Every day, fans come to ask me what theory I am studying. I use the golden ratio line to provide free live teaching on-site, mastering it in no time. In the live channel, I repeatedly explain the strategies. Go long at the 0.38 support level to buy the dip, breaking through 0.618, the market enters a rising trend, testing the resistance level near 109200, and if it doesn't break on the pullback, it enters the observation area. Once the market stabilizes, the future trend indicates a breakthrough of the previous high. And those brothers above 0.38, who are bearish every day and doing shorting, remember: the trend is king, go with the flow, and trust the market!
