Colin,
Switch the GS to offline then change the symbol in your GS the day
before it changes in the market. Many feeds will accept the change
and the new data comes in.
If you have DTN satellite then switch the GS to offline then change
the symbol to the new one and export all the data. Then delete the
symbol and add the new one. Then import the old data.
Did I understand the question?
Best regards,
Jimmy Snowden
