It's not gambling if you have a grasp on the market, know how the market moves, know when your'e wrong, work trades in when you're right. That's trading.
But if you just think markets are random, there is no systematic language defined behind the psychology of each and every move, with all market participants including retail, funds, the fed, as well as external events that may affect mood, well, then you're gambling.
Market's no good until the gap from 7/31 fills.
