1. Buy at the old bottom or top. When the goods fall to the old top or bottom, there is always a stop-loss order to protect the buying point. When a commodity falls back to the old top for the first time, the second time and the third time, it is always safe to buy. When it falls to the same price for the fourth time, buying is quite dangerous because it almost always falls lower.
2. Commodity prices have broken through a series of tops in the past few weeks. Buy when a small trend or a big trend is reversed on a single commodity chart.
3. The commodity price has crossed the top of the previous week, and it has risen above the most Big bounce in the process of falling back from the top, so buy it when it falls back.
4. Buy when it rebounds from the bottom of the daily limit for the first time and exceeds Big bounce in the last big bear market.
5. Buy when the time exceeds the last rebound before reaching the lower limit.
6. If you buy when the commodity breaks through the breakthrough point, the market will be in a skyrocketing movement at this moment, and the short-term profit will be rich.
7. Buy when the goods fall to 50% of the highest selling price, or 50% between the extremely high price and the extremely low price.
8. Buy for double bottom or triple bottom, or buy at the first, second or third higher bottom, and buy the second batch when the second or third higher bottom forms and breaks through the previous top. Use a stop loss order to protect it from market reversal. You can't always be right. If the stop loss order is wrong, it can help you get out and find ways to make a lot of money. This is the way to lead the market.
9. In the final stage of the bull market, the decline was very small. When it falls back the next day, buy at the lowest price every day and set a stop loss. When the market fell below the lowest price of the previous day, it left.
