TradingHours null when autoconnecting at startup

[saltminer]

Hi,
a client has received this error when autoconnecting to data at Ninja startup. Why would the TradingHours be null? (The strategy is not referencing any TradingHours object in OnStateChange().

Hello saltminer,

Thank you for the post.

It would be difficult to say from these details what may be happening, however, I do have some questions surrounding the script and how it was run.

Is the script adding any secondary series?

Is a standard set of trading hours being used when applying the strategy, or is a custom defined set of hours being used?

Does the strategy use the "Use Instrument Settings" or has a specific session been selected?

Does this happen if you close the workspaces that are opening at startup and remove all instances of the script, then apply 1 instance in a new workspace using the scripts default settings?

These would all be helpful to know and test to better understand the scope of the problem. I assume based on the details that you have tried with success when not using auto connect, is this correct?



Another item I can note is the message at the bottom:

Failed to process 'EventuallyConnected': 'One or more errors occurred.'

This message can come from how NinjaTrader deals with daylight saving time that occurs at midnight however I am unsure if this additionally happens for other reasons. We have seen this with Brazil as it happens to start DST at midnight while all other known DST begins at a different hour. The current suggestion for timezones which reach this message is to change the PC time to UTC-5 (eastern US) or UTC-6 (central US) until a fix is implemented (NTEIGHT-13334).

I am unsure if this message is related to the null message, so that would also be something that can be tested to check if it is. I would like to have these details if that were to be the case so I can further this report.



I look forward to being of further assistance.
