theoretically it is possible, but practically, it’s extremely hard to execute profitably, even with perfect execution, don't expect to be profitable. And that's right, slippage is one of the main killers. 
You got the right idea.

Think of it as like this: 
This isn’t a strategy, it’s Kinda be like a war of latency. Cuz you’re not competing on market logic or whatsoever. You're competing on the execution speed, and that’s where retail loses.
So don't try to outsmart the market. Just why you wanna do that??
