We are about to test a long-term log trendline that was a support back in the summer 2017.
Additionally, Elliot Waves dictate that the first wave should have 0.5-0.618 retracement 80% of the time. So far we had only 0.3 retracement, not even reaching 0.382, which makes me believe that the first wave still has not finished. There are bearish scenarios where we are not even inside a wave 1, but rather wave B and will continue to new lows later, but so far it's too early to talk about them, let's assume bullish scenario.
Shorting from here and then longing from 0.382-0.5 retracement @ $650-600 seems to be a good idea.
Apart from reaching for the log trendline we also have a whole bunch of historical resistance in the zone $775-845.
It's hard to place a stop but $900 can be one (that would be above most of these resistance levels).
Entry- $820-840
Target 1: $650 (0.382 retracement)
Target 2: $590 (0.5 retracement, is also a great place to get a long)
Stop: 901
