SPXEW $3228.86 upper 21,2 daily BB vs. 3229.59 day high, so far
3228.56 = the March daily close low
* be alert for a potential BB tap and down, which may play out from this upper level
* FYI - it will be a bullish clue for some more upside only if the Bollinger Band continues to expand, and SPXEW actually closes today above the upper Bollinger Band
