ES #F wrong Prev value

[gem2004]

Just now as it can be seen in the attached image the Previous close for ES is given as 1094.60 but ES only trades in quarter point ticks.

The same error was observed during premarket and the early hours of regular trading hours and has also been noticed a few times this month.

Thank you for your attention to above.

Changes made in the feed at the Exchange has caused small discrepancy seen between the settlement price in the Time & Sales and the one posted in quote and chart windows (1145.25 vs 1145.20 today) is due to how the CME handles their settlements.

This message is posted on the CME Website

Settlement prices for the E-mini S&P 500 and the E-mini S&P Midcap 400 may differ slightly from the "true" settlement price displayed on CME's Daily Bulletin. These slight variances in settlements are the result of rounding due to differences in the minimum tick sizes between the E-mini contracts and the full-sized contracts. Additionally, the settlement price displayed on the Daily Bulletin matches that of the full-sized contracts for purposes of marking-to-market, as the contracts are fungible, on a 5:1 basis.
Example: E-mini S&P 500 futures contracts are traded in .25 increments and the full-sized S&P 500 contracts in .10 increments.

The CME has planned fix which will be implemented on Feb 6, 2010.
