Some moves get too hot to chase, and this one is definitely cooking. Buyers still have control on $ARM, but the better play is waiting for the pullback around the 319 area.

Entry: 319.17 - 319.94
TP1: 322.06
TP2: 323.37
SL: 318.63

The 15m structure remains firmly bullish, while the 1h and 4h are still pushing higher with strong momentum. OI has dropped 3.2% as price climbed, so the next reaction around support should be where the real battle shows up.
