After the successful Bullish Bat buy signal, which brought about the end of the wave II correction in ETH, there is now a potential Bullish Butterfly forming. (see related ideas below)
If this plays out, we get a completed Bullish Butterfly harmonic pattern in Ethereum at 537, which also happens to be the 61.8 retracement of wave 1 (0f cycle wave III up). This should signal the start of wave 3 up. Even if this pattern doesn't complete, it looks like ETHUSD is close to completing wave c)) of 2. So, either way, wave 3 up should be starting soon.
