[PX] RSI Barcolor

This script simply colors the candles based on the defined "overbought" and "oversold" RSI-levels set in the input section of the indicator.

If the price is below the oversold level, the candle is colored in yellow.
If the price is above the overbought level, the candle is colored in aqua.
If the price moves back between both levels, no color will be applied.

Might be useful for some of you ;)
