You can tell from all those densely packed entries and exits...

Quant trading is stupid. It just mechanically executes a fixed strategy. But the one thing it does intelligently is that it has no emotions at all. It won’t panic during a crash or place reckless orders during a rally...

What lets quant trading beat people has never been judgment, but absolutely ruthless trading discipline.

Take a simple example: breakout trades. If you enter manually and watch the market yourself, can you keep an eye on breakouts across the whole market? No... Even if you spot one, you can’t enter every breakout. Some will win, some will lose, and after a string of losses you’ll start questioning the strategy. But the whole point of breakout trading is to trust that every breakout is real, lock in your stop-loss and maximum daily drawdown, and let the risk-reward ratio do the heavy lifting.

Would you say it doesn’t work? Wall Street still uses this strategy today.

Would you say it does work? Not a single retail trader uses it.
