Moving averages and bands

The Moving averages and bands indicator provides a multi-layered trend-following framework by combining moving average ribbons, volatility expansion signals, and momentum slope tracking to identify trade entries and exits.

Usage

The Usage section describes how the script can be used to navigate different market environments:

• Trend Identification: The central ribbon, formed by the 10-period Simple Moving Averages (SMA) of high and low prices, acts as a dynamic "fair value" zone. When the price closes above the high SMA, the background turns green, suggesting a bullish shift. Conversely, a close below the low SMA triggers a red background, suggesting a bearish shift or consolidation.
• Volatility Expansion (Top Triangles): The triangles at the top of the chart track the Bollinger Band Width (BBW). Green triangles indicate increasing volatility relative to three bars ago, suggesting a potential breakout or trend acceleration. Red triangles indicate contracting volatility.
• Momentum Exits (Bottom Triangles): The bottom triangles track the slope of a 4-period SMA. These signals help traders manage exits; for example, in a long trade, a shift from green to red bottom triangles may signal fading momentum, providing an early exit signal before a full trend reversal.
• Range Definition: The Bollinger Bands provide outer boundaries for price action, helping to identify overextended conditions or potential mean reversion targets.

Details

The script integrates three distinct technical concepts to provide a comprehensive view of market behavior. The primary ribbon is based on ideas from Tim West’s "Key Hidden Levels," utilizing the high and low averages to create a channel that distinguishes between trending and consolidating price action.

The momentum component uses a short-term 4-period SMA slope, comparing the current value to its value three bars prior to determine the direction of the bottom triangles. Similarly, the volatility component calculates the Bollinger Band Width—the difference between the upper and lower 21-period bands divided by the basis—to determine if the market is entering a "squeeze" or an expansion phase.

Settings

• High MA (Internal): A 10-period SMA of the bar highs used to define the upper boundary of the fair value ribbon.
• Low MA (Internal): A 10-period SMA of the bar lows used to define the lower boundary of the fair value ribbon.
• Momentum Period (Internal): A 4-period SMA used to calculate the slope for the bottom momentum triangles.
• Bollinger Band Length (Internal): A 21-period setting used for both the volatility bands and the bandwidth calculation.
• Bollinger Band Multiplier (Internal): Set to 2.0 standard deviations to define the outer volatility limits.

FAQ

How do I interpret the background colors? The background highlights significant trend shifts. A green background appears when the closing price breaks above the 10-period high SMA, while a red background appears when it breaks below the 10-period low SMA.

What is the difference between the top and bottom triangles? The top triangles represent volatility (Bollinger Band Width) changes, showing whether the market is expanding or contracting. The bottom triangles represent short-term momentum based on the slope of a 4-period moving average.
