What Is Anti-Martingale Strategy?

An Anti-Martingale Strategy involves reducing bet size following a loss and increasing it after a win, thereby enhancing risk management.

An Anti-Martingale Strategy is a risk management approach commonly used in betting, trading, and investment activities. This strategy involves adjusting the bet size based on the outcome of the previous bet, promoting a controlled approach to risk.

Historical Context

The concept of betting systems dates back to ancient times when gamblers and investors sought methods to increase their chances of success. The Anti-Martingale Strategy is the inverse of the traditional Martingale Strategy, which originated in 18th-century France.

Types/Categories

• Classic Anti-Martingale: Increases stake size after each win and decreases after each loss.
• Fixed-Fractional Anti-Martingale: Uses a fixed percentage of capital for each bet.
• Progressive Anti-Martingale: Adjusts bet sizes based on a progression rule following a win/loss.

Key Events

• 18th Century: Initial discussions around betting systems begin, eventually leading to the concept of Martingale.
• 20th Century: The Anti-Martingale Strategy emerges as a risk-averse alternative to the Martingale Strategy.

Detailed Explanations

The Anti-Martingale Strategy’s fundamental principle is to “ride the winners” and “cut the losers.” This ensures that risk exposure decreases after losses and increases during winning streaks.

Mathematical Formulas/Models

The Anti-Martingale formula can be expressed as:

$$ \text{Bet Size}_{n+1} = \begin{cases} \text{Bet Size}_{n} \times (1 + \text{Win Rate}) & \text{if win} \\ \text{Bet Size}_{n} \times (1 - \text{Loss Rate}) & \text{if loss} \end{cases} $$

This formula implies scaling up after wins and scaling down after losses.
