How is previous settlement (Pstl) calculated?

Previous settlement (Pstl) refers to the settlement (Stl) published by the exchange for the previous trading day for a specific product.

The exchanges calculate a settlement price at the end of each trading day for each product. How precisely the settlement is calculated varies depending on the exchange that provides the data.

Previous close (PClose) refers to the price of the last trade on the previous trading day for a specific product. For data published by brokers, PClose is used instead of Pstl due to the brokers not publishing settlement prices.
