If you are patient and have good reaction, you can try doing scalping. Regarding assets, choosing something too volatile can be dangerous with scalping, but achievable.
But you gotta get used to scalping...

Hmm, I can't give any recommendations to you but personally I would use only scalping strategy on the forex markets opening positions with big lots because thanks to the VPS server, the speed of my order execution will be ultra fast and even take profit and stop losses will execute instantly without any slippages.
