    As you can see I'm trying to to get the indicator to know which Chart it's on so it knows which FUTURES contract to use. I typed Conditional statements in the void Initialize() area, I don't know if that causes problems.

    Can someone please help fix this error.
    Contract "6J 06-14" comes into existence on a specific date. Before that date, as the contact does not exist, your second price DataSeries will not be created, so any reference to it will be out of the bounds of any array that references it.

    You will have to make some kind of arrangement to make sure that you are referencing existing contracts. One way might be to reverse your logic, and run on the 6J contract, calling $USDJPY, as the latter is an invariant string. Other ways would be more complex, as you would have to determine the date, so that you can use the correct contract.
