Does anyone know where I can get historical bid/ask charts for options? I found OptCharts but they only offer charts for options whose underlying stock is part of the Dow Jones.
i'm you can do this with IB. chart or get the data from them via API and build\chart whatever https://www.interactivebrokers.com/en/home.php
Do they chart bid ask or just last prices? I find that last price data tends to have a lot of slippage. I'll check it out though. Thanks
you can chart whatever the hell you want don't know if they have it on demo,but you can try it anyway. go on their webside->login-> u:edemo p:demouser
