Clarification on timing of OnBar events

Hi Panagiotis,

i am not 100% sure if this question was answered before as I didn't find a completely matching answer...

If a cBot is running on a M1 chart and processing of an OnBar event takes longer then one minute (let's say 5 minutes) - what happens with the bars opened in the meantime?

• Are those events added to a queue and triggered later (i. e. delayed)?
• Or is every OnBar event a separate thread?
• Or are those bars just skipped and the next bar opened after the process was finished triggers the next OnBar event?
• Or is it handled in a different way?

Many thanks and best regards,
Christian
