Flags and Pennants are short-term continuation patterns that form after a sharp, strong price move (the "flagpole"). They represent a brief pause before the original trend continues. Both patterns are extremely reliable because they form after confirmed momentum — you are trading with a strong trend, not against it.

Bull Flags on NSE stocks are most reliable when they form after a results-day gap-up. The gap is the flagpole. If the stock consolidates for 5–10 days after the gap without giving back much ground, the flag breakout often delivers the full flagpole distance as profit.
