Changing color of candles on certain conditions

Hello,

I need a script, that changes the color of those candlesticks (body and wicks) in the main window, which comply with certain rules:

Input parameters:

x = ratio longer wick/body
y = ratio longer wick/shorter wick

color1 = color of candle, when rule part 1 is true
color2 = color of candle, when rule part 2 is true

(x and y should allow floating point values)

Rules:

IF  close - open > 0 THEN
IF (open - low) / (close - open) > x AND (open - low) / (high - close) > y
THEN color1

IF close - open < 0 THEN
IF (high - open) / (open - close) > x AND (high - open) / (close - low) > y
THEN color2

(Doji's will not be changed)

Thanks & best regards
Oliver
