// C# usage syntax
IEnumerable<FcbResult> results =
quotes.GetFcb(windowSpan);
Parameters
windowSpan
int
- Fractal evaluation window span width (S
). Must be at least 2. Default is 2.
The total evaluation window size is 2×S+1
, representing ±S
from the evaluation date. See Williams Fractal for more information about Fractals and windowSpan
.
Historical quotes requirements
You must have at least 2×S+1
periods of quotes
to cover the warmup periods; however, more is typically provided since this is a chartable candlestick pattern.
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<FcbResult>
- 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 periods before the first fractal are
null
since they cannot be calculated.
FcbResult
Date
DateTime
- Date from evaluated TQuote
UpperBand
decimal
- FCB upper band
LowerBand
decimal
- FCB lower band
Utilities

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.
