Reading the period type of the parent chart

[shazzmoe]

Is there a way to read the chart's PeriodType?

For example, in my Initialize() I want to add a chart as follows

Add(PERIOD_TYPE_OF_PARENT_CHART, 5);


The goal here is to use a variable input for the period and always set the bars being added to match that of the parent.

Hello shazzmoe,

Thanks for the note. I am happy to help.

Inside ‘Initialize()’ we do not recommend accessing any bar series to prevent errors in cases where it can be run before you actually have a bar series. So when you ‘Add()’ to any series we recommend that it is hard coded in NinjaScript for stability reasons.

You can check the Data Series “BarPeriod” to get a period type back for use in your indicator/strategy. An example of this can be found in the following indicator linked below.

Please let me know if I can further assist you.

Thank you for the info.

One more question.

Is it possible to access chart data in the OnExecution() method from a chart other than the primary chart?

Because BarsInProgress has no relevance here I'm assuming the answer is no, but I could be wrong. I know of a workaround but want to make sure there isn't a more efficient way first.

shazzmoe, correct BarsInProgress has no relevance for filtering in OnExecution(), you can try accessing the various price arrays though available - Closes, Highs, Lows...
