Today I want to share a trading strategy that many people often confuse — martingale. This name sounds complicated, but the idea is actually very simple: when you lose, you increase your bet, keep increasing until you win to recover all previous losses.

Initially, martingale was used in casinos, especially in roulette. Players bet on a color, if they lose, they double the bet, if they lose again, they double again, until they win. When they win, they not only recover all losses but also make a profit. Then traders saw the cleverness of this strategy and started applying it to financial markets.

How does martingale work in trading? When the price of an asset drops unexpectedly, instead of cutting losses, you open a new position with a larger amount. For example, buy a coin with $10 at a price of $1. The price drops to $0.95, you open a $12 position (a 20% increase). It drops further to $0.90, you open an additional $14.4 position. In this way, your average purchase price decreases. As soon as the price recovers a little, all positions will be profitable.

But this is where the danger lies. If you don’t have enough money for the next position, all previous losses will remain. I’ve seen traders start with $100, applying a 20% martingale, and after 5 trades, they have spent $74.42. If the market continues to decline, they won’t have enough money for the 6th position. The psychological pressure is also huge — constantly increasing bets can be very stressful.

Calculating martingale is not too complicated. The formula is: Next position size = Previous position size × (1 + Martingale rate / 100). For example, with a 20% martingale and an initial $10 trade: trade 1 is $10, trade 2 is $12, trade 3 is $14.4, trade 4 is $17.28, trade 5 is $20.74. Totaling $74.42.

To use martingale reasonably, set a small increase rate — around 10-20% is best. This helps keep the volume increase moderate. Before starting, calculate how many trades you can open with your deposit. Always reserve some funds for additional trades. Most importantly, do not apply martingale during a strong downtrend — at that time, averaging down can lead to disaster.

In conclusion, martingale is a powerful tool but also very risky. It only works when you have proper risk management, discipline, and good psychological control. Beginners should start with the minimum increase rate and always have a plan for prolonged market declines. Trade smartly, manage risks, and don’t let emotions dictate your decisions.
