What is anti-martingale strategy in trading?

Anti-martingale is the opposite of martingale: traders increase position sizes after wins and reduce them after losses. This approach compounds profits during winning streaks while protecting capital during drawdowns. For example, a trader may double size after each win but return to base size after a loss. Anti-martingale aligns with probability theory, making it safer than martingale. However, it requires discipline and careful calibration to avoid overexposure. It is popular in trend-following systems where streaks are more likely.
