Hello zehua,

Yes, this is possible.

Many users use the Market Analyzer window as a stock screener with an indicator column and row and cell filters.

You can also call data from multiple instruments in a NinjaScript and take actions based on logic using the data.

Use AddDataSeries() for a an indicator or strategy.

Use a BarsRequest from the addon approach for anything else.

Thank you! I have a custom stock list of over 1k stocks. Is there a way to write C# code to program a custom stock screener using market analyzer? If I create an indicator that shows true when the condition is met and false when it is not met, and filter in market analyzer with all these 1k stocks, will that work?

Hello zehua,

Yes, this is what the Market Analyzer is typically used for and would work as long as the brokerage or data provider allows for 1000 simultaneous subscriptions.

Note, 1000 scripts is going to needs a lot of CPU and memory resources.
