A way to identify the Date/Time of the the first and last bar of a chart.

[efeuvejota01]

But not the rendered part, I mean the entire load of historical bars.
Thank you

Hello efeuvejota01,

The first bar on the chart is CurrentBar 0 so you could store the time on bar 0 to know the first bar of the dataset. If by the last bar you mean the last of historical that would be Count - 2 while in historical data. It could otherwise be represented as be Time[0], as the script processes the index is incremented 1 at a time and Time[0] would be the most recent bar processed. An example would be On bar 1 the first bar of the chart is CurrentBar 0 and the last bar is CurrentBar 1 because that is all that has been processed up to that point.

and the question is

to know the first bar of the dataset

?

The time of the first bar on the chart (of the data series the indicator is attached to) is Times[0][CurrentBars[0]].

Thank you Bruce!!
and how do I get the time of the last bar??

[efeuvejota01]

I made some achievements in this regard.
The following code



provides the following results... which are ok


The issue is that I need the ending time at the DataLoaded stage (Line 72 into dhe brackes of the State.DataLoaded), in order to process the indicator during the OnBarUpdate().

I know the StartTime, I know how many bars are in the chart (Input.Count) but cant´t figure out how to get the final time of the DataLoaded bars.

I think it is a Syntax issue. any suggestion??
Thank you very much!!

Hello FVJ,

Thank you for your reply.

Please clarify what you are looking for; are you looking to get the time of the last historical bar on the chart before real-time data starts processing? If so, the last historical bar on the chart may be found with the following:

if (State == State.Historical && CurrentBar == Count - 2)
{​
// this action would occur during the last historical bar processed before real-time processing begins
}

Otherwise, please provide a more concrete example of what you are looking for. Even a screenshot of a chart highlighting which bar you are referring to might be helpful so we may better understand and assist you.

We look forward to your reply.
