aytacasan, you can work with BarsPeriod Id and Value to access the interval and charttype used -

Hello,

I tryed get the chart period type like exaple but i receive an error. I think this error reason is i try to get this value in initialize method. I need this because indicator have to timeframes string parameter that user set wich time frames must work in indicator. For example user can set timeframes parameter like "233, 610". Than I try to add this time frames in initialize. How can i do this in Ninja?

Regards.

aytacasan,

Please post exact code of what you currently have and the exact error message you receive. Thank you.

I receive an error like this "you can not use BarsInProgress in initialize". However already i don't use it in initialize. I think code not compile exactly and compiler don't see initialize end sign. If you change Add(Bars.Period.Id, int.Parse(timeFrame)); via Add(PeriodType.Tick, int.Parse(timeFrame)); everything looks good but actually this is not what i want to do.

#region Variables
// Wizard generated variables
private string extraTimeFrames = "377,610"; // Default setting for ExtraTimeFrames
// User defined variables (add any user defined variables below)
#endregion

protected override void Initialize()
{
string[] timeFrames = ExtraTimeFrames.Split(',');
foreach(string timeFrame in timeFrames)
if (!string.IsNullOrEmpty(timeFrame.Trim()))
Add(Bars.Period.Id, int.Parse(timeFrame));

CalculateOnBarClose = true;
AutoScale = false;
Overlay = true;
}

protected override void OnBarUpdate()
{
// Use this method for calculating your indicator values. Assign a value to each
// plot below by replacing 'Close[0]' with your own formula.
if (BarsInProgress == 0)
{
}
}

#region Properties
[Description("Extra Time Frames")]
[GridCategory("Parameters")]
public string ExtraTimeFrames
{
get { return extraTimeFrames; }
set { extraTimeFrames = value; }
}
#endregion

Please remove your logic (loop) from the Initialize() and just try BarsPeriod.Id / BarsPeriod.Value - this should not result in any errors, if yes please send me the full script to our support email at I will give it a quick run here on my end.

Thanks

Hello Bertrand,

Sory I don't understand you exactly. But I attached my sample indicator that make up the error.

Thanks.

What I meant was try using BarsPeriod.Id instead of Bars.Period.Id - would you then see the same log entry?

[aytacasan]

Sory, i understand you now exactly. And I tryed this and yes now working my indicator.

Thanks for your help.
