SPY/SPX gamma exposure data (GEX)

Does anyone know of any websites comparable to for example optioncharts.io that offer real time data for SPX that has gamma exposure data?

Optioncharts only seem to have delayed data.
Barchart doesn't seem to have real time data for SPX either.

 

You're looking for dealer-gamma?

 

I get them from the brokers directly.

That data normally comes from a real-time subscription.

TastyTrade or IBKR have those greeks available on a subscription.

Other brokers must have them as well.

 

What is gamma exposure data? Isn't it zero

 

Unusualwhales.com, apparently - not that I know anything about it.

 

This one looked promising but it looks like it doesn't offer the option to create a GEX chart for more than 1 expiration date at a time.

The information is basically worthless. Check to see what (x)vendor was implying on Dec serial opex.

 

a company called options depth is doing some interesting things if you're into the greeks and positioning https://x.com/OptionsDepth
