Newcomer's question: Why is it that there is no OKEX futures in the stock exchange, and the review is in it?

I've been studying for a few days, and I still don't understand many of the most basic questions: 1, why is there no OKEX futures to add to the exchange? or is it merged with OKEX spot? or do you need to add it manually? 2, the OKEX futures strategy template one is not found, is it because of poor support or something else? 3, which god can give a template for an OKEX futures for beginners to learn? 4, Do I need to learn how to use the inventor-quantified API and learn how to use the OKEX API? 5, Is there a QQ group or QQ of God that can guide the exchange? The main reason for the inventors' quantification is to be able to use robots to automatically trade OKEX futures and options, hopefully the answer will be straightforward!
