Breakouts and Gaps
When price levels move above resistance or below support, the change is significant. However, a momentary breakout can also retreat back into the previous trading range, meaning that the breakout fails. When a breakout is accompanied by a gap, the chances of its reversing and filling are quite high. It's all a matter of momentum. If prices move too high too fast, you have to expect a reversal.
Key PointBoth breakouts and gaps can be very meaningful. But when they occur together, smart traders know they have to pay close attention to price movement.

The price fell after this, so that the breakout failed. In this case, you would not have needed to wait very long to discover that prices were not necessarily on the move, and that the breakout lasted only a few sessions.
The same conditions prevail when a breakout takes price down below support. For example, ExxonMobil experienced a bottom-side breakout in its three-month chart, as shown in Figure below.

This breakout held. After a sideways movement of considerable time, the breakout was followed by a fairly strong downward price trend with no reversal or retesting of the previous level.
Breakouts are revealing, especially when they occur as part of a gapping action. Several gaps were present on Eastman Kodak's chart, including the first one that occurred along with a breakout above resistance, as shown in Figure below.

This first gap is not obvious because there was no space in between sessions. However, if you see that the first of the two days was black, meaning it closed at the bottom of the rectangle, then the opening of the next day gapped above that level. This set off what turned out to be a very strong breakout and uptrend.
Key PointNot all gaps are visible. Detailed analysis reveals that some of the most important gapping patterns involve gaps between up and down days, and these may be shielded because candlestick real bodies overlap.
Gaps occur often in most charts. The gap that simply occurs as a matter of normal trading but without any special signal attached is called a common gap.
Gaps are important in many different ways. The breakaway gap can be subtle and small like the one in the previous chart, or it can be very strong and wide. Its characteristic is that it moves price away from the established trading range.
When a rally takes off strongly, it is also likely to exhaust more quickly. This is not always the case, but on average you may expect to see a quick rally turn suddenly. This is especially true when the trend is accompanied by the runaway gap pattern. This is a recurring series of gaps, including consecutive gaps in two or more sessions. This is troubling because of the singular movement without slowing down, and the gapping action may drive price levels much higher or lower than the level justified by actual buyer or seller interest.
Key PointThe runaway gap pattern can be encouraging if prices are going in the direction you want. However, they also mean that the trend is likely to lose momentum quickly and reverse more strongly than trends without these gaps.
The many types of popular price patterns are valuable not so much by themselves but as part of a greater pattern and assuming that two or more indicators confirm the apparent significance of current price positions.
Beyond price patterns tracked over a series of sessions, more advanced indicators provide additional confirmation (or contradiction) and provide greater insight. These enable you to anticipate reversals before most traders know they are going to occur.
