(((H-L)>3*(O-C))AND((C-L)/(.001+H-L)>O.6)AND((O-L)/(.001+H-L)>O.6))

This is a pcf for candlestick hammer, I use this in a scan and have gotten no result in 6 months.  Is this  the pcf I should be using in my scan?

I want stocks with a Bullish Candlestick hammer pattern.

I am not a candlestick guy (at all), but my best guess as to the intent of this formula would be:

H - L > 3 * (O - C) AND C - L > .6 * (H - L) AND O - L > .6 * (H - L)

It should return true when the candle as a whole is more than three times the size of the body and the body is entirely contained within the top 40% of the candle as a whole.
