The system is rigged and has been rigged like this
It's rigged against day traders. But you can still get by just fine as a value or growth style investor who is seeking long term ROI. You're just a sucker if you think you can outplay the machines minute-by-minute.
PS: The book “Flash Boys” is a great reading about HFT.
Michael Lewis was the GOAT back then. Shame he parlayed his fame into FTX infamy.
