China's securities watchdog on Friday issued a draft regulation on the requirements for investors to trade stock index futures.

Investors are required to have a minimum of 500,000 yuan to trade in index futures and must have experience in simulated index futures trading or commodity futures trading, according to the draft published by the China Securities Regulatory Commission (CSRC), which is open to public comment until Jan 22.

It requires investors to trade index futures during the trial period for at least 10 trading days and must engage in at least 20 transactions. Investors will also be asked to complete a training course and pass a test conducted by securities firms.
