I don't trade forex much but recently put on a few trades and I noticed that the amount of positive carry that I was making on positive interest rate pairs seemed far less than the amount of negative interest I was losing when I had on negative interest rate pairs. After some digging, I discovered, sure enough, the dealing desk caps the amount of positive interest one can earn, but leaves uncapped the amount of negative interest one can lose.
I'll spare you my rant and simply ask those of you who trade forex who you use and whether they have more equitable interest rate policies?
