OPEN-SOURCE SCRIPT
Updated Higher High Lower Low Strategy (With Source Code)

This script finds pivot highs and pivot lows then calculates higher highs & lower lows. And also it calculates support/resistance by using HH-HL-LL-LH points.
Generally HH and HL shows up-trend, LL and LH shows down-trend.
If price breaks resistance levels it means the trend is up or if price breaks support level it means the trend is down, so the script changes bar color blue or black. if there is up-trend then bar color is blue, or if down-trend then bar color is black. also as you can see support and resistance levels change dynamically.
If you use smaller numbers for left/right bars then it will be more sensitive.
