Multi Time frame when "load data based on bars" for chart

[ct]

Scenario:

a chart is set to a number of bars to load for the primary time frame of the chart.

If i "Add" a secondary time frame what will it load?
A: As far back in time as the number of bars back for the chart
B. Same number of bars as the primary time frame even if goes back farther or less time back.
I am thinking it will do "A".

What I am wondering is if I add a higher time frame I want to go back farther in time for it but not on the base chart.
Is this possible or will the look back time for added time frames always be the same as the chart.

Hi ct, it would be the primary series you're working with setting the date range used for all series involved in the script. We have an enhancement to the Add() method on our consideration list, where you would specify the amount of data to load for each series then.

Thank for the reply. We will see if the enhancement makes it someday.

Hi,

I have still the same issue and could not find any solution for it.

Is there a new possibility in the meantime?

Thanks and best regards,

There is an enhancement on the "Add" with version 8.

Hi ct,

thanks for your quick reply and help.

I briefly checked the reference of version 8 and find the AddDataSeries() method. But I am still not sure how to use it in the way to solve the issue. Could you please give me a little bit more guidance to find the right solution?

Thanks and best regards,
Glory1

Syntax for AddDataServies (version 8):
AddDataSeries(string instrumentName, BarsPeriod barsPeriod, int barsToLoad, string tradingHoursName, bool? isResetOnNewTradingDay)

barsToLoad - An int determining the number of historical bars to load

Does this help?

I think this was your question or did I misunderstand.

Thanks ct - were you able to resolve your question Glory1?

[Glory1]

Thanks for helping me so far!

Unfortunately I am not able to understand how I can use the AddDataSeries to load a daily data set with period=x and barsToLoad=y due to the named syntax of the AddDataSeries from the reference:

AddDataSeries(string instrumentName, BarsPeriod barsPeriod, int barsToLoad, string tradingHoursName, bool? isResetOnNewTradingDay)

Where is the part for the period or how can I use the method with period and barsToLoad?

Thanks and best regards

[NinjaTrader_Bertrand]

Glory1, the period is then integrated basically into the BarsPeriod you supply in the AddDataSeries() overload call that includes the daysToLoad parameter, for example consider -

AddDataSeries("AAPL", new BarsPeriod { BarsPeriodType = BarsPeriodType.Day, Value = 1 }, 100, "US Equities RTH", null);

[Glory1]

Bertrand, thank you very much for your explanation!

Just a brief information for other users. I dont use a value within the strings. This should work with every instrument.

AddDataSeries("", new BarsPeriod {BarsPeriodType = BarsPeriodType.Day, Value = 1}, 10, "", null);

Thanks a lot to Bertrand and CT!

Is there a way to tell if the data being loaded is based on Bars, Days or Custom Range (in the Data Series dialog)?

All I could find was BarsArray[0].Count and BarsArray[0].DayCount, which does not really let me know if the data being loaded is based on Bars.

Thanks,
Greg

Greg, you could try working with DaysToLoad - this would be 0 per default if you loaded via Days or Custom Range. So if you had a number returned other than 0 from you know, you'd be in Load based on Bars mode.

Thanks Bertrand,

You got me on to the right track.

What I ended up using was:
if (ChartBars.Properties.RangeType == RangeType.Bars)
