I rather not talk about what I use to trade or how I trade, takes a lot of money and an impressive amount of time to come up with something with an edge, you just don't give stuff like that away.

Absolutely, looks great in a bull or doji year, comes a bear year and it either wipes you out, or you don't perform due to using under-leverage.

A combination of a setup that begins in a fast timeframe and morphs into a slower timeframe, a dream come true.
