Hi all, I mainly trade quant strategies. Therefore I have systems that are running automatically. Often times I also like to put on a few discretionary trades and to hone my discretionary senses and intuitions. Ideally, if I can simulate these trades and build a virtual portfolio it would be great. Over the long time, I will be able to learn what worked and what failed. Of course I can write my own programs to keep track of these simulated trades as well as the virtual portfolios. However I would like to see if there are ready-made software/platform so that I don't have to reinvent the wheel. I can imagine many companies and people have put lots of efforts into creating such software. So any recommendations? I am talking about software that can do simulated futures/FX trading as realistic as possible. And I have Bloomberg and Reuters as my real-time data-feeds. Thank you!
