NT7 - How does Global Variable functionality work between charts

[mefTrader]

Hi,

I have an indicator applied to a 5min chart and another 15min chart (different chart window). How do I access data from the 5min chart on the 15min chart (or vice versa). I was led to believe that would be a new feature for NT7?

I have found the following post with regards to using GV.dll similar to what is used on Tradestation but have not used this yet (also this is probably not fully supported by Ninja)?

What technology with regards to this topic is supported by NT7? Can you send me on the appropiate documentation on how to use it?

Regards

mefTrader, NinjaTrader 6.5 already offered to access multiple bars objects (timeframes and instruments) in a so called MultiSeries strategy, the same concept has now been made available to indicators as well with our NinjaTrader 7 -

Great will study that ....

Is there a general section for NT7 with respect to DLLs?

[mefTrader]

When you add additional Bars for say 15min and 60min to your primary bars (say 5min) and Bars Back is set to 200 bars on the indicator is the 15min additional Bars in effect 200bars/3 or 200?

Unfortunately there's no DLL section - you could add DLL's as references in the NinjaScript editor (right click in the source code) and then use them programmatically.

The bars / days loading would be based on your primary chart series.

In the section "Accessing the Price Data in a Multi-Bars NinjaScript" if I have a user-defined data series say "Trend" can I access it as follows

Trend [0] - as per normal
Trend[1][0] - ??
Trend[2][0] - ??

[NinjaTrader_Bertrand]

mefTrader, this would be the added price data arrays only, if you want to access calcs done on added series either expose them or just access the plot that would be automatically exposed.

[mefTrader]

if Trend is a Plot as follows;

Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "Trend"));

Then does the above work?

[NinjaTrader_Bertrand]

Yes, this plot is then exposed per default and you could access it with MyIndicator(Parameters).Trend[0].

[mefTrader]

Okay so that I completely understand this

if my indicator has the following and is applied to say a 5min chart

protected override void Initialize()
{
Add(PeriodType.Minute, 15);
Add(PeriodType.Minute, 60);
}



protected override void OnBarUpdate()
{
if (BarsInProgress == 0)
{
Ov_Trend.Set(Trend[0]+Trend[1][0]+Trend[2][0]); // Overall Trend is the sum of 5min,15min, 60min
//Ov_Trend and Trend are defined as plots
}
}

[NinjaTrader_Bertrand]

mefTrader, more likely this since you need to point then to the BarsArray used -

Ov_Trend.Set(Trend[0]+Trend(BarsArray[1][0]+Trend[BarsArray2][0]);

[mefTrader]

Ok great - I will test it out!

This multi timeframes on the same chart - for multi times between different charts refer to
