Hello,

I'm doing some simulations and I can't see any daily options data before 2011. Am I doing something wrong, or there are no options data before 2011?

Thank you,
Ondrej

Good morning,

That is correct, around that time we switched to the OSI symbol standard. Prior to that, symbols were reused and old data was deleted.

Is the historical option data for trades or bid/ask?

Ok, figured it was trades only but thought I'd check. Thanks Tim.
