MQL4 Reference MQL5 features MQL5 functions Timeseries and Indicators Access

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
CopyBuffer	Gets data of a specified buffer from a specified indicator into an array
CopyRates	Gets history data of the Rates structure for a specified symbol and period into an array
CopyTime	Gets history data on bar opening time for a specified symbol and period into an array
CopyOpen	Gets history data on bar opening price for a specified symbol and period into an array
CopyHigh	Gets history data on maximal bar price for a specified symbol and period into an array
CopyLow	Gets history data on minimal bar price for a specified symbol and period into an array
CopyClose	Gets history data on bar closing price for a specified symbol and period into an array
CopyTickVolume	Gets history data on tick volumes for a specified symbol and period into an array
CopyRealVolume	Gets history data on trade volumes for a specified symbol and period into an array
CopySpread	Gets history data on spreads for a specified symbol and period into an array
CopyTicks	Gets ticks in the MqlTick format into ticks_array
CopyTicksRange	Gets ticks in the MqlTick format within the specified date range to ticks_array
iBars	Returns the number of bars of a corresponding symbol and period, available in history
iBarShift	Returns the index of the bar corresponding to the specified time
iClose	Returns the Close price of the bar (indicated by the 'shift' parameter) on the corresponding chart
iHigh	Returns the High price of the bar (indicated by the 'shift' parameter) on the corresponding chart
iHighest	Returns the index of the highest value found on the corresponding chart (shift relative to the current bar)
iLow	Returns the Low price of the bar (indicated by the 'shift' parameter) on the corresponding chart
iLowest	Returns the index of the smallest value found on the corresponding chart (shift relative to the current bar)
iOpen	Returns the Open price of the bar (indicated by the 'shift' parameter) on the corresponding chart
iTime	Returns the opening time of the bar (indicated by the 'shift' parameter) on the corresponding chart
iTickVolume	Returns the tick volume of the bar (indicated by the 'shift' parameter) on the corresponding chart
iRealVolume	Returns the real volume of the bar (indicated by the 'shift' parameter) on the corresponding chart
iVolume	Returns the tick volume of the bar (indicated by the 'shift' parameter) on the corresponding chart
iSpread	Returns the spread value of the bar (indicated by the 'shift' parameter) on the corresponding chart
