Supertrend

Supertrend is an ATR-based trailing line that changes side as price moves through its adaptive bands.

What this is

The supertrend filter returns the Supertrend line as a price and compares that line with a fixed numeric value. It does not directly test whether current price is above or below Supertrend. Use price_vs_supertrend_pct for that relationship.

When to use it

Use raw Supertrend when the calculated line itself must be above or below a known price level. Use price-versus-Supertrend for trend side, flips, and signed distance.

Before you start

- Defaults are period: 10 and mult: 3 .

- Available operators are above and below .

- The value is a fixed quote-price threshold.

- A larger factor places bands farther from price and generally reduces flips.

Step by step

Step 1: Choose the timeframe

The timeframe defines the candles and true range used by the line. Lower timeframes usually flip more often.

Step 2: Set ATR length and factor

ATR Length controls volatility smoothing. Factor scales the band distance. Tune them together, not independently from market volatility.

Step 3: Set the fixed level

Choose above or below and enter the price level for the Supertrend line. If the intended threshold is the current close, use the signed-distance filter instead.

What you should see

The raw rule passes when the Supertrend line, not current price, satisfies the fixed-level condition.

Common mistakes

- assuming raw Supertrend means price above Supertrend

- entering 0 and expecting a trend-direction test

- reducing the factor until ordinary noise causes frequent flips

- treating the line as guaranteed support or resistance
