Exposing indicator values that are not plots AND NOT DATASERIES

[xTrader1]

Hi ,

I saw an example in

http://www.ninjatrader-support2.com/vb/showthread.php?t=4991

Regarding NT 6.5 :

Because of memory considerations I want to avoid creation of additional data series and I want to expose certain indicator value as a property.
My code is like:

Indicator A:

protected override void OnBarUpdate()
{
.............
state1 = [certain value]
..........
}

Read only property:
public int IPos
{
// read only - for external usage.
get { return state1 ; }
}


Indicator B (or strategy B )
val1 = IndicatorA(2,10).IPos ;

There are no compilation errors, but val1 is always 0 , despite the "state1" has different values for different bars.

I would expect that this statement will return current value of the property for every OnBarUpdate called.

I suspect my problem has something to do with a way my strategy calls OnBarUpdate().

What's wrong ?

xTrader, if you haven't taken a look at the indicator potion of the sample titled exposing indicator values please do so.

The code for the publically exposed variable needs to have a section that "updates" the value, like so:

public double ExposedVariable
{
     // We need to call the Update() method to ensure our exposed variable is up-to-date.
     get { Update(); return exposedVariable; }
}

So for your situation, try this and see if it works:

public int IPos
{
    // read only - for external usage.
    get { Update(); return state1; }
}

Sorry , I overlooked.

It appears not only in the example, but also in the help file.

Now it works. Thanks.
