The Market Data delivery schedules is indicated on page 6 of the Market Data User Guide.
Note: Although Platts makes every effort to provide value updates at consistent times, we cannot and do not guarantee the market data cut in which any given value will be delivered to subscribers. Our goal in each cut is to deliver as many values to subscribers as early as possible.
