One Candle Reversal

The script will change the bar color if the bar has a body larger the 55% of the range and a range more then 90% of the 20 period ATR.
OCR bars can be used for risk management (stop loss) or buy/sell decisions.
NB an OCR candle does not guarantee, with any probability, a reversal of direction.
It merely can be in indication of a cleanup action of buyers or sellers.
