In all honesty it's been too long since I've experimented with QC, but I'm really hoping to get back to it more regularly.  A question I have though, looking ahead to turning on actual live trading, is how do folks manage multiple live trading strategies?  

Is it possible to run mutliple QC projects in parallel and live trade? 

Or, can a user only run one QC project in live trading mode and would need to code the project in such a way as to handle multiple strategies in the OnData method?
