Good scalping book?

Guys I would like a recommendation of a good scalping book or book/tactics that people with a lot of free time can read/do. I choose scalping because I have a lot of free time which I want to use wisely. I have read a few books and I trade for more than a year so I don’t need “forex for begginers” books. I just quit my job(not because of forex), and I would like to spend atleast 8 hours on forex(trading, learning) to be a better trader than now. If you don’t have any idea or a recommendation of what to read/do or just don’t have anything nice to say, please avoid replying on this post. For others who do, thank you in advance.

“Forex Price Action Scalping: an in-depth look into the field of professional scalping” by Bob Volman is particularly good.

Thank you very much!
