MA and SMMA with Bollinger Bands

Sliding Average with Bollinger Bands

General Information: The indicator combines two popular technical analysis tools:

• Moving Averages (Simple Moving Average and Smoothed Moving Average) to assess the trend.
• Bollinger Bands to analyze market volatility.

Main Components:

1. SMA (Simple Moving Average): The simple moving average is calculated as the arithmetic mean of prices over a specified period.

Formula:

𝑆𝑀𝐴 = (𝑃1 + 𝑃2 + ⋯ + 𝑃𝑛) / 𝑛

Where:

• 𝑃1, 𝑃2, …, 𝑃𝑛 are the closing prices for 𝑛 periods,
• 𝑛 is the number of periods.

Features:

• Quickly reacts to price changes.
• Used for short-term trend analysis.

2. SMMA (Smoothed Moving Average): The smoothed moving average takes into account the entire previous price history, minimizing fluctuations and market noise.

Formula:

First value: 𝑆𝑀𝑀𝐴1 = 𝑆𝑀𝐴

Subsequent values: 𝑆𝑀𝑀𝐴𝑡 = (𝑆𝑀𝑀𝐴𝑡₋₁ * (𝑛 - 1) + 𝑃𝑡) / 𝑛

Where:

• 𝑆𝑀𝑀𝐴𝑡₋₁ is the previous smoothed average value,
• 𝑃𝑡 is the current price,
• 𝑛 is the number of periods.

Features:

• Responds more slowly to price changes.
• Suitable for long-term trend analysis.

3. Bollinger Bands: Bollinger Bands are calculated based on the moving average and standard deviation, indicating the range of price fluctuations.

Formulas:

Upper band: Upper BB = MA + (StdDev * K)

Lower band: Lower BB = MA - (StdDev * K)

Where:

• MA is the moving average (SMA or SMMA),
• StdDev is the standard deviation over 𝑛 periods,
• K is the standard deviation multiplier (default is 2.0).

Features:

• Bands widen when volatility increases.
• Narrow bands indicate low volatility.

Indicator Parameters:

• len (SMA Length): Determines the number of periods for calculating the simple moving average. Example: If len = 9, the indicator will consider the last 9 bars for calculating SMA.

• maLengthInput (Smoothing Length): Determines the period for calculating the smoothed moving average (SMMA). Example: If maLengthInput = 14, the indicator smooths values based on the last 14 bars.

• bbMultInput (Bollinger Bands Multiplier): Indicates how many standard deviations the upper and lower bands are away from the mean. Example: If bbMultInput = 2.0, the bands will be at a distance of two standard deviations.

• maTypeInput (Moving Average Type): A dropdown list for selecting the type of average:

  • SMA: Simple Moving Average.
  • SMMA: Smoothed Moving Average.

Advantages of the Indicator:

• Flexibility:

  • Ability to choose between SMA and SMMA depending on market conditions.
  • Bollinger Bands automatically adjust to volatility.

• Trend and Volatility Analysis:

  • Moving averages help determine the trend direction.
  • Bollinger Bands identify overbought/oversold zones and changes in volatility.

• Ease of Adjustment:

  • All parameters are intuitive and easy to adjust.

How to Use the Indicator:

• Trend Analysis:

  • The SMA/SMMA line shows the overall direction of the price:
    • Uptrend: Price is above the average, and the line is directed upward.
    • Downtrend: Price is below the average, and the line is directed downward.

• Working with Bollinger Bands:

  • Price close to the upper band: Possible overbought zone, signal to sell.
  • Price close to the lower band: Possible oversold zone, signal to buy.
  • Bands narrowing: Indicates low volatility, potential impulsive breakout.

• Smoothing (SMMA):

  • Use SMMA for long-term trends to avoid noise.

Example Usage:

• SMA (9) and Bollinger Bands (K = 2.0):

  • Suitable for short-term strategies.
  • Quickly reacts to trend changes.

• SMMA (14) and Bollinger Bands (K = 2.0):

  • Suitable for long-term analysis.
  • Smooths out short-term fluctuations.

Conclusion: The "Sliding Average with Bollinger Bands" indicator is a versatile tool that combines trend and volatility analysis, making it suitable for a wide range of strategies. With flexible settings, the user can adapt the indicator to their needs, whether for short-term trading or long-term analysis.
