[edit] TWAP, VWAP → Moving average (finance)

I'm not sure that a pure merge of these three is the right answer. However, it looks like the TWAP & VWAP articles overlap the Weighted moving average & Other weightings sections of this article. They should probably either be consolidated or, if separate articles makes sense, de-duped and cross-referenced. -- JLaTondre 01:21, 29 June 2006 (UTC)

Yes, the other weightings has a bit, but I think the actual WMA section is not related to VWAP (not sure exactly what TWAP is supposed to be though.

I'm planning to expand double-exponential moving average mentioned and add a related bit on EMA of EMA. For that I was considering unmerging in fact, ie. split the sections into separate articles. They seem substantial enough topics to get a page each. -- Kevin Ryde 01:39, 29 June 2006 (UTC)

I phrased my comment poorly. I meant TWAP & Weighted moving average and VWAP & Other weightings respectively. I am basing my interpretation of the articles only, but it seems like this article addresses the math and TWAP & VWAP address specific computations that use this math. -- JLaTondre 14:52, 29 June 2006 (UTC)

There is no reason whatsoever to merge them. Moving averages are not directly related to TWAP and VWAP at all. es:leomty july 20, 2006

There's a lot of information about how VWAP/TWAP are actually used that is very specific to the order mechanisms used in stock trading. The text for both articles includes some of this information already, and those aren't even close to complete coverage yet. Were you to merge them into the Moving Average page based on the similarities in computation, eventually they'd need to get split back into separate articles anyway to hold all those details.

What would make more sense is to create a page devoted to how large volume stock market orders are handled that includes the current text in VWAP/TWAP, and can get expanded from there. Other topics to include would be things like how large firms broadcast and execute large volume block trades with each other (see http://thomson.finance.lycos.com/lycos/iwatch/help/iw_advantages.htm for a good intro to that subject). I would suggest naming the new page "Institutional Trading", with subsections for Interest messages/Super messages, VWAP, and TWAP. --GregorySmith 08:03, 22 July 2006 (UTC)

[edit] This isn't a finance-specific concept

The moving average was introduced in 1870 by Woolhouse a way of smoothing actuarial mortality tables, and is one of the wider class of nonparametric regression / smoothing methods. In particular there is a general class of methods, called local polynomial kernel regression, in which we fit a polynomial to nearby data points, with the points selected and weighted according to some function of their distance from the point in question (the selection/weighting function is called the "kernel"). The moving average is the special case where the polynomial is of degree 0 and the kernel is a step function (uniform within the cutoff range, 0 outside it). The weighted moving average is of course another special case where the polynomial is of degree 0 and there is some non-uniform kernel (that case is also called Nadaraya-Watson regression).

I'd propose that this be moved to a location such as moving average (statistics), where the concept is discussed generally. Its use in finance should be mentioned, but is just a straightforward application; people can and do just as easily smooth all sorts of other time-series and non-time-series data, like daily temperatures, medical data, and mortality tables as mentioned above. --Delirium 05:11, 2 August 2006 (UTC)

I agree, it seems better to make applications of moving aveages in a financial setting topically subordinate. --HappyCamper 05:13, 2 August 2006 (UTC)

Neither is suitable: Moving average (in this article) is neither a financial nor statistics term. It is an indicator (trend-type) for technical analysis. According to the naming conventions in category:technical analysis, it should be named moving average (if no conflicts) or moving average (technical analysis) (if conflicts occur). Since there's a conflict, we should move to moving average (technical analysis). --Wai Wai (talk) 05:21, 4 August 2006 (UTC)

That doesn't make any sense to me. It's a statistics term; a type of local smoothing (local regression, locally weighted regression, etc; there are a million names for it). Its use in technical analysis is one particular application to the domain of financial time-series data, but hardly a canonical one. Moving averages, even restricting ourselves to time-series data, are also used in, for example, baseball statistics, weather statistics, etc. --Delirium 06:59, 4 August 2006 (UTC)

This term alone can be a statistic term, but you forget to take the context into account. Since this article talks about moving average in technical analysis (see the category tag and the first statement), the term is definitely not meant to be statistic in this particular article. Please go to here and read that article. Note how this article is categorized (ie Technical Indicators and Overlays > Moving Averages). Also read the chart. You will know what moving average means in stock market or technical analysis.

If you are looking for other uses of moving average, you are reading in the wrong place. You should go to here instead.

In conclusion, it should be moved to moving average (technical analysis). --Wai Wai (talk) 07:44, 4 August 2006 (UTC)

In that case, this article should be made specifically about the application and its use in technical analysis---why it's used, who uses it, etc., etc., and link to another article for the definition, the equations, etc., since those aren't anything specifically to do with technical analysis. --Delirium 07:50, 4 August 2006 (UTC)

Yes, you are right. This article is not informative. It doesn't say much about its application on the market. However there're links at the bottom which will give you more information than this article (oh poor!). It should be worked on after the article is moved. --Wai Wai (talk) 08:43, 4 August 2006 (UTC)

Since no one opposes it, I'm going to move the page. Best regards. --Wai Wai (talk) 06:48, 7 August 2006 (UTC)

I've deleted the cut-n-paste "move" & did a proper move. -- JLaTondre 12:54, 7 August 2006 (UTC)

[edit] VWAP is stand-alone term

I believe strongly that VWAP should remain as a separate page and not be merged with this page. VWAP is very widely used as the standard benchmark for execution performance in equity trading. Conflating the two would be misleading. Ronnotel 16:57, 11 October 2006 (UTC)
