Any way to interact with other charts?

[ErikY]

I know this is probably really complicated, but has anyone come up with a way to interact with multiple charts within NinjaScript?

I can imagine creating some type of web services with some type of state service that each chart can ping the services with some data on bar change so that other charts can call that server, but wondering if anyone has every tried or done anything like this? This would largely be for working with multiple timeframes without having to bog down higher timeframes with smaller candles

Hello ErikY, thanks for posting.

There is nothing supported that will make multiple charts communicate with each other. This thread will remain open for other members of the forum to provide input.

Kind regards.

Hello ErikY,

you can exchange data between two "charts" using a public static array.

Example:

Strategy 1 (Chart 1) "SendData"
Init: public static bool [] SendArray = new bool [10000];
OnBarUpdate(): SendArray[CurrentBar] = yourBoolToSendToReceiveData;

======
Strategy 2 (Chart2) "ReceiveData"
Init: private bool [] ReceiveArray;
DataLoaded: ReceiveArray = new bool [10000];
OnBarUpdate(): ReceiveArray[0] = SendData.SendArray[CurrentBar];

You can transfer 10000 historical data if you first open the SendData strategy and then (!) the ReceiveData strategy.
The number of data in the SendData and ReceiveData strategies must be identical for the historical data.
For realtime data a public static variable is sufficient.

Kind regards
