I am currently with Mirus/Zenfire (using NinjaTrader). I have an automated strategy and would like to lower commissions and lower latency. I am thinking leasing a seat on CME (how much $$ ?) will lower commissions and co-locating (how much $$ ?) will lower latency. Can somebody point me in the right direction for both/either? Any brokers/FCMs for one stop shop? Thanks in advance.
