supertrend

Supertrend line (ATR stop that flips with price).

Reference/Trend/Function

supertrend(atrLength, factor)

Argument order is ATR length then factor — supertrend(10, 3). That is the Dovee/chart convention, not Pine’s (factor, atrPeriod). Put ATR length and factor on input lines so they show as knobs. Color the line with mask (green while close is above, red while below) — do not paint the background. buy and sell already draw the arrow and fill price.

Parameters

Note

  • Defaults are length 10 and factor 3 if you write supertrend().
  • buy / sell already mark the bar — skip arrow, label, and paint.
  • To skip the flip bar and fill on a later high/low break, use valuewhen(flipUp, high) with barssince(flipUp) > 0. See the language tour.

Example

atrLen = input 10 as "ATR Length"
factor = input 3 as "Factor"
st = supertrend(atrLen, factor)
stUp = mask(st, close is above st)
stDown = mask(st, close is below st)
plot stUp as "Supertrend Up" green
plot stDown as "Supertrend Down" red
when close crosses above st
  buy
when close crosses below st
  sell
