Every time there is a liquidation, I have my experiences. In the face of the market, even if you stop-loss, you will still face liquidation. The excitement triggered by stop-loss makes you stubborn and continue to trade. If you keep stop-lossing back and forth, your principal will already be lost before you face liquidation. Only by establishing your own trading system can you gain profits from it. Profits are not about size; stop-loss is about rolling profits. Use the profits you earn to trade; this is the most fundamental way to protect your capital. In the absence of market movement, you can trade small positions back and forth to gain some points. Twenty points once, ten times is one hundred points; making a mistake once is okay; just limit the loss to ten percent of the profit!
