The initial trade below $580 closed on Tue 16 Aug when 4hr MACD crossed above its signal line with price at $570. There is no reason to remain in a trade if price action becomes indecisive so close to entry.
Can decline resume? Possibly, but the market's reluctance to trade lower than $555 implies that price must either consolidate above this level and then drop through - a wait of a week or so. Or, the market may have lost interest in selling and the upside beckons!
If so, then the structure visible in all the charts (except Bitfinex) represents a formidable base wave and could see the market turn its attention back on $680.
If additional decline becomes evident it will be analysed and tracked here.
