The infamous high and tight flagpole pattern, Bulkowski's number one rated performing chart pattern. Appears on 4 hour chart. I also would suggest trading off of this chart for a longer swing style trade. Follows all the rules so far to a perfect HTFP; roughly 45 degree A to B impulse leg, tight downward sloping flag, B to C leg (or the flag itself) hasn't retraced to 36% yet, and the pattern has formed after a long downtrend.
BUY: only if the price breaks the highest high of the flag pole pattern
SELL: only if the price forms a bullish engulfing
