For such a complicated question, I won’t be rewarded with many points. It would take a long time for others to answer one by one.

I am speculating in futures now, let me tell you:

Long exchange: long positions change hands, which means that old positions are sold to close positions, and new positions are bought to open positions. .

Short exchange: Short exchange of hands, which means that the old short position is bought to close and the new short position is opened by selling.

Double opening: long positions are opened to buy and short positions are opened to sell. At this time, the total position increases.

Short opening, short position opening on the initiative.

Short closing, short positions are actively closed. Double draw, the old bulls and the old shorts close their positions. Long positions are closed, long positions are closed actively.

Double leveling: Long selling positions are closed and short buying positions are closed. At this time, the total position is reduced.

Multi-open: Multi-open is a detailed term of double-open, which means that the current transaction price is at the (lowest) selling price (long buyers actively buy), which is called "multi-open" .

Short opening, short position opening on the initiative. The purchase price is the transaction price and the increase in position is a positive value.

Short closing, short positions are actively closed. The selling price is the transaction price and the increase in position is a negative value.

Bulls are closed, longs take the initiative to close their positions. Taking the buying price as the transaction price and increasing the position as a negative value

This is probably the case.
