Ethereum's movement tonight can be understood like this — the 3320 level is like a hurdle in a cultivation novel, a critical point from the Qi cultivation stage to the Foundation building stage. We've been stalling here for half a year, just one step away, and once we break through, we can take off directly.

From the hourly perspective, 3320 is a must-break. Once it’s broken, the upward targets become clear: 3358, 3380, and then directly to the previous high. Conservatively speaking, if this wave can stabilize above 3320, there will be a relatively considerable short-term upside potential.

But conversely, what if it can't go up? Then it will continue to oscillate within the flag pattern. The key point here is that the bottom of the flag pattern must not be broken. If it falls below the bottom, and the rebound can't get back inside the flag, then 3219 must be made up. In simple terms, the flag pattern acts as a safety cushion.

From the 4-hour cycle, the situation is a bit different. Here, a rounded bottom combined with a cup-and-handle formation has developed, and looking at the handle part alone, it’s essentially a bullish flag. Breaking this flag pattern is a signal to launch; otherwise, it will continue to sway. If it breaks downward, watch the 3273 line. If it falls below that, then 3230 and 3185 become the next support levels.

The trading idea is very simple: go long when the hourly level stabilizes above 3320, then chase on the right side, targeting 3358-3380 and the previous high. Stop-loss is placed at the flag break level. If the 4-hour level breaks below 3273, the risk is increased, and we need to consider the support levels at 3230 and 3185. The core logic is this key level: either break through and soar, or oscillate and gather strength, but the flag line is the bottom line.
