I use TTAdv of IIFL and odin of RKG...they can be used simultaneously ..no problem at all..
Plus, having used ODIN, he had to unlearn some habits and learn new ones which was hard during trading hours. Even though I suspect Indiabulls might co-exist with ODIN, I am weary of undergoing same predicament of "learning" new tricks; or worse, constantly switching between that and ODIN that I am so used to. I know my answer in my heart - which is to use another pc with ODIN - cough, cough!
