Can I have different parameter for different instruments?

[cassb]

Is there a way to set up a strategy so that the user parameters would be different depending on which instrument the strategy was trading? Let's say I want the YM to trade 5 contracts, but the ER2 to trade only 4. If I have a "Contracts" parameter for the strategy, how do I get it to change based on the instrument.

And I already tried setting up some logic in the Initialization tag to check the instrument name and change the "Contracts" variable in the code to what I want. But that didn't seem to work -- it used the default value of the parameter anyway. Maybe the Properties are set after Initialization is called?? In that case, could I set the value there instead?

Thanks!

You would need to internally code it by checking the instrument and then setting some internal variable that represents the trade size. Then pass this variable into any order method.

I did that, but it didn't work. I guess then I coded it wrong. I'll try again, thanks Ray!

I mean internal in that you do not expose this as a parameter in a dialog window. Its likely that the parameter values are displayed before Initialize() is called etc...

Oh, I see what you mean. Yeah, OK... I can do that. I wanted to be able to change the value easily as a parameter, but maybe that's not the best method for something like this. I guess parameters override internal values even in the Init tag.
