From your posts I inferred you were trading on order-book-derived features on a single asian crypto exchange using some sort of LSTM or CNN ensemble, and were looking to try the same thing in US listed instruments. Has that changed? Are you now trading order book dynamics in US futures or equity names? If so what broker or prop firm did you end up with?
This type of LOB feature extraction has been widely publicly known at least since the Penn-Lehman competition in 2005. Definitely easy edges existed then, even for automated retail traders. What makes you so sure those edges haven't been traded down to the risk-adjusted FF rate in the 13 years since?
