$ETH This is a 15-minute chart, let's analyze what opportunities are available at the current position! As everyone knows, it is about waiting. There are four positions for trading: two short positions and two long positions. Air refueling and death cross are for trend-following, while high position retracement and bottom rebound are for counter-trend trading. Counter-trend means going against the market, which definitely requires aiming for high points. Currently, this 15-minute position clearly indicates that we can only do high position retracement, right? However, I want to emphasize high position retracement. Please pay attention to the area circled below; the movement from crossing above the zero axis back to the zero axis is a cycle. Currently, it is at the halfway point and has not completed a full cycle, indicating that it will definitely retrace to the lifeline or the zero axis. But is it suitable to short directly now? Remember, trading is about making high-probability decisions. For high position retracements, it is best to look for a top divergence pin bar to short! With the conditions set, we can watch the market to see if there are any top divergences or pin bars. Clearly, there are none! So this time for the high position retracement, we can short and wait for it to move further. If it can retrace and then rise again, while the price increases and MACD shortens or MACD energy diminishes, that is the time to short! Remember, trading is about seizing high-probability opportunities. Wait for signals that are likely to be profitable; not every signal will guarantee profits, but luck will play a bigger role in those cases! Additionally, I want to reiterate that learning is the first key. Master a complete system; do not start trading after only learning one point. You need to learn everything. Having a second runner is crucial; if you encounter any real trading problems, I will accompany you to solve them!
