Strategy Collection

Is there a way to programmatically determine what charts a user has open and also determine what instruments the charts are using? I would also like to determine what strategies, if any, each chart is running.

Hi scottreynolds,

There is no way to access which charts are open, or find out if there are strategies running.

You can access the interval type and value using BarsPeriod. This shows what interval is used only where the script is currently applied.

There is Id for the interval type and Value for the interval value.

For instrument there is this class and available properties:

You can make the strategy post that information to the OutputWindow or an external text file.

As a vendor, I would like to be able to control the number of contracts a user can run for a strategy. The strategy could limit the number but the user simply has to open another chart and run the same strategy to defeat the limitation. Is there a way to handle this?

There are no supported NinjaScript items for solving this. There may be some things you can do in C#, like mutex. See this thread for possible ideas:
