New IE Singapore symbols

The following symbols have been created for IE Singapore weekly import, export, domestic export and re-export values (in whole Singapore dollars) and volumes (in metric tons to 4 decimal places) in Market Data categories IO (petroleum). They reflect new trade activities within the past week. The values for these new symbols will be backfilled next week. Key trade statistics appear on PGA pages 1300-1338 for oil and PCA pages 800-806 for petrochemicals.
