i am adding SHW as both an active trade, as a short from current levels, as well as a set-up for an entry (or add-on) on a break below the channel AND horizontal support (both must go).  shorting inside of a powerful uptrend channel like this is for aggressive traders only (complete counter-trend trade plus still within the pattern).  however, my own style is aggressive and i often do well by anticipating when patterns that are getting long in the tooth are ready to break down (or up).  of course, shorting near the top of this channel with a stop above the recent highs is relatively low risk (minimal downside before your stop) and seems fairly objective from a R/R standpoint, considering the downside potential if this trade starts to play out.  lots of thin air once/if the channel breaks down before the final target (T2 is hit).
