The classic strategy : Entry: Take a long position at the breakout of the neckline Stop: The stop is placed below the neckline Target: Theoretical target of the pattern Advantage: A lot of lows are made during the upward movement leading to the neckline so it's easy to set your stop Disadvantage: Due to an accumulation zone shaping below the neckline, the breakout can be violent and so a large part of the movement could be lost.
The agressive strategy : Entry: Take a long position at the breakout the bearish slant (example above) Stop: The stop is placed below the last lowest Target: Return on the neckline Advantage: The ratio profit/risk is high because the stop is close Disadvantage: The pattern is not yet confirmed and so the percentage of a losing trade is higher
