Quote from NoDoji:
That's not a very pretty daily bar here. 'Twoud be a brave buncha bulls to defend at this level even though it is near the 20-day EMA. There's a 50-day EMA around 1710 and a LTL around 1670. Those should be good defense levels.
Add to that a daily bullish engulfing pattern on the front month VIX futures and voila!
