In general, what is a martingale, that so many traders mistake it for a “lifesaver”? In fact, it’s just a strategy of increasing your bets after losses—starting out from casinos, and then applied to financial trading.

The core is very simple: you trade, lose, and then increase the size of the next order. Lose again, increase again. Keep going until you win and cover all the previous losses. The idea is that when you win, you don’t just get your money back—you also make a profit.

So how does martingale work in real life? It’s used to average down when an asset’s price drops. For example, you buy a coin with $10, the price falls to $0.95, and you open a new order with $12 (increase 20%). The price falls again to $0.90, and you open another order for $14.4. Each time, the average buy price becomes lower, and even a small rebound can put you in profit.

But here’s the part I want to warn you about: martingale looks a lot like a casino strategy for good reason. In a casino, players place $1 on black, lose, $2 lose, $4 lose, $8 win—getting back all the losses plus $1 profit. Trading is similar, but the market isn’t roulette!

What’s the upside? Quickly recovering losses, no need to predict reversal points—gradually “following” the price. But the downside is much bigger: the risk of losing your entire capital if you don’t have enough money for the next order, severe psychological pressure, and most importantly—there are markets that keep falling without recovering; at that point, martingale turns into a disaster.

I’ll calculate it for you specifically: with $100 capital, an initial order of $10, increasing by 20% each time—after 5 orders your total spent amount is $74.42. If the price keeps falling, your money won’t be enough for the next order.

How to use martingale correctly? First, set a small increase rate—10-20% is reasonable. Second, calculate in advance how many orders you can average down with. Third, don’t put all your money in right away—keep some as reserve. Fourth, use additional filters—if the market is in a strong downtrend, avoid averaging down. And most importantly: remember, this is a high-risk strategy that requires serious calculation and discipline.

Calculation formula: Next order = Previous order × (1 + martingale ratio / 100). For example, with 20%, starting at $10: Order 1 = $10, Order 2 = $12, Order 3 = $14.4, Order 4 = $17.28, Order 5 = $20.74. Total = $74.42.

In summary, martingale is a powerful tool but it’s dangerous. Beginners should use an increase rate of 10-20%, and always have a plan for prolonged market drops. Trade smartly, manage risk, and don’t let emotions take over—that’s how to survive long-term in the market.
