// usage IEnumerable<AdxResult> results = quotes.GetAdx(lookbackPeriods);
int - Number of periods (
N) to consider. Must be greater than 1. Default is 14.
Historical quotes requirements
You must have at least
2×N+100 periods of
quotes to allow for smoothing convergence. We generally recommend you use at least
2×N+250 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.
- This method returns a time series of all available indicator values for the
- 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
2×N-1periods will have
Adxsince there’s not enough data to calculate.
⚞ Convergence warning: The first
2×N+100periods will have decreasing magnitude, convergence-related precision errors that can be as high as ~5% deviation in indicator values for earlier periods.

Results can be further processed on
Adx with additional chain-enabled indicators.
// example var results = quotes .GetAdx(..) .GetRsi(..);
This indicator must be generated from
quotes and cannot be generated from results of another chain-enabled indicator or method.
