straegy analyzer graph does not display the last day 'drawline' output

[joemiller]

my straegy analyzer graph does not display the last day 'drawline' output even though the output window shows valid plottable values for that day? [ie] i was expccting the 'OnBarUpdate' script code to be executed that one last time but that apparently does not happen?
is that to be expected or am i probably doing something wrong? is there a work-around if my code is ok?

CORRECTION to my original post

CORRECTION
the output window shows data only up to the next to the last day. but still, my question remains the same [ie] shouldn't the 'onbarupdate' code have been executed on the lastday?

Hello joemiller,

Thank you for your post.

I see the same behavior on my end. While a trade can be closed on the last bar and even Print() can be called on the last bar, the Drawing Objects do not appear to draw on the last bar of the backtest.

I will follow up with development on this item and follow up with you here with additional information.

Thanks a whole lot Patrick, that takes a load off me.
I was just about to send the following message, which just says I am still investigating the problem and in addition confirms what you just said [ie] that the Print() function works fine on the last day.

below is the message I was about to send-------
"after considerable debug coding I am confident that the 'onbarupdate' code is not working properly on the last day. display of the last day's info is the crucial info needed for the following new day.
I am going to put additional code in the 'onbarupdate' code to see if maybe it is being entered on the last day but 'drawlines' are not being completed. seemingly unlikely but it's worth further investigation." the Print() function works for the last day.

every drawline object is displaced one bar to the left ?

it appears that every drawline object is displaced one bar to the left [eg] when I tell it to
draw a segment from one bar back to the current bar it draws it from 2 bars back to one bar back...which might explain why there is no drawline object on the last day.
i'm not sure about all that. I am super busy with other things at present but will get on it again soon as possible to check it out some more. just want to give an alert about what I think I have seen.

Hello joemiller,

Thank you for your reply and for this information. This is expected behavior.

OnBarUpdate is called when a new bar appears and is being created and not when a bar closes. (Typically both happen at the same time).

However, since there is not a new bar that is being opened the last OnBarUpdate call never happens for the last bar.

Changing the script to CalculateOnBarClose false, allows the OnBarUpdate to call for the last bar.

However, changing CalculateOnBarClose will introduce things that must be addressed in the script such as which bar is BarsAgo 0.

Below is a link to the help guide on CalculateOnBarClose.

Also, I am including a link to the help guide on Multi-Time Frame & Instruments. In the section 'How Bar Data is Referenced' there is information about BarsAgo.

Please let me know if this does not resolve your inquiry.
