as you can see from screenshot i am running on 5 minute bars.
however this code prints the data as 1 minute. why?

protected override void OnStartUp()
{
Print("base period id" + BarsPeriod.BasePeriodType.ToString());
Print("BarsPeriod.BasePeriodValue " + BarsPeriod.BasePeriodValue.ToString());

if(!( (BarsPeriod.BasePeriodType==PeriodType.Minute) && (BarsPeriod.BasePeriodValue ==5)))
{
// Throw warning that i got the wrong base period and this will screw up my stratgegy.
// Generates a log message with a notification window

Log("Wrong base period used", NinjaTrader.Cbi.LogLevel.Alert);

i can see from the print statements that it is thinking its running on 1 minute. why is this odd behaviour happening and how to prevent it.

Hi Junkone,

The property you're using is not for minute charts. Please see the following link:

http://www.ninjatrader.com/support/helpGuides/nt7/barsperiod.htm

You'll want to use instead BarsPeriod.Value

[junkone]

I could have a bars added using Add() leading to a multi instrument bars array, can i find out what the interval is for each of these bars array using runtime. or does it provide only base interval.

[NinjaTrader_RyanM1]

You can use BarsPeriods[ ] for accessing these properties in a multiseries context.

Trying to test for BasePeriodType.

Within a multitimeframe indicator I want to know, whether the primary bars series is time based (minute or second chart) or built from tick charts.

I therefore tested for

BarsPeriods[0].BasePeriodType == PeriodType.Minute 
|| BarsPeriods[0].BasePeriodType == PeriodType.Second

However, this condition always returned the value "true", even on tick charts. Where is my mistake?

Indicator for testing added.

Another problem I encountered, is that this indicator will produce an error message, if the tick chart has less than 3 days of data. Why is this?

Hi Harry,

These properties are what you should check for instead:

if (BarsPeriods[0].Id == PeriodType.Minute
|| BarsPeriods[0].Id == PeriodType.Second)

Thanks, that works. Did not correctly understand that help file, actually I had checked the same page as you have indicated.

Great to hear - Thank you for the followup. The properties you were using are for the special bar types - Kagi, LineBreak, PointAndFigure, and Renko.
