1。 Pyramid buying method: buy 100 lots of soybeans at 3 100 yuan, buy 50 lots when the price rises to 3200 yuan, and buy 25 lots when the price rises to 3300 yuan again. That is to say, open positions separately and overweight profitable positions, but the number of overweight positions cannot exceed the number of previous positions. The advantage is that if the first position is profitable, it can expand the results, because the number of additional positions does not exceed the last one, even if the callback does not exceed 50%, it will still be profitable. The loss is because it is the first time to open a position. But only when the market is large can it be realized, and the market is not meaningful and cannot be implemented. 2。 Inverted pyramid buying method, buy 100 lots of soybeans at 3 100, buy 200 lots when the price falls to 3000, and buy 300 lots when it falls to 2900. The advantage is to reduce the cost of opening positions by increasing the purchase volume. If there is a rebound, it can protect the capital or even make a profit. Ask for a lot of money, otherwise once you make a mistake, you will lose a lot. And the initial position should not be too large. This is what is often said in the stock market. On the contrary, there is a prismatic position.
