Parabolic SAR And Price Versus Supertrend | Bots And Strategy | Help Center

These filters express current price as a signed percentage distance from Parabolic SAR or Supertrend.

What this is

- price_vs_psar_pct calculates price distance from Parabolic SAR.

- price_vs_supertrend_pct calculates price distance from Supertrend.

Both use (close - reference line) / reference line * 100 . Positive values place price above the line; negative values place it below.

When to use it

Use the zero level for trend-side or flip conditions. Use nonzero distance to require a buffer and reduce reactions to marginal touches.

Before you start

- Both filters support above , below , cross_above , and cross_below .

- Both default to value 0 .

- Parabolic SAR defaults are start: 0.02 , increment: 0.02 , maximum: 0.2 .

- Supertrend defaults are period: 10 , mult: 3 .

Step by step

Step 1: Choose the reference

Parabolic SAR accelerates as a move extends and is sensitive to reversals. Supertrend uses ATR-based bands and can be steadier when the factor is wider.

Step 2: Set sensitivity

For SAR, Start, Increment, and Maximum control acceleration. For Supertrend, ATR Length and Factor control smoothing and band distance.

Step 3: Set state or event

Use above 0 or below 0 for a persistent side. Use crossing zero for a new flip. A buffer such as above 0.2 requires price to be farther above the line.

What you should see

The result should be a signed percentage, making the same conceptual threshold more portable across different price scales.

Common mistakes

- confusing a persistent side with a one-candle crossing event

- making SAR acceleration so aggressive that it flips on normal noise

- assuming every line flip begins a durable trend

- combining both distance filters without a clear reason
