Good bankroll management is the difference between recreational fun and going broke. Most experts recommend betting 1-3% of your bankroll per bet (your "unit"), and limiting daily losses to 5-15% of bankroll. This ensures you can survive inevitable losing streaks while capitalizing on winning ones.
Set a daily stop-loss and stick to it. When you hit your limit, walk away. Tomorrow is another day.
Exotic bets have higher variance. Allocate a specific portion for exotics so a bad Pick 4 doesn't destroy your entire day.
If your bankroll doubles, adjust units up. If it gets cut in half, adjust down. Never bet the same amount regardless of bankroll size.
Most bankroll management systems recommend betting 1-3% of your bankroll per bet. For a $1,000 bankroll, that's $10-30 per bet. Conservative bettors stay at 1%, while more aggressive players might go to 3%.
A "unit" is a standard bet size based on your bankroll. If your unit is 1% of a $1,000 bankroll, one unit = $10. This lets you scale bets based on confidence: 1 unit for normal plays, 2-3 units for strong opinions.
Kelly Criterion calculates optimal bet size based on your edge and odds. Since most bettors don't have a true edge, fractional Kelly (25-50% of calculated Kelly) is recommended to reduce variance while still optimizing growth.
Yes. Exotic bets (exacta, trifecta, Pick 4) have higher variance. Many pros allocate a smaller portion of bankroll to exotics (perhaps $50-100/day) while keeping straight bets at standard unit sizes.
