Access to the actual bars in the chart

[tadeinweilburg]

How could I get access to the actual bars data. What ist the idea behind this.

In MQL4 i can get these informations with High[i], Low[i], ... In the doc i have seen a lot of copy commands. In OOP normally i have to create an object, then access with a method or a variable of this object.

Thank you.

Open MQL5 help files. Click on MQL5 Reference > Language Basic > Event Handling Function then scroll down to OnCalculate () function like this one :

int OnCalculate (const int rates_total,      // size of input timeseries
                 const int prev_calculated,  // bars handled in previous call
                 const datetime& time[],     // Time
                 const double& open[],       // Open
                 const double& high[],       // High
                 const double& low[],        // Low
                 const double& close[],      // Close
                 const long& tick_volume[],  // Tick Volume
                 const long& volume[],       // Real Volume
                 const int& spread[]         // Spread
   );

" Parameters of open[], high[], low[] and close[] contain arrays with open prices, high and low prices and close prices of the current timeframe.The time[] parameter contains an array with open time values, the spread[] parameter has an array containing the history of spreads (if any spread is provided for the traded security). The parameters of volume[] and tick_volume[] contain the history of trade and tick volume, respectively."
