I don't see the option to add the "open interest" column in the option trader, seems kind of odd since it is a very important indicator. Any way to get it?
Yeah, it's a massive pain in the ass to have to use my other brokerage account to get this info. I'd love to have the open interest for the options. One of the things I monitor is suspicious options activity that signifies insider trading, and I try to play along with it (Had I known about DJ's 3000+ call blocks, I would've went along for 10 contracts just on speculation that someone knows what they're doing).
