I've been trading 2-3 instruments manuallyusing 5 -30 min bars for a couple of years using a low cost broker. It this point I want to expand the instruments I trade to 20-30 and I would like to fully automate my trading. I'm new to full trading automatization, so I was wondering what software you would recommend to trade 10-20 (could be more) instruments at a time using 5-30 min bars, that calculate position sizes based on real time risk parameters, also has the option of using OCO order type? Any comments are appreciated. Thank you.
