A one-day chart pattern where prices sharply reverse during a trend. In an uptrend, prices open to new highs and then close below the previous day's closing price. In a downtrend, prices open lower and then close higher. The wider the price range on the key reversal day and the heavier the volume, the greater the odds that a reversal is taking place.

nice indicator.. what is the best chart timeframe for this one? Daily? what about 10min?
Could you explain how the 'Inputs" n length' works?

I loaded this up yesterday works well on a 2min chart for me

@carneyse71 I believe this was designed for the daily timeframe but you can use it on any timeframe as long as you what how to use it. The length is the lookback period.
