A short-term continuation pattern where price pulls back in a tight downward channel after a strong rally — usually breaks higher.
A bull flag forms after a sharp rally (the "flagpole"). Price then pulls back in a tight, orderly downward channel that looks like a flag attached to the pole. The pullback is shallow — usually just a normal retracement of the rally — and the channel slopes against the trend, which is a sign of healthy consolidation rather than reversal.
When the pullback is done, price breaks UP out of the channel, resuming the rally. The pattern works because the pullback shakes out weak hands and lets new buyers establish positions before the next leg up. The break above the upper channel line is the entry trigger.
Measured target: the length of the flagpole projected up from the breakout. A 100-pip pole + 30-pip flag means a 100-pip target above the breakout.
NAS100 printed a textbook daily bull flag in January 2024 — a 4% rally followed by a 2% pullback in a tight channel — before breaking out and adding another 5% over the following 10 sessions.
Frequently asked about bull flag
What is a bull flag in trading?+
A short-term continuation pattern where price pulls back in a tight downward channel after a strong rally — usually breaks higher.
When will I see bull flag used in real trading?+
On any timeframe after a clean trending move. Day traders look for them on 5-15 minute charts; swing traders on the 4-hour and daily.
What is the most common mistake traders make with bull flag?+
Treating any pullback after a rally as a flag. A real flag is tight, orderly, and slopes mildly against the trend. A messy, wide pullback is a correction, not a flag — and it often turns into a reversal.
What do experienced traders know about bull flag that beginners don't?+
Volume is the tell. The pole should have heavy volume. The flag should have noticeably LIGHTER volume. The breakout candle should have heavy volume again. If volume doesn't follow this pattern, the flag is probably going to fail.
