Need indicator that combines plots from 3 symbols

[ProfitPilgrim]

How can I make, or where can I get an indicator that combines plots from multiple symbols, at least 3. I've been using _UltimateExpression but it has problems refreshing its plots. I'd also like the indicator to be both NT7 and NT8 compatible.

Hello,

Thank you for the questions.

Using multiple plots and also multiple instruments would be possible in the platform. We have good working examples of both of these items, the first would be the Bollinger indicator.

This indicator shows how to use multiple plots and is a very simple indicator so there are few lines of code in the way.

The best example for using multiple series would likely be the SampleMultiInstrument strategy, this shows how to Add additional series and use them as well.

After reviewing these items, please let me know any questions you have about any of the syntax or topics.

Regarding NT7 <-> NT8 compatibility, there will be changes between the two so at this point I would recommend just code as you normally would for NT7. Once there is a public release of NT8 there will be code breaking changes posted so that you can convert the script.

I look forward to being of further assistance.
