The data update of the external disk is not so fast. If you really need it, you can choose to pay, but personally think it is not necessary. The position index was originally used the day before. Want to know how to use it in real time.

The position of Mandarin History is not a ladder, at least I can guarantee that Mandarin of International Futures is definitely not, because I have been using it. Which futures company do you use? Or go to the futures company website to download the latest ones. Or adjust the index and choose CCL. If the position is still ladder, choose CJL. Can't a transaction and a position be ladder? They all overlap. What do you think?
