cvds,
It's hard to say what exactly to look for, cause it's usual stuff and not just something one. Divergences, extreme reading, hooks etc...
Actually main benefit of an indicator in my view is that it smoothes and shows PA in slightly different view thus providing additional clues, what is especially useful on very short and noisy timeframes such as 1min...
Today I understood yoohoo's words that early entry on the shortest TF is really the safest, cause it gives you some extra pips run and a possibility to make a profit in circumstances which are very hard to trade on higher TFs cause they lag and get you in the trade too late...
Hope the attached chart helps.
