Singapore: How frequently should a reporting entity update the valuation fields?

The valuation fields should be updated as and when the valuation of a derivatives contract  is updated. Reporting entities should take guidance from the Guidelines on Risk  Management Practices – Market Risk in formulating their valuation policies, including  how frequently valuations should be updated to reflect the mark-to-market/model  value. Where valuation of a contract is conducted multiple times within the same day, the  reporting entity could choose to update the valuation fields for the contract once using  the latest valuation changes for that day.
