I have ben with amp for 13 years and they never let me down... so i when i tell you the best futures broker is amp.... please believe me
despite your percieved notion of them being a small broker ... out of every big broker i worked for ... they were the quckest to liquidate your losing positions. They have a max 80 percent loss too which is crazy
Broker's fees, even if they are cheap, are meaningless, it's how our broker executes our trades that counts.
And in the world of futures, where there are no dark pools, no PFOF, no nothing, we can nestle into the fact that all executions on the futures side are clean and crisp. I would think for THAT side of trading there is no variance between brokers. All you gotta worry about are the commish. FOP? That I do not know.
