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 Edited by ovolansky on May 19, 2018 at 04:42 PM |

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. Tim |

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

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