Integer Output

[Faspomy]

I have an indicator which needs to output an integer to strategies.


I tried an IntSeries, but am having errors with the following property;

[Browsable(false)]
[XmlIgnore()]
public IntSeries GridValue
{
get { return gridValue[1]; }// error here
}


EDIT: I am receiving an error which states 'Cannot implicitly convert int to NinjaTrader.Data.IntSeries'.


How else can I output an integer value from an indicator without it being 'set' as above, so its value may be used within Strategies ??

I suspect 'gridValue' is in fact your IntSeries? If yes, then:

return gridValue;

is sufficient. If you want to return the actual integer value and not the series, then change to:

public int GridValue

Thank you Ray.


I'm not sure what you mean by " If you want to return the actual integer value and not the series, then change to: public int GridValue"

Will a series allow me to read integer values set by the indicator ? For example;

if (SMA(14).Value[0] > SMA(14).Value[1])
            {
                gridValue.Set(20);
            } 

I would like to access the '20' in a strategy.

When I create a public int, the value is browsable, and is pre-set within the indicator's properties. Example; MyIndicator(GridValue, period)

How can I gain access to GridValue's output from the indicator, without having its value pre-set as above ?

gridValue is a series of values, an array for arguments sake. If you want to expose the entire array, then

return gridValue;

if you only want to return the current bar value held by the gridValue series, then

public int GridValue

Thank you Ray.
I changed to an integer

 [Browsable(false)]  
        [XmlIgnore()]        
        public int GridValue
        {
            get {return gridValue; } 

Still having a problem accessing the data, though. Here are conditions within the indicator to set gridValue;

             SMA1.Set(SMA(14).Value[0]);
            SMA2.Set(SMA(7).Value[0]);
            
             if (CrossAbove(SMA(14).Value,SMA(7).Value, 1));
            {
                gridValue = 10;
                Print("gridValue = 10");

            }
            
            if (CrossAbove(SMA(7).Value,SMA(14).Value, 1));
            {
                gridValue = 20;
                Print("gridValue = 20");
            } 

This is the Strategy code to read the value;

           if (MyIndicator(1).GridValue == 10)
            {
                EnterLong(1, "");
            }
            
            if (MyIndicator(1).GridValue == 20)
            {
                ExitLong();
            } 

What should happen is obvious. However, nothing happens-- no buys or sells are activated.

Also, I am receiving "gridValue = 10" & " gridValue = 20" printing-out to the output window, at the same time, on every bar.

Questions;
- am I formatting the integer correctly in the indicator ?
- do conditionals work differently in an indicator versus a strategy ? If not, why would I be receiving erroneous results ?

Hello,

This link has a reference sample that shows how to make a variable exposed:

Notice what is going on in the Properties area and how Update() is used.

Ban,

thank you. That should solve the update problem.

I am still having a problem, though, with the values being printed-out to the output window as both '20' and '10' on each bar.

Am I missing something ?

Hello,


Try removing the ";" after each condition and see if it works better.

Also you do not need to use SMA(14).Value and SMA(7).Value. Do it this way:

if (CrossAbove(SMA(14), SMA(7), 1))
{
gridValue = 10;
Print(“gridValue = 10”);
}
