When it goes up, it should go up. Don't predict whether it will go up or down, but when it comes out, if it is upward in 30 minutes, then we will make a five-minute upward swing. How to do it? Either wait until it pulls back to the pressure level, or wait until it reaches a stable point, and then wait for a wave of heavy volume to enter the market and go long. I always think too much and want to find the best target. First, find a day. Line level, then distinguish the 30-minute level upwards, and then look at the pressure level above. You can’t understand anything else, and it only adds to the trouble.
