Getting Error on calling EventHandlerBarsUpdate

[liorsham]

Hi,

I'm running live strategies (Calculate=OnPriceChange), NT8.0.0.9,
I'm seeing the trace file is sometimes filled with:

Strategy <myStrategy>'': Error on calling 'EventHandlerBarsUpdate' method: Index was outside the bounds of the array.

I never get those on my backtests.
what is the reason for that?
I don't see any other details in the trace/log files + no exception is being caught by my strategy code.

The error you mention is only caught during real-time updates, and would appear based on the exception to be related to multi-series scripts using OnBarUpdate().

So we can help isolate this error, can you please elaborate a little more on what your strategy is doing? Is it adding additional data through AddDataSeries()? If so, what time frames or instruments are being added, in addition to the primary?

That's correct - I'm calling AddDataSeries 4 times from OnStateChange (State=State.Configure), it's called for x1,..,x4 minutes intervals, some of the data series are equal sometimes (e.g. x2=x3=x4), then I'm doing several calculations on their previous bars (e.g. SMA).
I'm not adding any other instruments.

I get it in playback market replay with added series.
