just outta curiousity are u tradin' again or u on the lookout for a good fx broker and havent yet open an acct...and what about index futs...u plannin' to touch 'em again?...sgx is fun to trade, and very predictable, since u already pretty familiar with the index why dont u give it another try.
As I understand it you see only quotes from your banks your prime broker has counterparty relationships with. So if your prime broker was small you might see a wide spread and if it was CITI or DBK you would see a tight spread.
