I need the usage of something like global variables, that are visible for alle ninjascripts in the same charts. is there any solution to achive this?

Custom static objects? (I've tested)
Attached properties? (I haven't tested yet)

Hello ReneRose,

There is not really a concept like that in supported NinjaScript, can you provide specific details on what scenario you are trying to complete? There is likely a better approach or specific way to do the task in NinjaScript already that does not involve global variables.

I would like to switch from another trading app. In that app, I have a small ecosystem of tools for testing trading signals. It is designed like a modular system, allowing individual scripts to communicate with each other. This makes it possible to test various indicators or other constructs as filters for a trading system with very little effort, without needing to rebuild the charts. For example, it is necessary for an indicator activated as a filter to pass on its status for each period. The cumulative statuses are then evaluated by the trading system.

Hello ReneRose,

When using NinjaScript, there's no concept of script communication because there's already a framework in place to use those scripts without adding them to a chart. For example, if you wanted to use the SMA in your C# code, you'd simply call the SMA in the code; it doesn't need to be added to a chart or have any special communication added. The general process for NinjaScript is to create indicators that produce a plot, which is the result of its calculation. In your other scripts, you can then call that indicator to get that calculation.
