Learn to hold positions with 136 when entering the market; it is easier to maintain positions during volatile markets! 136 can both attack and defend! There is only one direction; watch for an hour's cycle of rising, and during fluctuations, just determine the opportunity to add positions around 4600 after confirming 100 points—this process can be ignored! And there aren't that many positions! Don't gamble on every one or two-minute fluctuation; this can easily lead to exiting the market!
