The Kelly Criterion is a formula that calculates the optimal percentage of your bankroll to wager based on your edge. Most smart bettors use “Half Kelly” or “Quarter Kelly” to reduce risk while still growing their bankroll.
Adjust your unit size every time your bankroll changes by 10–20%. This keeps your risk consistent as your bankroll grows or shrinks.
Divide your daily or weekly bankroll into smaller sessions (e.g., 20–25% per session) to avoid tilt and emotional betting.
Use a spreadsheet or dedicated apps (Bet Tracker, Action Network, or OddsJam Tracker). Record every bet: date, sport, units wagered, odds, result, and net profit/loss. Review monthly to find and fix leaks.
Set deposit limits, loss limits, and time limits on every sportsbook. Take regular breaks. If betting stops being fun, stop immediately.
