Closing a position is to wash away the list in your hand relative to opening a position. Specifically, it means buying when opening a position, closing a position means selling, opening a position means selling, and closing a position means buying. Closing a position is also locking a position, which is the profit and loss of your order. The specific operation is to open a warehouse with the same month as the original single variety and the opposite direction of buying and selling. A short position means that after the margin is removed, the loss is greater than the available funds in the account. After the company is forced to draw a tie, the remaining funds are the total funds MINUS your losses, and generally there will be a part left.
