Parameter Error

[dukeb]

The following code causes the attached error when I load the strategy on a chart. However, the stategy seems to work fine.
When I load it on the strategy analyzer, no error occurs.

I have tried to enter parameters with objHighBarsAgoNumber (which is what the error seem to be about) but I can't get it to compile. The strategy is doing what it should. I would like some insight on what the error is happening.


objHighBarsAgoNumber.Set (Highs[0][1]);
//
HighBarsAgoNumber = (HighestBar(objHighBarsAgoNumber,30)+1);

Thank you,
Duke

Can you post the code you're using in #region Properties?

Sorry Duke - I meant the #region Properties section which is below OnBarUpdate()

Although - do you mean to expose this data series as public? You might just wanna try changing it to private DataSeries in your Variables section

Pleaes have a look at our DataSeries class of our Help Guide for information on how to declare and set a data series:

Sorry, Matthew.. my fault,
#region Properties
[Description("")]
[GridCategory("Parameters")]
public int MyInput0
{
get { return myInput0; }
set { myInput0 = Math.Max(1, value); }
}

#endregion

Thanks - in Variables can you please set thees data series as private:

private DataSeries objHighBarsAgoNumber;
private DataSeries objLowBarsAgoNumber;

Matthew,
That fixed it. Can you explain the problem?
Thank you very much..

A public variable needs to be serialized which can then be used as a public property.

Since you're not exposing this data series outside of this script, there is no need to serialize this data series and you can simply declare it as private.

If you wanted to expose this data series to another indicator or strategy, you can link the private DataSeries to a Public DataSeries which would then be serialized in the #region Properties section.

If you'd like to learn more about this, please see our Help Guide article on Exposing indicator values which are not plots:
