The neckline is formed by connecting the lows of the two valleys, and a break below the neckline is seen as a bearish signal.

In technical analysis, a gap refers to a price area on a chart where no trading activity has occurred. There are three types of gaps: the common gap, the breakaway gap, and the runaway gap. Common gaps occur within the price range of an asset and can often be ignored. Breakaway gaps occur at the beginning of a trend and are usually accompanied by high volume, while runaway gaps occur in the middle of a trend and indicate a continuation of the trend. Traders may use gaps to identify potential support or resistance levels and make trading decisions based on them.

An island reversal is a technical chart pattern that occurs when the price of an asset has a gap up or down, followed by sideways trading, and then another gap in the opposite direction, forming an "island" of prices. This pattern is a potential signal of a trend reversal, with the "island" acting as a resistance or support level. Traders may look to sell or short the asset if the island reversal forms after a bullish trend, or buy the asset if it forms after a bearish trend. However, like all technical analysis patterns, traders should confirm the signal with other indicators or analysis techniques.
