Nice bullish butterfly harmonic, numbers check out.
Pattern was closed with a hammer and followed by a reversal doji.
Oversold bullish srsi crossover and rsi turning upward.
Somewhere between 3800-4600 seems likely should the sellers decide not to start selling, that should be played by ear.
Stoploss below 3150+-20 at this point.
If this reversal fails, another 50% drop seems likely in the coming months.
This is a pure technical reversal and is subject to fundamentals coming into play at any time.
Volume should be considered heavily.
