Complex processing of DataSeries

[sktrader1]

I have debugged it and now the data are in a dataseries. The question is how do you plot the dataseries.

Hi sktrader1,

Please refer to this sample...

Just go to tools>edit > indicator and look at just about any indictor code. For example SMA, which is simple. In almost every case you will see a

.Set(myValue[0])

..method...where myValue is your data series.

Hi mountainclimber,

Unfortunately, plotting from a strategy does not work in the same way as an indicator.

Thanks NinjaTrader that could be useful. Sorry just starting with the software and need to know how things are linked together. If you have more samples for generating the plots during the backtesting too it would be great. mountainclimber I am trying to do something slightly more difficult but eventually I might go backwards and use the primary loop that is in effect the OnBarUpdate if I can - that will utilise this method.

[NinjaTrader_Tim]

You can also add plots in a strategy, called from an existing indicator. Something like...

protected override void Initialize()
{
            
   Add(Stochastics(7, 14, 3));

}

Oh, didn't realize he was in a strategy...my bad.

Hi NinjaTrader, went through the sample code thanks. Is the reason that this will not work on historical data be that there is not OnBarUpdate event activated?
Thanks

Currently on the previous example I am plotting my output using the following:


for(Bar=0;Bar<=Bn;Bar++)
{
T=Bar.ToString()+"TT";
DrawDot(T, false, Bar, Result[Bar], Color.Green);
}

Where Bn is the Min. Bars required (see below)
T plays the role of the unique reference. Works fine. Is that a good accepted solution? Of course this calculates for the last Bn and therefore as there are new bars the old ones are removed from the chart.

Hi sktrader1,

This should work on historical, are you seeing any errors in the Log tab when you apply it to a chart?

[sktrader1]

Sounds good then. No errors. Is there a guide for a bit more advanced examples around?

Hi sktrader1,

Of the plotting from a strategy? Not that I am aware of, but searching these forums will likely bring up other discussions or even examples on the subject.
