Communication and synchronization between two indicators

[doron]

Hi

I design a chart which will contain two indicators: IndA and IndB.

IndA is complex indicator which computes per bar variables A1 and A2 (it does much more but it is irrelevant here ).
IndB should be another indicator which calculate a value B1 per bar. B1 is computed based on the corresponding values A1 and A2 and some internal logic (i.e. A1, A2, B1 relates to the same bar). Indicator B plot on the chart the value B1 per bar.
I assume InbB will activate somehow a method of IndA with input parameter BarNumber and output parameters A1 and A2 .
However, the given BarNumber might not exist yet in IndA.
Can you help me how to build the communication and synchronization between the two indicators?

Hello doron,

Thank you for your patience.

When calling another indicator from within an indicator or strategy it should result in the needed data loading for that indicator. You should not need to do anything other than call the indicator to ensure the data is available.

In general, you use a plot and call that from the other indicator or strategy. However, if these are not plots (A1 and A2 in your example) and are just variables (such as doubles) you would need to ensure they are updated. We have a reference sample demonstrating calling values that are not plots and also showing how to update values that do not belong to a series. You can find this sample at the following link: http://ninjatrader.com/support/forum...ead.php?t=4991

Please let me know if you have any questions.

Hello doron,

We will update the thread.

You can change the IsExitOnCloseStrategy to IsExitOnSessionCloseStrategy and ExitOnCloseSeconds to ExitOnSessionCloseSeconds.
