GRaB Candles by mattlacoco with Murrey Math Midline

(use V1.1 now See links below)

GRaB candles and a murrey math "midline" in one script.
Some traders using methods of Rob Booker (40% club, trifecta5) like to use both GRaB candles and Murrey Math to combine, or to compare entry and exit moments.
Color of candles are as GRaB candles.
Midline use: Crossing the midline is a change of color in murrey. Candles closing above the midline would be green and below would be red as murrey candles.
