I am using the Open API to get historical tick data (ProtoOAGetTickDataReq).

In reconciling the Bid and Ask prices, what is the process (outside of a actual match on symbol and timestamp), in resolving the other price data.

Hi there,

Bid and ask prices are independent from each other. Sometimes are updated together but most of the times they are updated separately.

Best regards,

Thank you for the prompt response and clarification. So in an effort to facilitate back testing with the historical tick data in Open Api, similar to the OnTick event in cautomate, is it safe to say the cbot OnTick event simply raises the OnTick event with an SymbolTickEventArgs obj as soon as it has both an Ask and Bid price?

No, OnTick is raised whenever any of the two prices is updated.

Ah! I see. Now that makes a lot of sense. Thanks again
