"Mathematical modeler who finds edge in data."
To you, the market is just a math problem. Emotions are noise; data is truth.
These are the stats that matter for your trading type. Know them. Respect them.
of strategies that look good in a backtest fail in live trading. Overfitting is the silent killer.
Events (which shouldn't happen in a million years) happen every decade. Your risk model underestimates tail risk.
Correlation. In a crash, all correlations go to 1. Your diversification is an illusion when you need it most.
The amount of intuition allowed in a true quant system. If you intervene, you are the bug.
You see the matrix. Price isn't value—it's a data point. You trust backtests more than news headlines. You believe that with enough data, you can predict the probability of any outcome.
You've probably said one of these. Here's why it's costing you money.
"I can predict the future with enough data."
You can't. You can only identify probabilities. The market is a complex adaptive system, not a physics problem. Past performance is not indicative of future results.
"If the model loses, the market is wrong."
The market is the reality. Your model is the map. If the map doesn't match the terrain, the map is wrong. Always.
"More variables equals a better model."
This is called "overfitting". A model with too many variables describes the past perfectly and predicts the future terribly. Simplicity is robustness.
You never think in "right or wrong," only in expected value. This makes you nearly immune to emotional tilt.
You build models that work perfectly in the past but fail in the future. You struggle when human emotion breaks your algorithm.
You are a scientist in a lab, not a gambler in a casino.
Verify servers are running. Verify data feeds are connected. The machine does the work.
Reading papers, testing a new hypothesis. You aren't watching charts; you're watching code.
Checking the "Expected vs Actual" of your models. Is the slippage within tolerance?
Glamorous? No. Essential? Yes. Garbage in, garbage out. You spend 80% of your time here.
Running the new strategy against 10 years of data. Does it hold up?
Refining the execution logic. Shaving 10ms off latency or saving 1 bps on fees.
Learn from those who came before you. The wins AND the wipeouts.

Beat the blackjack dealers with card counting, then beat the market with statistical arbitrage. The father of quantitative trading.
