Want to test Chart Bar Type... How?

[saroj]

I have an indicator that adds 2 additional bar periods as follows...

Add(PeriodType.Range, 12);
Add(PeriodType.Range, 24);

I now want to adapt this for a tick chart. How do I test to see what the PeriodType is?

(couldn't find anything in the help)

Thanks,
Saroj

Hi saroj,

You can add tick series using Add(PeriodType.Tick, 1000);

You can identify the interval type of a chart using BarsPeriod.Id, but this property should not be accessed in Initialize, where you need to add series.

thanks ryanM... yes I saw that but don't see how to construct the test...

so if I have to Add the bars in the initialize section, but not allowed to test for what's on the chart there... how do I construct the "Add" statement so that it only adds tick bars to a tick chart and minute to a minute, etc.?

Right - the primary series is not available at the time the script needs to add. We only support hard coding additional series.

[saroj]

can I use an enum definition for the user to select a bar type and then do a conditional on the "Add" statements or is that not available in the Initialize section?

[NinjaTrader_RyanM1]

We support only hard coding any additional series, but some users reports success with inputs and an enum may work as well. You're free to try but will be on your own to verify everything works as you expect and resolve any potential issues.

Ryan, if I want to try this what is the correct way to test the BarsPeriod.Id value?

I doubt the following is correct, but just to show you what I'm trying to do.

if (BarsPeriod.Id == "Range") Add(PeriodType.Range, addBarPeriod1);

saroj,

Unfortunately we would not be able to offer any advice on this. However we will leave this thread open for other users to comment.
