Basing one Property/Parameter on Another Property/Parameter

[TheTradingMantis]

I am trying to modifiy the set{} statement for one parameter so the parameter can only be less than another parameter. A problem occurs when set is called for RSILengthLong; it is getting the prior value of rSILengthLong and not the value just entered. If I enter the value a second time, it works. I think I understand why this happens, but cannot figure out code that will allow it to function correctly the first time I enter a new value. The code I'm using is:

[Description("Momentum Length (Long) - Value between 5 and 50")]
[GridCategory("\t\t\tEntry")]
[Gui.Design.DisplayName("\t\t\t\tMomentum Length (Long)")]
public int MOMLengthLong
{
  get { return mOMLengthLong; }
  set { mOMLengthLong = Math.Min(Math.Max(5,value),50); }
}
 
[Description("RSI Length (Long) - Value between 2 and 50")]
[GridCategory("\t\t\tEntry")]
[Gui.Design.DisplayName("\t\t\t\tRSI Length (Long)")]
public int RSILengthLong
{
  get
  {
     int returnValue = 0;
     if (rSILengthLong > MOMLengthLong)
      {
        returnValue = MOMLengthLong;
      }
    else
    {
      returnValue = rSILengthLong; 
    }
    return returnValue;
  }
  set
  {
    Print(rSILengthLong+" "+MOMLengthLong);
    if (rSILengthLong >= MOMLengthLong)
    {
      rSILengthLong = MOMLengthLong-1;
    }
    else
    {
      rSILengthLong = Math.Min(Math.Max(2,value),50);
    }
  }
} 

If anyone has a suggestion, it will be greatly appreciated.

Thanks,

Greg, this probably has to do with the variable you are accessing. When making a variable public (editable), there are actually two variables, the private variable (with lowercase starting letter) and the public variable (capitalized starting letter). Please try comparing the public variables and see if that does the trick.

Hi Austin, I tried using the public variable RSILengthLong, but I get a recursion error.

Greg, I just checked with a co-worker and this actually isn't possible. You can run the check in OnStartUp() and modify the variable on the fly to the value you want. If you are using NT6.5, OnStartUp() doesn't exist, but you run it in this little block of code:

OnBarUpdate()
{
    if (CurrentBar == 0) // indicating the very start of the indicator run
    {
        // change your variables
    }
}

Try
[RefreshProperites(RefreshProperties.All)]

On the first property

Baruch, Does that work in NT7? I added the lines but get an error that the namespace RefreshProperites does not exist.

Austin, that will work as a fallback.

Thanks guys!
