Faster than what ?
You do need some type of ai if you want an automated trading system that can backtest correlation ideas on such huge volume datasets that are visually orientated.
And you need next gen ai IF you want ai itself to carry out re-enforcement learning and testing on the visual type data bookmap has. Because its a lot of data for which you have to tell it to play a breakout type hedging game. And current generation Ai hallucinates and doesnt have proper self monitoring before it outputs decisions. You can used older ai of course but it will not be a straightforward process.
And obviously you dont need ai, if you just want to do manual trading. Or implement simple ideas
