Three places to check for Open/Close data:
1. Brokerage APIs: If you have a trading account (e.g., Interactive Brokers, Alpaca), check their API documentation. They often provide historical daily bars for options, which include the Open and Close prices, for free to clients.
2. Nasdaq Data Link (Quandl): Look through their available options datasets. Many vendors on their platform sell cleaned EOD options data.
3. CBOE Data: The official exchange often sells inexpensive EOD options data files that contain the daily settlement/close price. (https://datashop.cboe.com/option-eod-summary)
