The stock market is ever-changing, and if investors without any skills and knowledge enter the market, they will definitely be left with nothing left. As an investment market, there are many kinds of stock market dynamics, and investors' investment methods should also change accordingly. Take the double play in the stock market as an example. What does it mean?

what do you mean by double play?

a double kill in long and short positions refers to a situation in which the trading direction in the market is bullish and bearish, and both of them are in a downward situation at the same time. Among them, multi-party refers to buying a bullish party, and empty party refers to buying a bearish party. Double play usually occurs when the index is consolidating. At this moment, no matter whether investors are long or short, they will not make money.

especially when the market starts to plummet after the day's sharp rise, it is easy to have both long and short kills. In the investment market, the negative impact brought by the lack of time value of the subject matter fluctuation is too large, or the decline of volatility will cause the situation of both long and short losses in the stock market. The common situation is that the fluctuation of the subject matter is insufficient. When the fluctuation of the subject matter is insufficient, the subscription contract is bound to fall.
