yes you can rollover positions" and would like to know how you futures traders (That trade currency) handle or figure the Swap rates and how you rollover your contracts without taking profit or a loss. Thanks!
