A hosted indicator tried to load additional data. ( FYI )

[NickyD]

"A hosted indicator tried to load additional data. All data must first be loaded by the hosting NinjaScript in its configure state."

I used to get this message back in my indicator building days and I just came across this possible explanation in the NT8 Guide. If you are receiving this message, this might be why:

Note: To maximize data loading performance, any NinjaScript object (indicator or strategy as host) which references a multi-series indicator which calls AddDataSeries must include it's own calls to AddDataSeries(). For example, if the code above was included in an indicator, and that indicator was referenced in a NinjaScript strategy, then the hosting strategy will need to include the same calls to AddDataSeries(). When the strategy adds the additional Bars objects, the calls to AddDataSeries() within the indicator will be ignored. If the Bars objects are not added by the strategy in such cases, and error will be thrown in the Log tab of the Control Center that would read - "A hosted indicator tried to load additional data. All data must first be loaded by the hosting NinjaScript in its configure state."

Hello NickyD,

This error is caused if any hosted scripts (such as an indicator that is called from another script), adds additional series with AddDataSeries() but the host script that calls it does not add the same additional series.

The error means that you will also need to add that exact same series to the host script (or calling strategy or indicator).

I have this error since rolling the contracts in the Add() array from 03-20 to 06-20 by simply typing in the new contract code in the Add() series. Never came across this error before. Strategy worked with the 03-20 label - but changing to the 06-20 label causes this error. Need rapid response please. Regards

Hello elliot5,

Did you make sure the AddDataSeries() calls match in both scripts?

Does the indicator run by itself without error on a chart?
