Regarding $ETH In the short term, if the amplitude narrows, you need to be more cautious about going long or short. At this time, it won’t just move in one direction; instead, it either overflows upward or drifts downward—doing so in a way that effectively extends both ends of a line segment. For example, yesterday within the past 24 hours, ETH’s highest point was 1610 and the lowest point was 1561; the amplitude was compressed into a tight range of 49 points. In that case, you cannot open positions using Fibonacci retracement. And because the time point is at the end of the month and the beginning of the month, normal rebounds will be suppressed to some extent. At this time, the price will most likely overflow toward the resistance point above 1610 and also drift down toward the support point below 1561. But you don’t know how much it will overflow versus how far it will drift down. For a low long, take profit a little earlier; for shorting, try to take profit and set stop-loss as high as possible (monitor take-profit and stop-loss at relatively low positions).
