You may want to contact the developer of the indicator and ask them about accessing the output from their indicator programatically. Usually, and perhaps you might not have looked at this, but the indicator that you bought, if it was adequately coded, the values should be accessible to you via ninjaScript, Alerts, and and the data box.
To confirm if you can get access to the output, open up a chart, right click, and click on data box. All the indicators and their values should show in the data box. If the values from your indicator isn’t showing in the data box, then the indicator hasn’t been built in a way whereby users can programmatically access the indicator values, and perhaps you can ask the indicator developer to update the software.
Additionally, you could take a picture of the indicator, provide all the documentation of the indicator to Gemini, and ask it to replicate the indicator, so that you have a similar indicator, where about you have access to the code because you wrote it with the help of Gemini artificial intelligence. When you’re using Gemini, if you decide to go down that path, you’ll want to use version 2.5 pro
