Hi guys, I'm looking to trade a vertical spread in IB but I can't find the OI and volume for the legs. I've included a snapshot of what it looks like. It seems that volume/OI is only visible for individual puts in the Calls and Puts section. Can you please help? Thanks
Calls and puts are you legs, so what’s wrong with seeing the volume and OI on those Calls and Puts in the options chain? And there is no such thing as OI for spreads. A spread is just an informal combination of two options. You can also combine options in many other ways that are only in your imagination and no one else may be trading. Though you can see what are various option combos being traded during the day in the spread book (won’t work after hours): https://www.interactivebrokers.com/...uidebook/mosaic/complexorderstradescanner.htm
Just to add a bit to what guru has said... When you execute a spread trade, you may be buying one leg from a guy in Singapore and selling the other leg to a guy in Boise, Idaho. It may be a spread for you, but it could be something very different for the parties taking the other side of each contract. There is no OI or volume for spreads. BMK
