How does the bull flag form?
A sharp advance forms the pole. Price then drifts gently against it inside a narrow channel.
How do you confirm a bull flag?
How little ground price gives back is the giveaway. A flag that retraces most of its pole was never a pause; it was a reversal.
When does the bull flag fail?
It fails when the drift lasts too long. A flag that goes sideways for many bars has become a range, and the pole's momentum is gone.
