I keep the TRIN up at all times -either the 2 minute or the 3 minute chart. The individual bars are less significant than the TRIN trend. It is always opposite of ES. When I see the TRIN rise outside the trend line, I know there will be a reversal or retracement of the current trend. When TRIN is above 1.5 or below .5, the probability for a strong reversal is that much stronger, but just as stochastics can "pop" i.e. a strong trend can overcome an "over-bought" condition of >80%, or vice versa on the "over-sold" side, the $TRIN can do the same.
I also don't stop trading in the middle range.
This works well for the daytrade on the ES.
Peace.
