Access to Timeseries and Indicator Data

These are functions for working with timeseries and indicators. A timeseries differs from the usual data array by its reverse ordering - elements of timeseries are indexed from the end of an array to its begin (from the most recent data to the oldest ones). To copy the time-series values and indicator data, it's recommended to use dynamic arrays only, because copying functions are designed to allocate the necessary size of arrays that receive values.

Function

Action

SeriesInfoInteger

Returns information about the state of historical data

Bars

Returns the number of bars count in the history for a specified symbol and period

BarsCalculated

Returns the number of calculated data in an indicator buffer or -1 in the case of error (data hasn't been calculated yet)

IndicatorCreate

Returns the handle to the specified technical indicator created by an array of MqlParam type parameters

IndicatorParameters

Based on the specified handle, returns the number of input parameters of the indicator, as well as the values and types of the parameters

IndicatorRelease

Removes an indicator handle and releases the calculation block of the indicator, if it's not used by anyone else
