The near-term high of SPY indicates (at the moment) that support is holding.
Near-term also is close to oversold.
If support holds then a 80% up day (on NYSE) would confirm and set-up for a retest of highs. (Go long if this happens for a reduced-risk play. AKA - buy on dip recovery.)
A *close* below 183.4 would negate bias. Expect a fall to channel low - maybe 180.
Investors could freak out on Russia - but this is unlikely. From high VIX readings fear is already worked into the market for downside protection.
