A doji candlestick pattern at a confluence level marked by previously established resistance, the 50 SMA, and the 200 EMA. Short at 538, stop at 600, target profit 400 at least. I'm not in this trade as I'm not a BTC trader -- and I'll most likely be participating in it from the long side if I ever do -- but I am watching price action and journaling my thoughts to get a feel for it.
