When you sell an open contract, you can have two kinds of people to deal with you.

1: people who buy first hand (do more admission)

2. the person who bought it even (the person who left short, that is, you continued to do it with his empty order, called changing hands)

Buy, open, enter = buy = do more.

Corresponding appearance:

Sell = sell = short.

Sell open position = sell = short.

Corresponding appearance:

Buy and close positions = buy = go long.

In other words, you are shorting, and you have to do more people to trade with you.

==========================

Inner disk can be understood as the number of hands actively shorting.

The outer disk can be understood as the number of hands that actively do more.

When you look at the disk, you can determine who is better in a certain period of time according to the ratio of the inner disk to the outer disk.

==========================

A little depressed. The options are confusing, hehe.

You don't have to worry about who made the deal with you, whether it's against you, whether you received someone else's list. Pay attention to your point of view.

The daily settlement system of futures is more troublesome. If you hold a position overnight, you don't have to pay too much attention to the result of daily settlement, just use the opening price and the flat price to calculate the profit and loss. Unless you have a heavy position.
