How to call the Last Session's Close

[pstrusi]

Hi Ninjas,

Everytime I begin a code for a new session, I need to do a one time calculation:

The difference between the Last Session's Close minus the very first Close[0] of the new session. Searching in the help guide, I've known this interesting method: Bars.GetDayBar(1).Close which, supposedly it will have that last session Close that I want to find. So I did a little snippet to be run under OnStartUp() method, this is as follows:

if ( (Close[0]-Bars.GetDayBar(1).Close) >= 0 )
{
	// Do something
}
else
{
	// Do otherwise
}

Here's my doubt:

In Forex a new session begins at 17:15 hours, so the method Bars.GetDayBar(1).Close, would really give me the the very Last Close at 17:00 of the PAST last session?

If not, please would you indicate how to address it correctly?

Thanks

Hello,

Thank you for the question.

Are you just trying to get the Prior sessions close? If so, you could use the PriorDayOHLC indicator to do this rather than re creating all new logic.

The syntax to get the Close would be:

double value = PriorDayOHLC().PriorClose[0];

Also this would need to be called after OnStartUp as OnStartUp is happening prior to the bars being processed on the chart. This can go anywhere in OnBarUpdate or the other override methods that happen after OnStartUp.

I look forward to being of further assistance.

Thanks for your response Jesse, it seems that your solution is what I was looking for. I'll try it.

Thanks again and best regards
