This is my script for H&Ls. I am still working on it.
EDIT: be careful when using it! It does NOT compare previous H&L levels with those in the making. It can only be used if you hold your positions a long time.
In true TradingView spirit, the author of this script has published it open-source, so traders can understand and verify it. Cheers to the author! You may use it for free, but reuse of this code in publications is governed by House rules. You can favorite it to use it on a chart.
The information and publications are not meant to be, and do not constitute, financial, investment, trading, or other types of advice or recommendations supplied or endorsed by TradingView. Read more in the Terms of Use.
