This script changes the color of the candles based on uptrend (green), downtrend (red), neutral/chop (yellow). It uses an ATR and Pivots to determine the direction, or lack of. Since all markets move differently and market volatility changes, you will need to adjust the settings to find a potential match for the day. It's pretty simple to use. Just enter in the direction of the trend and exit (or reverse) when the candle color changes.
