These patterns, the symmetrical triangles as well as those on the bullish and bearish side, are known to experience early breakouts that give investors a "head fake." Hold off for a day or two after the breakout and determine whether or not the breakout is for real. Experts tend to look for a one-day closing price above the trendline in a bullish pattern and below the trendline in a bearish chart pattern. Remember, look for volume at the breakout and confirm your entry signal with a closing price outside the trendline.
