You don't need a book to learn options. Everything you could possibly want to know about options are available online for free.

90 day restriction for what? Pattern day trading?

You can request a one time flag removal if you are unable to meet the equity maintenance call of $25,000 instead of waiting 90 days.

Or switch to a cash account. Read up on good faith violations. Options settle T+1. Stocks settle T+2.

Else, I recommend TD Ameritrade (thinkorswim) and Tastyworks.
