Cycle Spectrogram [LuxAlgo]The Cycle Spectrogram indicator is a spectral analysis tool that visualizes the power of various price cycles to identify dominant periodicities and market rhythms.
🔶 USAGE
The indicator provides a technical visualization of spectral density over time by decomposing price action into multiple cycle bands. This allows traders to identify whether the market is currently influenced by short-term noise or long-term structural cycles.
🔹 Spectrogram Interpretation
The spectrogram consists of 30 rows, each representing a specific cycle period. The vertical axis is logarithmically scaled between the "Minimum Period" and "Maximum Period" settings.
Color Intensity: Brighter or more saturated colors (depending on the selected theme) indicate higher spectral power or "energy" at that specific cycle length. Vertical Position: Higher rows represent longer cycle periods (slower cycles), while lower rows represent shorter periods (faster cycles).
🔹 Dominant Period Tracking
To help identify the most significant cycle at any given time, the script includes a Dominant Period Marker (red cross). This marker tracks the row with the highest energy, providing a real-time estimate of the current market cycle length in bars.
🔹 Dashboard Metrics
A real-time dashboard provides key analytical data:
Current DP: The period (in bars) of the most powerful cycle found in the current bar. Average DP: A 20-period moving average of the dominant period, useful for identifying stable, persistent cycles versus erratic shifts. Lowest Period: A reference for the minimum boundary of the spectral analysis.
🔶 DETAILS
A spectrogram is a visual representation of the spectrum of a signal as it varies with time. This script utilizes a series of Bandpass filters to isolate specific cycle lengths. Each filter is tuned to a period calculated using a logarithmic distribution, ensuring that the analysis covers a wide range of market periodicities without bias toward specific scales.
The "Power" of each cycle is calculated by squaring the output of the bandpass filter and applying a smoothing factor. This process helps filter out transient spikes and provides a cleaner "heat" signature for more reliable cycle identification.
🔶 SETTINGS
🔹 Aesthetics
Theme: Select from several high-contrast color maps, including Viridis, Inferno, Magma, Plasma, Cividis, and Turbo.
🔹 Settings
Minimum Period: The shortest cycle length (in bars) to include in the analysis. Maximum Period: The longest cycle length (in bars) to include in the analysis. Bandwidth: Controls the "focus" or resonance of each cycle band. Lower values result in narrower, more precise detection, while higher values allow for more overlap. Power Smoothing: Determines the amount of smoothing applied to the amplitude. Higher values reduce visual noise but may increase lag in detecting cycle shifts.
🔹 Dashboard
Dashboard: Toggles the visibility of the data table. Position: Moves the dashboard to different corners of the pane. Size: Adjusts the text and cell size of the dashboard.
