Last Historical Bar?

[ninZa]

I see. Your answer was tied to the scenario in the asked question.

By the way, what is the meaning of Osikani? Can you explain it to all the people here.

Thank you Koganam.

Please check it Koganam.

Yesterday I played with both of them. Changing COBC to false increased the value of LastBarIndexPainted by 1 (for the actual last bar on chart). So LastBarIndexPainted is dependent on COBC.

Just from the logic, we can also tell that a thing related to ChartControl (ChartControl.LastBarPainted) cannot be dependent on COBC.

Granted the truth of what you are saying if the CurrentBar is the last bar being displayed on the chart, I was answering the thrust of the original question, which wanted to know the index of the "last bar showing on the right" if the chart was somewhere in the middle. Given that, I did not go into the niceties of what happens in the edge state, as that is not what the original question was about.

Put the display into "threaded" mode, and you will see that that is the question to which I was responding.

Could be, but I am pretty sure that what I wrote is correct.

My skill is googling Koganam lol.

Regarding your comment about the dependence on COBC, should we reverse the order? I mean the 1st one (ChartControl) should be absolute, and the 2nd one is dependent on COBC?

Though, given his skills, Ninza may have come upon that independently.

BOOM! Worked a charm. Where did you pull that one from?

Thanks.

It works actually? I'm not sure, so I gave you another solution above.

I don't remember where I got the info of LastBarIndexPainted. Perhaps searched something on Google and found it.

Great stuff. Thanks again

marty087, please try LastBarIndexPainted. I'm not sure this works in your case. This will give you the last bar painted on chart after the bars are loaded. In your case, you want to get the value in advance, so I'm not sure. Please test it, if it doesn't work, we will have to take another approach.

Thanks.

In short....

CurrentBar returns the id of the last bar displyed on the right of the screen irrecpective of whether the chart is scrolled to the end or not.

Count OR Bars.Count returns how many bars are in the chart once fully loaded / scrolled to the right alll the way

So..... if i am in the middle of the chart and want my indicator to only execute once it has arrived at the furtherest scrooled bar, is there any way to do this?

FREEN, is it fair to say that the supplied code below (Bertrand's contribution) didnt provide a solution for you?

Cheers Guys.

marty087, when you are in the middle of the chart, the indicator will only execute until the last bar printed on your chart and then it will temporarily stop there, until a LIVE tick comes in. If there are no live data coming in, the indicator will not reach the actual last bar (whose index is Bars.Count - 1). You have to manually scroll your chart back to the actual last bar. This is my 30-minute inspection on the issue, need a confirmation from NT staff.

However, if in a live market with fast coming data, you can execute the following unsupported codes to ignore all bars until the last painted bar:

if (ChartControl.GetXByBarIdx(BarsArray[0], CurrentBar) < ChartControl.CanvasRight) return;

Can you clarify the meaning of "scroll point"? A screenshot with your notes on it will easily explain.

See pic for clarification

Scroll point in the sense last bar on screen, that might not be bars.count.

HI Guys,

I would like to do exactly what Freen has requested here.

Then you are not doing exactly what Freen is doing.
