There are three common types of gaps that frequently occur - 1. The breakaway gap 2. Runaway gap 3. The exhaustion gap.
Breakaway gap is a more significant gap that usually marks the beginning of new trend. It occurs when the price of a stock breaks a significant resistance.
Runaway gaps typically occur during strong bull or bear markets, where the price accelerates in the direction of the trend.
Exhaustion gap occurs towards the end of a trend, signaling the exhaustion of buying or selling pressure.
