The issue may be the posters understanding of the word scalp. To most traders, it refers to clipping one to a small handful of ticks on a futures or cents on a stock. Trying to do that on a five minute chart would be like trying to saw wood with a hammer.
Not too long ago I was in a heated debate with someone that stated he scalps via the 1 hour chart.

More strange, he can not figure out why it doesn't work like that and he too stated he's tried many systems...nothing works.
