In the stock market, there is generally no need to close positions.

There are essential differences between closing, clearing and shorting stock index futures.

Stock index futures can make profits in both directions. When you open a position, you can go long or short.

Simple explanation: make more money in the stock market and make money by shorting the stock market.

Closing a position is relative to opening a position. In the stock market: buy = open, sell = close, close. Selling the stock index futures you bought is the end point.
