New IE Singapore symbols

The following symbols have been created for IE Singapore weekly import, export, domestic export and re-export values (in Singapore dollars) carrying 0 decimal place and volumes (in metric tons) carrying 4 decimal places in dispatch categories IO (petroleum) and IP (petrochemicals). They reflect new trade activities within the past week. The values for these new symbols will be backfilled next week. The key trade statistics for oil appear on PGA pages 1300-1338 and the key trade statistics for petrochemicals on PCA pages 800-806.
