$SPXEW daily chart has met the initial criteria for an M-top using:
the 21,2 %B and the 50,2 %B setups
since the $SPXEW printed a higher price high in July above the June high, while the two %B's closed far below the 1.0 line at the time of the higher July price high
* similarly, the M-top initial chart criteria has been satisfied for the SPY daily chart and the RSP daily chart …. chart vigilance is prudent until the upper Bollinger Band is actually reached or surpassed by a higher price high above the June high and the current July high
"M-Tops were also part of Arthur Merrill's work that identified 16 patterns with a basic M shape. Bollinger uses these various M patterns with Bollinger Bands to identify M-Tops. According to Bollinger, tops are usually more complicated and drawn out than bottoms. Double tops, head-and-shoulders patterns, and diamonds represent evolving tops. In its most basic form, an M-Top is similar to a double top. However, the reaction highs are not always equal. The first high can be higher or lower than the second high. Bollinger suggests looking for signs of non-confirmation when a security is making new highs. This is basically the opposite of the W-Bottom. A non-confirmation occurs with three steps. First, a security creates a reaction high above the upper band. Second, there is a pullback towards the middle band. Third, prices move above the prior high but fail to reach the upper band. This is a warning sign. The inability of the second reaction high to reach the upper band shows waning momentum, which can foreshadow a trend reversal. Final confirmation comes with a support break or bearish indicator signal. "
