I really don't know which one is better... But if you have both knowledge in one "trader".. you might have a superior especie ! Just see the difference of a trader from the 60's and a trader from the 90's ...and you will see that actually the difference is in the "computing" knowledge and not so much in "only" in the math knowledge! It seems to me that trader in the future will have both knowledge.... 50% traditional trader knowledge + 50% "real" computer science knowledge. Best Regards To All, FDS
