The most important thing in stock trading is the opening, this is a direct quote from Xu Xiang's diary. He condensed the key to opening into five golden rules. If you strictly follow them, you will have a sudden realization that trading stocks can be done this way, especially for friends who only have tens of thousands or hundreds of thousands. As long as you practice these five phrases for a year, I can't say you'll make a fortune daily, but at least you can minimize your losses.

The first sentence, if it opens down 3% and doesn't turn red immediately, run. If the stock drops over 3% as soon as it opens, and within ten minutes it hasn't even touched the red, don't hesitate. It’s like stepping out and encountering a heavy rain; if you don't hurry to seek shelter, you'll just get soaked to the bone. In this situation, it's highly likely that the main players are running away; holding on will only lead to deeper losses. Timely loss-cutting is the wise move.

In the second sentence, after a 20-minute flat period, it rises, so boldly increase your position. If the stock opens flat without dropping and suddenly surges within 20 minutes, it indicates that the main force is testing the waters, like seeing a potentially strong horse just lifting its head and quickly following up. Such stocks often have major movements afterward, and increasing your position at this time is equivalent to insuring your profits; when the opportunity arises, it must be seized.

The third sentence, open 2% to 5% higher without hitting the limit, sell half first. If the stock opens within this range and doesn't surge to the limit within half an hour, it indicates that the main force is dragging its feet. Sell half of the position first to secure profits. Keep the remaining position for observation, allowing for both offensive and defensive strategies, keeping control in your own hands.

In the fourth statement, if it opens more than 5% and does not hit the limit for an hour, sell everything directly. If it opens more than 5% and cannot maintain the limit for a whole hour, this is clearly the main force pushing up to sell off. Don't be fooled by the surface rise. Hurry up and sell everything and leave; if you hesitate for a second, you might become the main force's buyer, getting yourself trapped.

The fifth point: don't rush to sell when the stock opens at the limit up, the trading volume is key. When a stock opens and hits the limit up, don't get too excited yet, keep a close eye on the trading volume. If the volume increases, it indicates that the big players are still buying up shares, so hold on, as it might continue to rise; if the volume is too low, be cautious, as the big players might run away at any moment, taking profits is the safer option.
