I have some requirements for automated trading. I am a bit too lazy to learn C++ or Java - would rather spend time on the logic of the algo, than on the hardcore IT codes. My preference is to use something like Matlab for automated trading. There seems to be two alternatives from the net: (a) Exchange Systems, Inc (www.exchangeapi.com) and (b) Matlab Trader (www.matlabtrader.com) Has anyone have had any experience using either of them? My focus is on US equities only at present. I would really appreciate if anyone can throw some light. Thanks.
