I have US data, but I get a message about SPX when charting or running an exploration.

The message received is, “Error in column A: Error retrieving data for Security() function. No error Symbol: .SPX”. First try bringing up the chart for .SPX. If you do not get data, it will need to be added to your subscription with Metastock. Please contact Metastock & they can assist you in adding the exchange needed for SPX.
