This is a TradingView indicator which will display the key levels for the prior 5 trading days for HOD and LOD, as well as the Gamma key levels for Gamma Flip Point, CALL wall, and PUT wall.

The python script will fetch the latest Gamma levels which are then updated into the indicator. Copy and paste over the prior levels. Too modify which symbols to pull, edit the symbols list at the top of the script.

Place files in home directory in a ~/Gamma/ directory, and run from a cron job or fire off manually each day to update the latest Gamma levels. Then edit your indicator and paste in the new levels. Save, and your levels should automatically update in your charts.
