Quote from Batman28:
I do not trade.
R is for analytics. why would anyone want to analyse data when u can in R/S. can handle huge data and are fast. execution is a different process. it's probably best to link one above with something else. c++ is over-kill. it's like learning chinese to communicate. has no real advantage compared to others at optimal set up. it's waste of life to learn just to execute. only good thing - alot of support on market. and that's because OUTSIDE of the trading community it actually is useful. I personally like delphi best.
i am not so sure about the "huge" data. and my experience is that for actual trading a number of complex systems, there is no such thing as language overkill.
