Error "tried to load additional data". when optimizing s strategy

[guillembm]

I am receiving the error message: "'MyOptimizer' tried to load additional data. All data must first be loaded by the hosting NinjaScript in its configure state."

I am sure that all data is in the local PC. Could this affect the optimizer results?

Hello guillembm,

The error means a called hosted indicator is using AddDataSeries() to add a data series. This AddDataSeries() call must also be added to the host strategy.

From the help guide:
"Should your script be the host for other scripts that are creating indicators and series dependent resources in State.DataLoaded, please make sure that the host is doing the same AddDataSeries() calls as those hosted scripts would. For further reference, please also review the 2nd example below and the 'Adding additional Bars Objects to NinjaScript' section in Multi-Time Frame & Instruments"

Thanks for your reply.

In this case this was not the problem. I don't have added series neither in the indicator nor in the strategy.

I solved the problem increasing the upper range of the time series to optimize.
