The word "position" comes from China, that is, the "Yuan Datou" for daily payment by banks. Ten Yuan Datou piles up to only one inch, so it is called "position". Now the position is a common word in the financial industry, which is often used in finance, securities, stocks and futures trading.

Position, also called "headgear", which means money, is a popular term in financial and business circles. If the bank's income exceeds its expenditure in all the receipts and payments of the day, it is called "multi-position"; If the payment exceeds its income, it is called a "short position". The behavior of predicting the number and number of such positions is called "position rolling". The act of trying to transfer funds everywhere is called "changing positions" If the temporarily unused funds are greater than the required amount, it is called "loose position", and if the required funds are greater than the idle amount, it is called "tight position".

For example, if an investor buys a gold long contract, it is said that the investor holds a gold long; If a gold transaction is short, it is said that investors hold short positions in gold. When investors sell their short gold positions back to the market, it is called liquidation.
