Current Contract

[BradB]

I notice that when I add an instrument to my Instrument List via the Instrument Manager, it always adds the current contract. Is there a way I can test for the current contract of a futures instrument from an indicator?

Hi Brad, this is unfortunately not possible as the rollover dates could not be accessed programmatically.

Would you have any suggestiions then as to how I test the validity of a contract then? I have parameters which allow a user to specify the instrument and contract to be added to an indicator. If they type in an invalid contract the indi dies with a divide by zero error. I'm trying find a way to either test the parameter for a valid contract and/or capture the error so I can display an appropriate message to the user.

Hello,

No way to test the validity of the contract that I can think off.

About the only thing you can do is trap the error with c# using try() {} catch() {} blocks.

More information on using try catch blocks if your not familiur with them can be gound online.

Let me know if I can be of further assistance.

Thanks Brett...but I have tried using try/catch and they don't seem to work during initialization where the ADD takes place.

Can you give me an example of an incorrect entry for the parameter of Add() for the instrument that would cause the divide/0 error.

Also, do you have anything else in Initialize() other then the adds, if so please post them.

I look forward to assisting you further.
