There are relatively few domestic futures companies. As far as I know, even domestic futures companies are doing more in the European market.

When it comes to transactions, many of them are small companies now. If there is a broker, there is definitely no job of pure trading. Moreover, there are no trading operators in China's securities companies at present. There seems to be some in Hong Kong.

I suggest that you can introduce some individual companies through your former colleagues. Then gradually get to know more people, or if you are famous yourself, you can also talk about your previous work and place. I know several places where domestic transactions are famous now, such as Xiamen. If you are a trader in these companies, it should be easier to find a trading job.
