STARC Bands

Created by Manning Stoller, the Stoller Average Range Channel (STARC) Bands, are price ranges based on an SMA centerline and ATR band widths. See also Keltner Channels for an EMA centerline equivalent. [Discuss] 💬

chart for STARC Bands

// C# usage syntax
IEnumerable<StarcBandsResult> results =
  quotes.GetStarcBands(smaPeriods, multiplier, atrPeriods);

Parameters

smaPeriods int - Number of lookback periods (S) for the center line moving average. Must be greater than 1 to calculate and is typically between 5 and 10.

multiplier double - ATR Multiplier. Must be greater than 0. Default is 2.

atrPeriods int - Number of lookback periods (A) for the Average True Range. Must be greater than 1 to calculate and is typically the same value as smaPeriods. Default is 10.

Historical quotes requirements

You must have at least S or A+100 periods of quotes, whichever is more, to cover the warmup and convergence periods. Since this uses a smoothing technique, we recommend you use at least A+150 data points prior to the intended usage date for better precision.

quotes is a collection of generic TQuote historical price quotes. It should have a consistent frequency (day, hour, minute, etc). See the Guide for more information.

Response

IEnumerable<StarcBandsResult>

This method returns a time series of all available indicator values for the quotes provided.
It always returns the same number of elements as there are in the historical quotes.
It does not return a single incremental indicator value.
The first N-1 periods will have null values since there’s not enough data to calculate, where N is the greater of S or A.

⚞ Convergence warning: The first A+150 periods will have decreasing magnitude, convergence-related precision errors that can be as high as ~5% deviation in indicator values for earlier periods.

StarcBandsResult

Date DateTime - Date from evaluated TQuote

UpperBand decimal - Upper STARC band

Centerline decimal - SMA of price

LowerBand decimal - Lower STARC band

Utilities

See Utilities and helpers for more information.

Chaining

This indicator is not chain-enabled and must be generated from quotes. It cannot be used for further processing by other chain-enabled indicators.
