Correct Use of Print Statements

[zeller4]

Hello,

I'm using various print statements to check orderstates in my custom strategy using Unmanaged = true.

I continue to get error messages:specifically "Object reference not set to an instance of an object".

Is this a valid print statement?

Print("longOrder.OrderState:\t"+longOrder.OrderState);

In other words, will this create the error message?

Or do I first need to check for null?

if (longOrder != null) Print("longOrder.OrderState:\t"+longOrder.OrderState);

I believe it has to do with a null reference not being checked but not sure where to look next. If it's more than just checking for null at the print statements, I'll post the code.

Thanks,
Kirk

Kirk, correct you should add a != null check before attempting to access the IOrder objects in your prints.
