This indicator is mostly known because of Market Cipher. The script that was published under the name Wolfpack Id is for some reason closed source, but as it turns out there is of course no secret sauce involved, the original indicator goes way back and the thing that was then called Wolfpack Indicator is simply a Signal Line with 3,8 settings. I added a simple divergence hunter for some extra Informations that might help, brought it up to contemporary pinescript standards, added Alerts and made the whole script open source, as it should be and as the original script also once was. Have fun!
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.
