Thanks Matt.  The thing I find interesting is that you know how $NYSI crossed below the 9ema in early Jan when the S&P 500 was around the 4700 level- well if one were to wait for the candle confirmation, they would've had to wait until $SPX closed below that 4700 level (which hasn't happened as you pointed out and thus led to the current divergence on the chart).  But since there was that TINY positive cross on 2/1 and then a negative cross on 2/2 (the low for $SPX being at 4907.99), now the threshold for confirmation of the SELL signal is now at 4907.99 and not at around the level 4700 level anymore.  Would love to see how it plays out.
