Empty bills are used in the foreign exchange, stock and futures markets, and the futures market is the place for futures trading and the sum of futures trading. In the spot and futures markets, there are two concepts: long refers to buying at low prices and selling at high prices, and short refers to buying at high prices and selling at low prices. The contracts held by bulls are multiple orders, and the contracts held by bears are empty orders. The futures market also has long hedging and short hedging.

Extended data:

Bear trap simply means that the mainstream funds in the market are strongly short, inducing investors to panic and sell stocks through the obvious weakness of the disk.

Usually, the index or stock price falls from a high level to a new low level, and the trading volume is very high, resulting in the illusion of a downward breakthrough, which makes panic selling rush out and quickly rebound to the original intensive trading area, and suddenly breaks through the original pressure line upward, making the low sellers empty.

From the technical analysis, bear trap's K-line portfolio often shows a series of long yinxian plunge, which runs through various strong support levels, sometimes even accompanied by a downward gap, triggering a chain reaction of market panic; From the morphological point of view, the bear market trap often deliberately leads to a breakthrough in technical form, which makes investors mistakenly think that there is huge room for decline in the market outlook, and they throw out their stocks one after another, so that the main force can undertake a large number of cheap stocks at a low level. This time is often a good opportunity for investors to get involved in such stocks. In terms of technical indicators, bear trap will lead to a serious deviation of technical indicators, and it is not a deviation of one or two indicators, but often a synchronous deviation of multiple indicators and multiple cycles. Therefore, investors should first identify the bear market trap from a technical point of view, and then implement stock selection from a fundamental point of view.

For example, due to the high international oil price, the international chemical industry is on the rise, and the petrochemical industry in China is still on the rise. If the stock of this industry plummets and technically meets the conditions for the establishment of a "bear market trap", it will become the object of our stock selection. At present, there are many booming industries like petrochemical, which are more likely to be "killed by mistake" by the market in the bear market. Investors can apply the principle of bear trap to draw inferences.

It is worth noting that due to the long-term decline of the stock market, a heavy lock will be formed in the market, and the popularity will gradually decline. But it is often at the moment when the market sentiment is extremely depressed, which just shows that the stock market is not far from the real bottom. Therefore, learning to use the "bear trap" to choose stocks requires not only rational observation, but also greater confidence and courage.
