The AD is showing a bullish divergence on the Daily Chart, However on the weekly chart you'll notice a Bull Flag Set Up w/ a bullish Elliot Wave Count. Currently I have a C wave buy set up, but for less seasoned traders I highly recommend buying the confirm breakout.
Somethings to point out
1) you'll notice the 5th wave was rejected by the B leg of the bullish cypher pattern
2) B leg of the ABC pattern was also rejected by the B leg of the Bullish cypher pattern
3) Its important that these levels be flipped from resistances to support w/ a bullish close over both
4) I have 2 targets min. Target 207.50-$210 C leg retrace of the bullish cypher, and a Max $220 which is a X leg retrace of the bullish cypher pattern
