i worked in a prop firm before trading synthetic oil futures (cal spreads, butterfly/condors). i remember in my previous company no one program trade and tested strategies. only base on observation because all we have been focusing is some synthetic spread with slow move. usually need to hold on several weeks/days. can anyone tell me is there any ways to trade synthetic spreads with program trade? just like a interface for us to code and test and then go live trading. i am finding the cheap way to trade. i used to use CQG but they don't have programming interface. thanks!
