Use it as a visual indicator to determine when to enter a trade:
Red = Chop zone (no trade)
Bright red = Tight chop (dear god stay away)
Green = Overbought or oversold (signals permitted)
Bright green = Crossing up/down (take the trade)
To apply the filter, simply add 'and not chop' after your conditions as seen in the commented out example.
