Colored EMA

This is a modified version of the exponential moving average indicator to change color based on trend (red/bearish if price has closed below EMA, green/bullish if price has closed above EMA).

Versionsinformation:

Made color change only after previous candle closed above/below EMA instead of current candle (looks better).
