Article 22 of the Measures for the Administration of Futures Investor Protection Fund stipulates that before using the protection fund, the China Securities Regulatory Commission and the protection fund management institution shall supervise the futures company to verify the loss of investors' margin rights and interests, actively clean up the assets and realize the disposal, and should first make up the margin gap with its own funds and realized assets. Only when it is not enough to make up or when the situation is critical can we decide to use the security fund.
