Bollinger Band Technical Analysis & Bollinger Signals
Developed by John Bollinger
Bollinger Band are formed by 3 lines. The middle line is a MA - 20 period Simple MA Moving Average.
The bands are then drawn at a distance away from the moving average These are the bands which form the lower & upper lines.
The distance where the bands are plotted is decided by another indicator known as the standard deviations. Standard deviation is a gauge of volatility in the market or that of a xauusd.
Since the market volatility keeps on changing, the standard deviations will keep fluctuating, and since Bollinger bands are drawn using the standard deviation the distance of the bands will keep on adjusting themselves to the market conditions.
When the markets become more volatile, the bands widen and they contract during less volatile periods.
The 3 Bands are designed to encompass the majority of a price action. Middle band forms the basis for the market trend, typically a 20-periods simple moving average MA.
This band also serves as the base for the upper and lower bands. The upper band's & lower band's distance from the middle band is decided by volatility. The upper band is drawn at +2 standard deviations above middle +boollinger band while lower +boollinger band is drawn at -2 standard deviations below middle +boollinger band.
XAUUSD Analysis & Generating Signals
- Bands provide a relative definition of high and low
- Used to identify periods of high and low volatility
- Used to identify periods when the prices are at extreme regions
the Squeeze
The bands tighten as volatility lessens, this identifies periods of consolidation. Sharp price break-outs tend to occur after the bands tighten.
Consolidation Pattern
the Bulge
If prices break through the upper or lower band move outside the bands a continuation of current trend is expected.
Double Tops & Double Bottoms
Bottoms & tops made outside the bands followed by bottoms & tops made inside the bands call for reversals in the trend
The Head Fake - Gold Whipsaw
Traders should be on look out for false breakouts known as whipsaws or head fakes.
Price often breaks out in one direction immediately following the Squeeze causing many traders to think the break-out will continue in that particular direction, only to quickly reverse & make the true, more significant break-out in the opposite market direction.
Traders acting quickly on the initial breakout often get caught on the wrong side of the price action, while those traders expecting a "false breakout" can quickly close-out their original position & enter a trade in the direction of reversal. It's always good to combine Bollinger bands with other confirmation Trading Indicators.
