Elasticia Production System upgrade - "Official day closing price enhancement release"
Publiceringsdatum: Dec 09, 2013 3:55:45 PM
Elasticia Production System is planned to be upgraded with the "Official day closing price enhancement release".
The upgrade will be performed in three steps, starting on Monday, December 16 and completed on Friday, March 14, 2013:
Step 0. December 16, 2013. Internal system changes. No action required.
A short "glitch" in system availability will be noticeable while we upgrade the internal system.
Step 1. December 18, 2013. Business changes. No action required.
The official day closing price will be set to the theoretical closing price for instruments on the NDX market segments where active market making takes place. The official day closing price is disseminated on the public channel (market data statistics).
The new Closing Price MarketMakerQuote-flag *will not* be used.
The traditional official day closing price for the affected instruments will be available as Last Price in the market data statistics.
Step 2. March 17, 2014. Technical changes. Action required to ensure that your systems support the dissemination of the MarketMakerQuote-flag for closing price.
The new Closing Price MarketMakerQuote-flag *will* be used.
The release has been thoroughly tested, but we would now like to invite you to take part in the public testing of the release to help us ensure the quality and give you an opportunity to to test your integration.
New functionality introduced for NDX instruments. Allows the official day closing price (part of the market data statistics disseminated on the public channel) to be set on other criteria than, as of today, being based on the actual trades having been performed. This new feature makes it possible for a market maker to provide a theoretical closing price after the market has been closed.
