Quote from TradeViper:
Hey Y'all. Just thought I would jump in here. Moe I don't know how much you know about the CX platform but if you are trading that kind of size you will undoubtetly have RFQ, RFT and Chat priviledges enabled, this allows you to deal with the prime broker directly so size is not a concern, unless you are using a "predatory" scalping system, then you will get thrown out of any direct trade platform. That is why longer term trading is far more efficient and safer when trading size.
