InteractiveBrokers API: an instrument's market state?

I try to find a way to receive the current market state and changes to the market state of a tradeable instrument through IB's API.

For example, I try to get a notification when TSLA moves from market-closed to pre-opening auction and then to the regular trading session, likewise during the day.

The only bit I found so far is https://interactivebrokers.github.io/tws-api/tick_types.html#halted - which gives me a "market halted" indication. That's not what I look for, markets can also go into an auction state throughout a trading session.

I can't find any reference to market states in IB's API. Any solution anyone?

Thanks a lot

Indeed, it seems there is nothing to check if a market is open/closed.

I'm currently relying on getting the book (bid/ask).

A closed market will have:

  1. Bid/ask readings to be 0 (one or both of them).
  2. Bid will equal ask (more common).

By validating the book, you can get a grasp of what is being traded out there.
Obviously, it is not bulletproof, as a market can have a circuit breaker on.

Also note that requesting historical data is not enough, as a market can be open for trading, but without any trades traded so far (zero volume).
