I all I'm moving to Ninja Trader in a bit and start trading ES after trading SPY heavily for the last months. Anyways been using Ninja Trader with Zenfire dome for quite a while and pretty happy with data-feed (no lags but disconnections from time to time). But i'd like to hear from people with experience with Zenfire, is it a good data vendor for the futures market? And how is IQfeed comparing to that. I need a fast reliable data feed the will allow me to scalp a more faster charts. So anyone with experience with one of this data vendors in the futures market, or any other he reccomands is welcome to comment. Thank you all.
