What metrics matter most in bet tracking?

Key metrics include ROI (return on investment), win rate, average edge, total profit/loss, and CLV (closing line value). ROI and total P&L tell you if you're profitable. Win rate alone is misleading without considering odds.

Why you should track every bet

Measure your edge. Without a betting log, you're guessing whether you're profitable. Tracking reveals your actual ROI across different markets, platforms, and strategies.

Eliminate bias. Bettors tend to remember wins and forget losses. A tracker gives you the unbiased truth about your performance, helping you make data-driven adjustments.

Optimize your strategy. By categorizing bets by platform and market type, you can identify where your edge is strongest and allocate your bankroll accordingly.

ROI

Profit divided by total amount staked. Anything above 0% means you're profitable over your sample.

Win Rate

Percentage of settled bets won. Meaningful only in context of odds — 30% at high odds can beat 70% at low odds.

Total P&L

Your bottom line. The only number that truly matters — the sum of all wins and losses.

Frequently asked questions

Everything you need to know about tracking your bets.

Why should I track my bets?

Tracking bets lets you measure your actual ROI, identify which markets and strategies are profitable, and avoid common cognitive biases like selective memory. Without data, you're flying blind.

Is my data stored securely?

All data is stored locally in your browser using localStorage. Nothing is sent to any server. Your bet history stays entirely on your device and persists between sessions. You can export it as CSV at any time.

What metrics matter most?

ROI (return on investment) and total P&L are the most important. Win rate is useful context but misleading on its own — a 30% win rate at high odds can be more profitable than 70% at low odds. Track everything and let the numbers tell the story.
