To buy the stock of Shanghai Market Risk Warning Board (ST, *ST), you need to sign a risk disclosure. If the investor does not sign, the system will pop up a prompt asking for signing the risk disclosure.

No signing time is required, and successful signing takes effect in real time.

Risk tolerance is C4 growth and tradable stocks above the risk warning board.

If the above conditions are not met, only the risk warning stocks already held can be sold.

Shenzhen ST and *ST stocks do not need to sign a risk disclosure book, and can be operated directly.
