Quote from Nana Trader:
Just learn Easylanguage (will be best preparatory language out there) and VB & excel if you are not intraday trader or don't want to place more than few trades a day.
You need to learn C++, C#,..only if you are very trading very actively, but i think individual traders seating at home or prop firms are at disadvantage and not gonna make it unless they switch to higher timeframe
few factors that will kill you:
-spread
-commision
-slippage
-missed trades
-random moves
With higher TF, they are out
