    Please help with this error message

    Hi,

    I'm getting this message "Error on calling the 'OnBarUpdate' method for indicator 'myTDSetup' on bar 26: Key cannot be null. Parameter name: key"

    What does this mean? What is "key" referring to?

    Kay, most likely you try accessing an empty object at this point in your code - you'll need to debug it to determine if and when this is the case.
