strategy parameters

[mballagan]

I would like to restrict the values of a parameter of a strategy to a few distinct values say 1, 2, 4, 6

In the set method for the parameter should I do something like the following?

set{
if (value==1 || value==2 || value ==4 || value==6)
{
myparameter = value;
}
else
{

throw new Exception("Inavlid parameter");
}
}

mballagan,

No. That just means users typing in other values will have problems. Instead you should just do it in your OnBarUpdate where if the variable is 2 you do something, if it is 4 you do something else, but if it is 3 it just does nothing.

Thanks but the problem with that is that the user has no message indicating that they have entered an invalid parameter.

Right. What you want is not supported, but you can try your idea. If it is a int parameter it will be able to take on all values unless you generate some logic that resets it to some default value that is allowed.
