What is Supertrend?
Supertrend appears as a price-like line that can sit above or below price based on its volatility calculation.
Trend
Supertrend explained
Supertrend is a trend-following indicator that combines price and volatility into a directional reference line. AlertoWatch uses the documented default length 10 and multiplier 3.
How it works
The calculation uses volatility to position the reference line. AlertoWatch exposes Supertrend for supported value comparisons and crossover pairs.
How traders often interpret it
Price above the line is often read as stronger directional context, while price below it is often read as weaker context. A crossing describes a change in that relationship.
What it can be useful for
- directional trend filtering
- price-versus-line crossings
- combining trend and momentum context
- simplifying trend-state monitoring
