If you keep getting stuck in contract trading and can't stop looking at the K-line, and you feel like shorting when it rises too high, or going long when it falls too much, I suggest you watch the Ant Battle. There is no such mindset here—only the amount of long and short ants. There are more green ants, so you never go short. If there are too many red ants, you never go long. Combine it with the K-line, and it should help improve your contract win rate!
