The principle of fair-time averaging is that you can complete the total amount except the total transaction amount in the MA function of K-line. If you want to program, both Wenhua Finance and TB can be completed at present. The simulated transaction of TB is the same as the real language function and algorithm except that it can't really place an order. If it is detected, you can also place an order automatically through simulated transactions. There should be a trial version of Mandarin, but the algorithm function of Mandarin is relatively simple, which is not suitable for high-end programmatic traders. There are also gold pagodas in China, but the interface is not as good as TB.
