This new one, I advise everyone to play for fun, don't play continuously. I tested it a few times with 5u, and you can see the K-line. Regardless of the trend or counter-trend, if you buy on the rise, it might drop after 10 seconds right before the end, and if you buy on the fall, it might directly go up in the last ten seconds. Unless you find the support point of the K-line, and you also need to have patience and fast hands.
