Reset() Question

[Zeos6]

HI,

I am having an issue with the Reset() method. I have the following code:

In Initialize():
Add(new Plot(Color.Cyan, PlotStyle.Dot, "TDown"));
Add(new Plot(Color.Blue, PlotStyle.Dot, "TUp"));
Plots[0].Pen = new Pen(Color.Cyan, 6);
Plots[1].Pen = new Pen(Color.Red, 6);

In OnBarUpdate():
if(CurrentBar < 10)
{
TDown.Reset(); // sets null value for plotting purposes but 0 value for mathematical purposes
TUp.Reset();
...
}

When I print values of TDown[0] or TUp[0] I get actual price values - the Close value of the bar. I expected to see null, or zero values or NaN. I must be using Reset() incorrectly because my output does not agree with the documentation. Any suggestions?

Thank you for any help you may be able to provide.

The point may be moot, as that code seems to indicate that you are pretty much otherwise doing nothing if (CurrentBar < 10), at which point, as you have done nothing, I believe Plots are, bu default, set to the Close value for the bar, but not plotted.

You can always force the value to zero, before you reset, thus:

TDown.Set(0);
TDown.Reset();

You might want to check if those values are even a valid plot. ref: http://www.ninjatrader.com/support/h...dataseries.htm

Hi Koganam,

Thanks for your reply. I was actually wondering about that over the weekend. It appears that you actually need to set a value before you can reset it - even though a default value is already in place. Seems odd since a default value of bar close already exists there but I will give it a go.

On another note, the code snippet with CurrentBar < 10 is contrived and artificial. I simply wanted to check what values were being reset in the plot.
