Sine Weighted Moving Average (SINWMA) Indicator Explained

The Sine Weighted Moving Average (SINWMA) distributes its weights along the first half of a sine wave, giving the middle of the window the most influence — similar in spirit to TRIMA, but with the smooth taper of a sinusoid. It comes from the cycle-analysis school of indicator design.

How It Works

• Weights follow a sine arc: small at the edges of the window, maximal at the center.
• The sinusoidal taper suppresses both the newest tick noise and stale data at the tail.
• The result is a very smooth line that respects the rhythm of cyclic markets.

How to Trade It

SINWMA is a natural fit for markets that swing in cycles — use it as the mean line for reversion entries, or pair two SINWMAs for crossovers with fewer noise flips. In strong one-way trends its center weighting lags, so gate it with a trend detector.

Building It in Setup.Cash

Add Sine Weighted Moving Average (SINWMA) in the strategy builder — the length input controls its sensitivity — and use its value in any entry, exit, or filter condition. You can also combine it with other tools in the Indicators Lab or via the AI indicator generator. Ehlers' Even Better Sinewave tackles cycles from the oscillator side. For the full category overview, see the advanced trend library guide.

Trend tools reward patience: pick one, pair it with a volatility or regime filter, and backtest before trading it live.
