Book depth

Is there a specific reason we have ES book depth twice that of all the other instruments? I believe ES is 20 on bid and 20 on offer. It would be super helpful to have a deeper book for other items as well. I’m considering getting Jigsaw to use with a Tradovate’s data, though it wouldn’t be as helpful if I didn’t have a deeper orders showing on the book.

I agree. 20 levels isn’t enough. prices charts are only half the picture.
