Original script is thanks to synapticex I have just migrated to version 3, heavily modified it and added Zones.
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 a publication is governed by House Rules. You can favorite it to use it on a chart.
Thanks again, great script and saved me some time!
