I'm new to forex, usually trade futures, and I've been on the fence over using IB vs. Gain. I noticed that the rollover rates and interest paid on USD cash balances was quite a bit better at Gain. For example, on EURUSD last week, Gain relative to IB, had paid +175 bps ann. Sure, that's only about $5 per lot but that can add up over time. Also, Gain is paying 2.5% on USD cash balances. If I understood IB correctly, they're paying 0% for $ amts under $250k or so. I know there are a lot of IB fans here on ET. Is IB that much better that traders don't mind a higher carrying cost? FWIW, IB is no deal on futures commissions either.
