Most traders are wasting their time trying to predict the market.
Quant firms play a completely different game.
A real quant system is built around four steps:
Find. Prove. Size. Repeat.
First, strip away the noise and isolate the residual.
Then prove the edge survives costs, slippage, and out-of-sample testing.
Size it small enough to survive variance.
Then repeat it thousands of times.
A 51% win rate can be enough.
One trade is noise.
Repetition is what turns the edge into a business.
