Initial number of bars on chart prior to loading

[gbrad]

Hi,

Is there any way within Ninja Script to find out how may bars will be loaded initially on a chart prior to the chart being loaded?

Thanks,

Hello gbrad,

As long as TickReplay is not being used you could use the Count property on any series to know how many points it has. https://ninjatrader.com/support/help...ries_count.htm

Print(Count);

If you are going to use that for any index purposes then you would need to subtract depending on the Calculate setting, with OnBarClose you would be looking at Count - 2 to get the last bar, OnEachTick would be Count - 1.

I look forward to being of further assistance.

Can't Count be examined during State.DataLoaded?

Hi Jesse,

bltdavid gets to my point. I would like to know how many bars would initially get loaded prior to hitting bar 0 in OnBarUpdate. Is that possible?

Note, I don't really need the exact number, just something near that number.

In my case, I'm not using TickReplay, but that's good to know.

Thanks,
gbrad

Hello gbrad,

What you are asking is what I provided in post 2, please try printing the Count property. You can do that on bar 0 or if you wanted in State.DataLoaded.

Please let me know if I may be of further assistance.

Hi Jesse,

Yes, that's what I needed. I tested it and it works fine.

Thank you very much.

Hi Jesse.

So, uh, what does TickReplay have to do with many 'points' in a Series?

I mean, that sounds counterintuitive -- if you want to know how many historical
bars exist in the primary data series on the chart, how does that number change
when TickReplay is used?

The link you provided does not mention a relationship between Count and TickReplay.

Hello bltdavid,

When TickReplay is enabled the bars are being built from tickreplay data so the count is not known ahead of time when used from OnBarUpdate.
