Summary: The Martingale Strategy states that when a trader experiences a loss, they should immediately double the size of the next bet. By repeatedly doubling the bet when they lose, the trader will theoretically even out with a winning trade at some point.

The Martingale Strategy is a strategy of investing or betting introduced by French mathematician Paul Pierre Levy. It is considered a risky method of investing. It is based on the theory of increasing the amount allocated for investments, even if its value is falling, in expectation of a future increase.
