Futures ta is of course the code of pta, especially PTA, which is convenient for operation and memory. Zhengzhou PTA is an active star product among commodities, which is highly sought after by retail investors. 209 refers to the futures contract clause code. You must be a novice. I hope I can help you.

I recommend a futures QQ group for you: 6697295 1 all for technical exchange, and no junk pimps soliciting customers. I hope you like it.
