Don't Forget the Simple Tools

The NYSE TICK (intraday) can tell you a lot...

TICK in green, SPY in white. I used the declining TICK to tell me probabilities, at least as far as the TICK were concerned were for a lower SPY. This is just one chart, but you put the pieces together like a detective and it's a very simple tool with good prediction qualities. For instance the pop above the channel right now should be watched to see if it is only a momentary move or starts a new trend.
