Quote from Janed:
Yes, that's similar to other things I trade there. So how do you convert your position from "HE cme apr" to "HE globex apr" or vice-versa without taking a hit???
you don't need to convert anything.you can enter a trade on either.if you bought on globex you can just enter an order to sell on the cme floor and your position is closed. or the opposite if you like. its the same contract specs exactly just differnt methods of entering trades.
