Cobra's Market View Private Messaging System shows:
The bottom line the short-term trend is down and I hold no short position overnight.
SPY down 4 days in a row, buy at today’s close and sell on the very first green day thereafter, since year 2000, you have 84% chances.
By the way, for SPX (not SPY), another down day tomorrow (i.e. down 5 days in a row), buy at close and sell on the very first green day thereafter since year 2000, you WERE guaranteed to win something.
