Bollinger Bands are a technical analysis tool consist of three bands—an upper, middle, and lower band—that are used to spotlight extreme short-term prices in a security. The upper band represents overbought territory, while the lower band can show you when a security is oversold. Most technicians will use Bollinger Bands® in conjunction with other analysis tools to get a better picture of the current state of a market or security.
An Inside Bar is a two-bar price action trading strategy in which the inside bar is smaller and within the high to low range of the prior bar. Inside bars show a period of consolidation in a market. They often form following a strong move in a market, as it ‘pauses’ to consolidate before making its next move. However, they can also form at market turning points and act as reversal signals from key support or resistance levels.
