load more data with AddDataSeries() than in the chart

[sidlercom80]

Hi, I try to access values older than those shown in the chart using the AddDataSeries() method in my chart (10 days loaded in chart).


how can I load more days in the data series than in the chart? I try the following:

AddDataSeries(Instrument.FullName, new BarsPeriod { BarsPeriodType = BarsPeriodType.Day, Value = 1 }, [B][COLOR=#e74c3c]365[/COLOR][/B], TradingHours.Name, null);

unfortunately only about as many days of data are loaded as shown in the chart, although I have specified 365 days

Print(BarsArray[1].Count);

does not result in 365 but the same number as bars can be seen (loaded) in the chart. how can I load on the 365 days in the second data series?

Hi sidlercom80 ,thanks for writing in.

I am able to load 365 days on my test script. I loaded up a 1 minute chart and, 5 days loaded for the primary series and loaded 365 days of daily bars. Could you test this out and check the output window?

I look forward to assisting.

Hi _ChrisL, thank you for your answer. up to the timeframe 60 minutes it goes, from 1 day no more, see pictures:



any idea?

I forgot I use:

Print(Times[1][0] + " " + BarsArray[1].Count);

Hello, thanks for your reply.

Are you connected to a data provider that is giving the NQ instrument? Try restarting the platform, connecting to your data provide and test the script again. There should be no issue with this method.

Best regards.

Yes I`m connected, I also made a reboot. ;-)

here is a small video: http://www.youtube.com/watch?v=KTelRMDZ-Mo

anything higher than intraday, the set 365 days will not be loaded


it seems as if it just doesn't work if the same timeframes are in the AddDataSeries AND chart.

Hello sidlercom80, thanks for your reply.

It's because you are using the same data series as the primary. You will need to load the number of days for the chart if you use a daily series on the chart. This is expected due to the note on the AddDataSeries page:

When adding multiple Data Series of the same instrument and the same Bar Type, the 'barsToLoad' property will only be effective on the first added series. Subsequent series with a different barsToLoad setting will not load a different number of bars then the first series.

Please let me know if I can assist any further.

Thank you for your explanation! I've probably read that over

Hello Chris_L,

I was able to get it working for my use case. However, I had to change the TradingHour.Name to "Default 24 x 7". While it works that's a hard coded value. Is this ok?

Did a little guess work and came up with the value, Instrument.MasterInstrument.TradingHours.Name. This appears to work. Perhaps TradingHour.Name is deprecated. Can this be confirmed?

Secondly, is the 365 days the max value? Can this be larger? Practically it doesn't. I thought about making it user definable but the documentation said to avoid this. A 365 day max would cap how far out the indicator can make calculations, but I don't see anyone pushing the period past 50 days.

Best regards,

Hello Unsuitable,

This is fine to do, however note the session close times may not be what you expect, which can cause bars to form differently.

Are you looking for Bars.TradingHours.Name? ( or BarsArray[1].TradingHours.Name)

There isn't a limit to how much data can be requested, but this would be limited by the amount of data available from the provider.
With NinjaTrader Brokerage there is 1 year of tick data, minute data as far back as recorded (typically 10 years), and day data as far back as recorded.
