sharing data

[futurenets]

as anyone shared bar data (or any structured data array) between charts?

I realise bar objects can be added to scripts with different intervals but sometimes
the bars numbers required are vastly different so looking for more efficient way
to share bar/indicator data?

looked at c# memory-mapping but can't find a suitable example.

Hello Futurenets,

Thank you for your note.

You can take a data series and make it public so that you can have access to it from the other scripts

ok thanks

downloaded sample and can see

private DataSeries myDataSeries;

but unsure how changing this to public will make data available bewteen charts?

unless I create

public DataSeries myUniqueName;

and can then reference it from other scripts but only one instance could exist?

say I wanted to create

Daily EURUSD and make data available to 15minute EURUSD

Daily GBPUSD and make data available to 20minute GBPUSD

etc.

or put something like

namespace NinjaTrader.Indicator
{
partial class Indicator
{
Public DataSeries dailyGBPUSD;
Public DataSeries dailyEURUSD;
}
}

in UserDefinedMethods?

but how would it know which chart interval to sync to?

Futurenets,

I apologize I sent you the wrong reference sample. You set the property for public in the Properties section

This is the one that you want -

This will show you how to expose the data series.

Additionally for syncing to a different time see this one -

Let me know if I can be of further assistance.

[futurenets]

ok thanks.

I think what's confusing me is how a chart can access a public data series of another chart?

[NinjaTrader_CalH]

Futurenets,

After you call the class -

MyClass().MyDataSeries[0]

Same concept if you were getting the Diff value of MACD -

MACD(12,25,9).Diff[0]

[futurenets]

ok Cal thanks but

where did MyClass come from and what is it?

[NinjaTrader_CalH]

I was using it as an example script to use. Nothing that is real.

[futurenets]

ok thanks but confused

let say I have a 15minute chart that needs to access data in a daily chart.

how is this done in the script running on the 15 minute chart?

[NinjaTrader_PatrickH]

Hello futurenets,

Thank you for your response.

You would create a script that runs on the other chart (the daily in this example) and then expose that data series - making sure it is synced to the primary series in the script and set to the desired value.

For example:
MyDataSeries.Set(Close[0]);

[futurenets]

ok thanks Cal. to clarify...

in the Daily chart I set MyDailyDataSeries to the required values and expose with "public".

in my 15 minute chart I can then simply reference MyDailyDataSeries[0] and retrieve a value from this series?

if I have several daily charts running how do I know which one I'm using?

[futurenets]

thanks Cal for your patience. got everything I need now.
