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 |
