Yep. Same for me, if it works on the 15-min it must work on the daily or on the 20-tick chart. To me it's not even a method, it's just how the markets work. But it never ceases to fascinate me. The risk:reward ratio helps too. Not to greedy: but not too cheap either.
The ratios never change regardless of volatility, but you probably already see that given you are operating in such a slow environment.
It really makes conversations about future direction silly...I don't know what the market will do tomorrow but I know how to take advantage of it.
