FFT Dominant Cycle Finder estimates the current dominant market cycle length from recent price action using an FFT-based spectrum scan.
Use it to:
- Choose adaptive periods for oscillators, RSI, stochastic, moving averages, or cycle tools.
- See when the market rhythm is shortening or stretching.
- Compare raw dominant cycle changes against a smoother cycle line.
- Feed EA logic with a cycle-length buffer instead of a fixed period.
What it shows:
- Cyan line: raw FFT dominant cycle estimate.
- Gold line: smoothed dominant cycle estimate.
- Hidden strength buffer: how dominant the peak spectrum component is versus the rest of the scan.
Main features:
- Standalone dominant-cycle indicator.
- FFT logic based on the existing MetaCoderStore cycle finder code.
- Configurable FFT window: 64, 128, or 256 bars.
- Minimum and maximum cycle filters to remove unusable extremes.
- Optional linear-drift removal before the FFT scan.
- EA-readable buffers.
Basic use:
- Add the indicator to a chart.
- Watch the cyan line for the current dominant cycle length.
- Use the gold line when you want a steadier period input.
- Apply that cycle length to your oscillator, moving average, or adaptive strategy settings.
Inputs:
- MaxCalculatedBars : limits how many historical bars are calculated.
- BarsToAnalyze : FFT window length. Use a power of 2 such as 64, 128, or 256.
- MinCycle and MaxCycle : visible cycle-length range.
- SmoothPeriod : smoothing length for the gold line.
- PriceSource : price series used for the FFT scan.
- RemoveLinearDrift : removes straight-line price drift from the FFT window before scanning.
Buffers:
- Buffer 0: raw dominant cycle.
- Buffer 1: smoothed dominant cycle.
- Buffer 2: dominant peak strength.
Risk note: this indicator is a technical analysis tool. It does not guarantee profitable trades. Use it with risk management and additional confirmation.
Signals
- Green arrows in the oscillator window mark a meaningful dominant-cycle expansion.
- Red arrows mark a meaningful dominant-cycle contraction.
- Signal buffer values: 1 expanding cycle, -1 contracting cycle, 0 no signal. The strength filter helps avoid weak FFT changes.
