TradingView Pine Script Alerts improvement with new data plotted in webhook text field

Hi,

I am currently using TradingView webhook alerts to send signals outside TradingView. As soon as my indicator finds appropriate conditions, it sends the following message:

[Open/Close] [Buy/Sell] [Symbol] [Timeframe]

All these commands above are setup manually.

What I want to achieve with this project is to add the following dynamic values to my alerts in TradingView:

{RSI} {Choppiness Index} {Volume}

Specs:

- Data needs to be extracted from appropriate symbol and timeframe. If chart is USDZAR M15, then alert should have RSI, choppiness index and volume from USDZAR M15 chart

- RSI Length and Source should be customisable for each chart and symbol combination

- Choppiness index length and offset should be customisable for each chart and timeframe

- Volume data should be passed as numbers only

- All these new data fields will need to have only two decimals to avoid lengthy alert messages.

Deliverables:

- Pine script

- Commands to add in alert messages

I look forward to starting the project.
