Ethereum's current trend gives us a very clear trading idea—look for a rebound opportunity at strong support after this wave of decline.

Let's start with entry points. The 3222 level is really interesting; it just barely touches below the Fibonacci 0.618 retracement level (around 3225), and it also corresponds to the dense volume area during the previous bottom rally (around K-line 224-240). This is the last line of defense that the bulls are desperately holding, and once it is triggered, an oversold rebound is likely to occur.

We set our take profit at 3272, which is the previous neckline resistance. The downward momentum in this wave is quite fierce, so instead of betting on a reversal, it's better to ride this correction wave and exit once the target is reached.

Place your stop loss at 3210, which is the level where the 0.618 support is effectively broken. Using 12 points of risk to aim for 50 points of profit offers a nearly 1:4 risk-reward ratio, which is quite good.

How to enter? Don't go all-in; the current downtrend is too strong. Place orders in two batches between 3225 and 3222 to prevent the market from rising prematurely or spiking suddenly.

What is the key confirmation signal for entry? If the price drops near 3222 and starts to decrease in volume, or if a long lower shadow hammer candlestick appears, that’s the signal to go in.

Once in, maintain dynamic defense. If the price rebounds to 3245 (the 0.5 retracement level), immediately move your stop loss to 3222, which becomes your break-even point. This trade either makes a big profit or breaks even—never hold through a loss.

Finally, a risk warning: if the 5-minute chart shows a large bearish candle piercing through 3220 without pause, all long plans are invalidated. Do not try to catch a falling knife in free fall.
