Put: Selling and Opening-Buying and Closing (Ping Jin)
A novice must spend the night in a light warehouse.
Short selling is called selling and opening positions. Choosing to sell and open a position on the trading software, and then determining the price and the number of lots, that is, ordering short, is not complicated and clear at a glance. Futures can be sold short. If not, you can sell it first. Think of it as the exchange lending it to you first, and then you can make a buying transaction and return it to the exchange.
If you have money, you might as well invest in stocks. Most of these futures are your own investment experience accumulated from the stock market for many years. You must only see the leverage and high returns of futures from the perspective of problems, but you don't realize that once the direction is reversed and the position is not closed in time, the losses will multiply in a short time. I don't think anyone can afford a 500,000 guarantee fund, which is only enough to make a few contracts, but you can learn a lot by investing in stocks.
I suggest that you have nothing to do to see the trend of the great wisdom stock index futures market. There are many operations to learn from.
Generally speaking, it is to open a position first, whether it is bullish or bearish, and sometimes it is possible to change positions in the middle, from more to more, and then close the position and buy more, that is, short selling and short selling. Basically, this idea is that novices basically don't take overnight positions. As the delivery date approaches, the positions will drop significantly and basically be converted into contracts for next month.
Supplement:
Basically, the mature futures price trend is unbreakable and basically the same, so it will naturally answer questions. When you judge that there is a possibility of a decline in the market outlook, then open a short position. If the target 300 hormones rise at this time, in order to avoid losses, it will become more, so that your short contracts will be replaced by long contracts.
