The main reasons why gold cannot be completely extracted are as follows.

1. When there is a position in the futures account, all funds cannot be transferred out. This is determined by the margin system of futures and the debt-free settlement system at that time. In the case of holding positions, available funds = (available funds-mark-to-market profit) *( 1- position margin/customer's equity)

2. The part of the profits liquidated on that day cannot be paid. Futures investors shall not pay any money before the liquidation of profits on that day. The purpose of this regulation is to strengthen the protection of investors' rights and interests and prevent the risk events of transferring investors' funds by knocking.

3. Reserve funds in futures accounts. Due to the calculation accuracy and other problems, the available funds calculated in real time during the transaction period may be slightly different from the results calculated at the time of settlement. If "reserve fund" is not set, investors will make full withdrawal according to the real-time calculation results of trading time, and the account may be slightly out of position due to excessive withdrawal after settlement.

4. The withdrawal amount exceeds the single withdrawal limit of the futures company. Futures companies generally have restrictions on the amount of single withdrawal by customers.

5. Not at the time of deposit and withdrawal.
