Red and Black bars are selling zone, while green and blue bars are buying zones.
Black and Blue bars are better entry points than their counterparts (red and green ones), and can be highlighted using background coloring of the script.
This is extremely useful in detecting selling zones in a downtrend or buying zones in an uptrend.
Performs best in 2h candles, but can be used on any candle length.
Here is the fun part: Use this script on a 1 minute candle for intraday trades and have fun, profiting!!!
