This topic is about the gaps in technical analysis, a gap is basically a non-trading area in the charts. The gap occurs due to the fact that something sensational happened after trading hours that triggered a bullish/bearish mentality of the traders. There are four types of gaps–1) The area gap,2) the breakout gap, 3) the runaway gap and 4) the exhaustion gap. Each gap has its own unique property in a way trend change occurs after breakout gap and the trend ends with the exhaustion gap.
