The recent pullback has pulled back toward the bottom of the channel. THat in itself that just alerts me that the price may be in a possible trade area. Now, the price is consolidating and will near to break back above the highs of that consolidation in order to signal a long trade and a likely rally back toward the top of the channel.
Stop Loss is placed a bit below the consolidation, if the trade triggers. An ATR Stop could also be used as a trailing stop loss, but because the price is moving in such a well-defined pattern, the trailing SL is not recommended in this case...just exit near the top of the channel.
