A bankroll is money set aside specifically for betting. It should be separate from essential expenses and sized so that a losing stretch does not affect day-to-day finances.

Use a consistent unit

Define one unit as a small percentage of the total bankroll and keep ordinary wagers close to that amount. Consistency makes results easier to evaluate and reduces the temptation to chase losses.

• Set the bankroll before the season begins.
• Record the line, price and result of every wager.
• Review decisions over a meaningful sample.

Protect the process

No strategy eliminates variance. The goal is to make repeatable decisions, preserve enough capital to withstand normal losing runs and judge performance honestly over time.
