I am interested in starting to system trade. I have several years of option market making experience in commodities. I also have many years of hobby programming experience (C, VB, VBA, Java, some C++). I am looking to start with a low cost platform to get my feet wet with systems and backtesting. With maybe a little charting as a kicker! So, any suggestions between Ami or NT? are there others that i should be looking at? I am concerned mostly with energy futures and commodities, not equities. Thanks!!
