Many Fibonacci EMAs are calculated and then tracked using custom-colored candlesticks so that your chart remains very clean. This setup is mainly used for scalping on the 2min. Feniks uses gray candlesticks and then all of the custom-colored candlesticks to know when to react to price action. WARNING: Do your own due diligence and try it out. Also, the script's default colors were determined with the chart's candlesticks being gray for both bullish/bearish candles. You'll probably have to change some of the colors to make use of the script if your chart's candlesticks are not similarly configured.
