Increased buying interest happens all of a sudden, and the price gaps above the previous day's close. This type of runaway gap represents a near-panic state in traders.

The area near the top of the congestion area is usually resistance when approached from below. Likewise, the area near the bottom of the congestion area is support when approached from above. To break out of these areas requires market enthusiasm, and either many more buyers than sellers for upside breakouts or many more sellers than buyers for downside breakouts.
