Bollinger Bands can be an excellent way to complement other indicators and chart patterns, helping clarify technical patterns such as M tops and W bottoms.
The bands consist of a center line with two outer bands positioned two standard deviations above and below it, usually two standard deviations away. Their width can be tailored according to each trader’s strategy.
Trend Reversal
Bollinger Bands consist of a moving average with upper and lower bands set a certain distance above and below it, set by standard deviations from center line. Bollinger Bands are designed around the assumption that prices tend to revert back towards their median values while volatility tends to follow a normal distribution.
As such, traders use Bollinger Bands to identify trends and potential price reversals. When prices move close to either of the upper or lower bands, this suggests that security could be overbought or oversold – conditions which could signal a trend reversal in either direction.
Bollinger Bands are lagging indicators that react rather than predict price movements, meaning false signals can occur during periods of high volatility or when bands expand. Therefore, traders should always combine Bollinger Bands with other technical analysis tools in order to verify signals and reduce errors.
Consolidation
Bollinger Bands can assist traders in recognizing potential trading opportunities; however, to increase effectiveness and help achieve financial goals more quickly. They should be combined with other tools and indicators to optimize effectiveness and decision-making capabilities for maximum impact.
These indicators work on the assumption that volatility tends to follow a mean-reverting pattern, thus including a center line representing an average and two bands set a certain distance from it. Traders can customize these bands according to their strategy but the default settings include 20-period SMA with bands separated by two standard deviations.
The width of the bands provides insight into market volatility; when narrow bands indicate low volatility while wider ones indicate increased uncertainty.
Overbought
Bollinger Bands are widely used among traders to identify overbought forex pairs and gauge when the price may turn. The middle band represents the simple moving average (SMA), while upper and lower bands are set a certain number of standard deviations above or below this SMA; traders often believe that when price moves above either upper or lower bands it signals either sell or buy signals respectively.
As volatility increases, the gap between bands widens; when prices move closer to either of the upper bands many traders believe they are overbought and may need correction or reverse; conversely if prices move closer to either of the lower bands it could provide great buying opportunities.
Oversold
Bollinger Bands can serve as dynamic support and resistance levels in many trading strategies, due to their tendency for volatility to mean-revert and prices staying within its boundaries.
Traders recognize prices nearing the upper band as being overbought and should consider them candidates for price correction, while those closer to the lower band might need some form of price reduction before rebounding.
Squeezes occur when bands narrow, signaling reduced volatility and an imminent potential breakout. At such times, traders should use momentum indicators to confirm an impending trend change while volume indicators provide insights into its strength.
Double Bottom
Double bottom chart patterns are reliable indicators of an impending trend reversal and should be visible on a weekly, monthly or yearly chart. They typically work best when stable markets or moderately trending markets exist, though to recognize a double bottom requires careful observation of index price movement as its volume rises while developing.
Although both Double Bottoms and their counterpart, Double Tops, are reliable reversal patterns, they’re often misunderstood when trading them based on them alone can be risky. A successful Double Bottom is formed when two lows separated by an elevated peak create an inverted “V”, known as its neck line; both lows should fall within 3% to 4% from each other for proper formation of this pattern; breaking above its neckline signals potential gains of 10% or more for trading this pair.
