Platts reflects the daily PX derivatives value based on trades, bids, offers and indications of tradeable value reported to S&P Global Platts editor.

Platts uses a Market-on-Close (MOC) assessment methodology which is a day-long process that ends at 4:30pm Singapore time—the timestamp for Platts Asia PX derivatives assessments.

The S&P Global Platts Market on Close for paraxylene CFR Taiwan/China derivatives is a structured price assessment process that is designed to ensure the highest quality of market data for use by Platts reporters when assessing the tradable value of PX CFR Taiwan/China derivatives at 4:30 pm Singapore time.

In the derivatives MOC, Platts publishes firm bids, firm offers and trades reported for publication transparently by market participants. The Platts MOC ends at 4:30 pm Singapore time, but the process itself runs all day, with clear guidelines around the submission of bids and offers for publication, changes to price, and deal reporting.

Throughout the trading day, Platts editors survey participants in the PX market, seeking information on any bids, offers, trades conducted in the spot market, in addition to information that may impact derivative market fundamentals. Platts also gathers and publishes information received from market participants that report their own firm, named bids, offers and trades for publication.
