Update of open interest

Hi. At what time in the morning the open interest on US equity options is updated? Also, where it is first reported?
Thanks in advance.

 

OCC is sending the Open Interest info to all industry members.
If I remember well, I think it's somewhere around 6 am ET.

 

We get it two hours before the open.

 

I think it’s around 6 am. I am not from the US. I think you should check it with someone who is from there.
