Using ChartBars to reference another chart

[LunaKai]

Hello,

I have a 1 min chart that references a 100 tick chart using

AddDataSeries("NQ 03-25", Data.BarsPeriodType.Tick, 100, Data.MarketDataType.Last);

Based on some search results, it appears as though if I want the high of the next-to-last completed bar on the 100 tick chart, I could use this:

if ChartBars[1].High[1] > some calculation...

But when I try it, I get CS0021 "Cannot apply indexing with [] to an expression of type 'ChartBars'.

I'm probably missing something obvious here, but I can't find any examples of using ChartBars to reference another chart's bar properties anywhere other than that one above in bold.

Any help would be much appreciated.

Thank you!

Hello LunaKai,

ChartBars refers to the primary series, its not something that is indexed. You can use Highs[1][0] to get a secondary series value that you added in code. The 1 would be the bars in progress for the series you wanted to access and 0 is 0 bars ago.

Brilliant, thank you!

Hi, i have another question... if want to use multiple instrument data. for example setting the strategy up on an MNQ chart, but using also the MES data, how can i efficiantly call the MES data always using the latest contract dates? I have this, at the moment

AddDataSeries("MES 03-25", Data.BarsPeriodType.Minute, 2);

it works, but i don't want to change the dates manually

Hello konganda,

With secondary series you will need to change the dates, there is no way to inherit the current contract date as a variable for secondary series.
