I wanted to get the pulse of this community about something I've been considering. For those of you who trade two very different styles -- in my case, short-term algo-driven trading, and mid-term (3-6 weeks) news-driven trades -- do you use multiple accounts? Or are you running everything through the same account? I'm considering opening a second (linked) account on IB to simplify performance testing, but haven't looked closely enough at the policies yet to see if there are potential downsides.
