Volatility Guard

 * – ( View AfD View log  Stats )

Prod deleted by page author with no reason provided. Still isn't WP:NOTABLE and still is WP:ADVERTISING. Tigraan (talk) 17:23, 17 December 2014 (UTC)
 * Delete Fails WP:PRODUCT. A feature to prevent issues in trading no longer used by nasdaq.  At most, it is worth a sentence in NASDAQ, maybe.   While notability is not temporary, I don't seen anything much about this historically other than it being announced and then it being removed.  Trysha (talk) 18:46, 17 December 2014 (UTC)
 * Delete for me as well, of course.Tigraan (talk) 10:02, 19 December 2014 (UTC)

Another perspective: History books that will mention the various market crashes due to algorithmic trading. Invariably it will mention trading limits (vanilla price checks which Do Not Help to prevent price Volatility related crashes e.g. a price may stay within a 'tolerable' range while its volatility is about to cause a crash). By removing the concept of Volatility Guard from human memory (i.e. no one explains what it does and how it was used), it essentially removes one of the few, if not only, named protection/ products/ concepts against a specific type of trading limit that is Designed against exotic trading products (that bet on volatility, all the rage of these two decades). — Preceding unsigned comment added by Writer09 2014 (talk • contribs) 00:20, 18 December 2014 (UTC)

@Trigraan, Prod was deleted with reason, possibly unsatisfactory to you, put on the Talk: Volatility Guard Prior to deletion. Hope the above perspective is better and also, in the correct location for discussion. — Preceding unsigned comment added by Writer09 2014 (talk • contribs) 00:23, 18 December 2014 (UTC)


 * I have no problem with ProD being removed - you do not need to provide reason to remove it. Nonetheless it would be better to provide that reason, otherwise the article just survives one more week before being killed by AfD for the exact same reasons that made me put the Prod tag.Tigraan (talk) 10:02, 19 December 2014 (UTC)

@Trysha, volatility guard as a concept, is not used in American markets. I'm not sure how America-centric Wikipedia is meant to be; Volatility Guard (concept) is still used in Nordic markets at the time of this message to you. http://globenewswire.com/news-release/2014/11/26/686613/0/en/IT-INET-REMINDER-Production-launch-of-safeguards-in-opening-and-closing-auctions-on-the-Nasdaq-Nordic-and-Nasdaq-Baltic-exchanges-106-14.html?print=1 Thank you. — Preceding unsigned comment added by Writer09 2014 (talk • contribs) 00:30, 18 December 2014 (UTC)

@Trysha and Trigraan: This is a good article to have on wiki. Volatility Guards are a fact and they are STILL USED and APPLIED. Many people are still unaware of the mechanism. There is a lot of work around Volatility Guards now. On 01 December 2014, Nasdaq Nordic and Nasdaq Baltic introduce auction safeguards to be applied to those shares and ETFs/ Fund Units on below markets, including respective First North markets, which also have volatility guards during continuous trading.

If we have articles related to the concept of "Volatility" in Wikipedia, It is very natural to have an article explaining the concept of Volatility Guard.

General public should be made aware of this. Next time we will have a significant volatility spike in one of these markets, the volatility guards will be triggered leaving a lot of investors completely clueless.

Here is how it is currently used in the safeguards in the NASDAQ OMX Nordic:

http://www.globenewswire.com/news-release/2014/08/28/661951/0/en/IT-INET-Introduction-of-trading-safeguards-to-opening-and-closing-auctions-in-NASDAQ-OMX-Nordic-and-Baltic-exchanges-80-14.html?print=1 Quoting from http://www.globenewswire.com/news-release/2014/08/28/661951/0/en/IT-INET-Introduction-of-trading-safeguards-to-opening-and-closing-auctions-in-NASDAQ-OMX-Nordic-and-Baltic-exchanges-80-14.html?print=1

" The dynamic volatility guards* used in continuous trading are the basis for the percentages used as safeguards in the opening and closing auctions:

in the opening auction the safeguards are two (2) times the dynamic volatility guards and in the closing auction the safeguards are the same as dynamic volatility guards.

Dynamic volatility guards are set on order book level and disseminated as reference data via the Genium Consolidated Feed and Nordic Workstation. See the percentages normally used as trading safeguards in the opening and closing auction in the table below. NASDAQ OMX Nordic holds the right to apply deviating percentages on individual order book."

I will be very happy to add more technical explanations on how this works. — Preceding unsigned comment added by 103.246.92.54 (talk) 06:06, 18 December 2014 (UTC)


 * "globenewswire.com" is Nasdaq-operated, from the looks of their homepage. Please consult WP:PS, which includes "Do not base an entire article on primary sources, and be cautious about basing large passages on them" - that's pretty much what is going on right now.
 * If you can provide a secondary source for natability, I would withdraw my support for deletion. The article would still have issues but those would call for a rewrite, not a deletion.Tigraan (talk) 10:02, 19 December 2014 (UTC)

@Tigraan: Volatility Guard is significant enough to get the attention of the World Federation of Exchanges. http://www.world-exchanges.org/news-views/nasdaq-omx-nordic-introduces-updated-volatility-guards-protect-investors-and-listed World Federation of Exchanges is a neutral, international entity that monitors 64 markets/ exchanges for their most significant and notable developments.

It has also been mentioned in multiple publications and news sources such as:http://www.reuters.com/article/2010/06/02/nasdaq-circuitbreaker-idUSN0218608620100602  with comments from NYSE spokesman, the chief executive of BATS Global Markets and other Finance firms. Other news website such as WSJ give updates on market participants reactions :http://www.wsj.com/news/articles/SB10001424052748703509404575300641791256802?mod=_newsreel_5.


 * The Reuters source looks great. Could you edit the article to include it? It might still fail under WP:PRODUCT as Trysha mentioned, but at least that's something concrete to go about. Tigraan (talk) 17:07, 22 December 2014 (UTC)

@Tigraan: The Reuters source has been included as you suggested. I agree that the reuters source looks great and gives a clearer idea about the context now. — Preceding unsigned comment added by 183.90.37.93 (talk) 14:30, 26 December 2014 (UTC)
