Recently, I've seen quite a few discussions about the Martingale strategy, so I want to organize some of my thoughts.

Honestly, the Martingale strategy looks very simple—doubling down. In theory, if you have enough capital, betting on the up or down side can indeed guarantee a 100% win rate, making losses impossible. But the key word here is "in theory."

I’ve realized that the biggest problem with the Martingale isn’t the strategy itself but human nature. For example, if you have a $10k capital and open a $1,000 long position, and then the market keeps falling sharply. You start adding to your position, adding more, and more, until all your capital is invested. At this point, your goal isn’t really about making money anymore; it’s about breaking even. When the price finally rebounds, most people will close most of their positions near breakeven. You think you’re trading, but actually, you’re driven by fear and worry to recover your money, ending up with only tiny profits. Even more terrifying is that when your funds can’t support the position anymore, you’re left watching everything go to zero. That’s why most people using the Martingale strategy end up taking small profits while risking big losses, using large capital to chase small gains, and ultimately blowing up their accounts.

But I’m not saying the Martingale strategy can’t be used. In fact, if used correctly, it can be quite effective. The key is how to use it.

In futures trading, my approach is to combine the Martingale strategy with box theory and volume analysis, with an emphasis on setting stop-losses. Strictly speaking, true Martingale doesn’t use stop-losses—liquidation is the stop-loss. But I usually use Martingale in key price levels to add positions or average down, which is a kind of small-scale Martingale. For example, if Ethereum is oscillating between 2300 and 2800, and it doesn’t break out of this range, I trade within the box. When the price approaches 2700, if I’m unsure whether it will break out or bounce back, I might short at 2765 and go long at 2850. I set a stop-loss above at around 2920. This way, the Martingale strategy combines box theory with stop-losses. The exit is either when the market moves beyond expectations, triggering a stop-loss, or when it hits the target profit, exiting accordingly. That’s the core approach of small-scale futures Martingale.

Spot trading is where the Martingale strategy truly shines. My method is simple: combine Martingale with major mainstream coins with high market value, buy low when prices are low, and sell high when prices are high. The most important thing is to grasp the initial position and the overall trend. The timing for adding to positions is left to the market, while other aspects are left to time. Humble as I am, I can say that this strategy has not resulted in losses so far—only differences in profit size. It’s especially suitable for large capital seeking stable compound growth. Spot trading is essentially straightforward, foolproof trading. The biggest challenge is timing; if you understand the time cycle, you’re on the right track.

Finally, I want to say that all technical analysis is static; the market is alive. Whether it’s the Martingale strategy or others, they all need to be flexibly adapted to current market conditions. Simply copying textbook methods will only lead to market lessons.
