How can I get the index position of a specific Datetime?
29 Mar 2013, 20:17

Is it any function or an other way to get immediatly the index position of a specific Datetime?

In MT4 i use the function:

iBarShift(NULL,0, time)

So if I want to get for any bar the close price of the 1st bar of the day I use the following code:

datetime CurrentTime = Time[j]; // Current Time
int BarsCurrentTime = iBarShift(NULL,0, CurrentTime); // Bars Current Time

datetime TimeStartOfDay = CurrentTime - CurrentTime % 86400; // Time Start of Day
int BarsStartOfDay = iBarShift(NULL,0, TimeStartOfDay); // Bars Start of Day

MaCounter = BarsStartOfDay - BarsCurrentTime;

close = iClose(NULL, 0, MaCounter )

In cAlgo I can get the first bar of the Day for any bar with the next code:

MarketSeries.OpenTime[index].Date

But how can I convert the Datetime to index position ?

Thanks in Advance

The index is just :

MarketSeries.Close.Count-1

And the index value of:

MarketSeries.OpenTime[index].Date

is the same variable index used to get the open time you are requesting

hope this helps buy maybe I am not understanding you question...

You can now access it easier with the GetIndexByTime or GetIndexByExactTime methods:

DateTime date = MarketSeries.OpenTime.LastValue.Date;
var firstBarIndex = MarketSeries.OpenTime.GetIndexByTime(date);

How do I get the close at a specific time each day, i.e., 1700 hours or 0230 hours?

var dateTime = new DateTime(2019, 5, 10, 17, 0, 0);
Print(MarketSeries.Open[MarketSeries.OpenTime.GetIndexByTime(dateTime)]);
