Trading in forex trading is often like predicting changing weather conditions. Sometimes everything may seem fine at first glance, but then unexpected fluctuations may occur.
This is where Bollinger Bands come into play and analyze the movement of the forex market and help you be aware of possible opportunities and losses in advance. For this reason, it is one of the most preferred forex trading tools by professional forex traders.
What Are Bollinger Bands in Forex Trading?
John Bollinger created Bollinger Bands in the 1980s as a trading tool to evaluate price volatility and provide buy or sell trading signals.
Bollinger Bands create an adjustable envelope that surrounds a security's price based on market movements.
BlueSuisse recognizes that success in trading requires access to essential tools. Our advanced trading platforms MetaTrader 4, MetaTrader 5 and TradeMaster provide users with numerous technical indicators such as Bollinger Bands to support informed decision-making.
What is the Bollinger Band Indicator in Forex Trading?
So, what exactly is the Bollinger Band indicator? The stock price chart shows three lines moving in response to price activity. The middle line represents a simple moving average which usually spans 20 days.
Although it may seem like a confusing concept at first, this confusion will disappear with practice or as you analyze the markets over time.
A standard deviation multiplier of two determines the placement of the upper and lower bands above and below the middle line.
The bands expand during periods of market volatility and shrink during times of market tranquility. The flexible behavior of these indicators allows traders to use them for multiple trading strategies.
These strategies may be different for each forex trader, because the currency pairs to be exchanged in the trading process are different. Determining your own unique systems is an important step when creating a forex trading strategy.
How to Calculate Bollinger Bands in Forex Trading?
We're going to focus on how to calculate Bollinger Bands. Trading platforms handle most calculations but your understanding of the formula reveals their inner workings.
Here's the breakdown:
- Calculate the Simple Moving Average (SMA): To determine the Simple Moving Average (SMA) calculate the sum of closing prices over a specific period such as 20 days and then divide that total by the number of days in the period.
- Calculate the Standard Deviation: The standard deviation quantifies the extent to which prices deviate from the simple moving average.
- Calculate the Upper Band: Add two standard deviations to the SMA.
- Calculate the Lower Band: Subtract two standard deviations from the SMA.
The formulas look like this:
- The Upper Band equals the 20-day SMA plus double the standard deviation of the 20-day period.
- Middle Band = 20-day SMA
- The Lower Band equals the 20-day SMA minus twice the 20-day standard deviation.
You can leave your calculator at rest because you won't need it. MetaTrader 4 and MetaTrader 5 both available through BlueSuisse deliver automated calculations and plotting of these bands.
How to Use Bollinger Bands in Forex Trading?
Having understood Bollinger Bands and their computation let's move forward to learn how to apply Bollinger Bands effectively. Bollinger Bands operate as your trading GPS system which aids in market navigation.
- Volatility Assessment: When Bollinger Bands widen they indicate a high level of volatility and narrow bands show low market volatility.
- Overbought/Oversold Signals: Prices that approach the upper band represent an overbought condition while prices near the lower band signify an oversold condition.
- Trend Confirmation: By examining the middle band's direction one can validate the trend's power. A band that slopes upwards indicates an uptrend in the market while a band that slopes downwards indicates a downtrend.
- Potential Breakouts: Bollinger Band "squeezes" which occur when the bands tighten together indicate potential market breakouts.
What Do Bollinger Bands Tell You About the Forex Market?
What information do Bollinger Bands provide regarding market conditions? The Bollinger Bands are sending signals about market sentiment along with potential turning points and trading opportunities.
- Price Touching the Upper Band: When an asset touches the upper band it shows signs of being overbought which may lead to a price decline.
- Price Touching the Lower Band: The asset's oversold status indicates that it may experience a price increase soon.
- Bands Widening: When the Bollinger Bands expand it indicates growing market volatility which could lead to a strong price trend.
- Bands Tightening: A tightening of the bands indicates reduced volatility and market consolidation which typically precedes a significant price movement.
