Anything that is related to HFT or day trading is almost impossible in my experience as well. The big funds can do it but I dont think retail has a chance with these approaches.

Have you researched trend or stage analysis? They're slower strategies and dont offer the get rich quick hype, but they do have far better success when done well.

Yeah, I think all arbitrage setups of any kind are already being exploited by those with a hard to replicate edge (nano second execution/latency, very very deep pockets - typically your large market makers like Citadel). Just think about it: Jim Simons (RIP) had been doing it for longer than most of us have been alive.

Pretty soon AI won’t be optional, it’ll be the only way to run a profitable quant shop.

Btw I think your YT channel would be a good idea.
