The HSX bozos, who briefly experimented with a website “redesign”, have now reverted to their original platform.

Towards the end of October, I chronicled, in very harsh words, the so-called “redesign” of the Hollywood Stock Exchange website. I wrote that the HSX executives who gave the green light to that “redesign” are a bunch of usability bozos, who should be sent flipping burgers on Main Street, instead of running a prediction exchange.

My analysis was spot on —once again:

Today, I see that those smart a**es have reverted to the original Hollywood Stock Exchange website —as we knew it.

LATEST NEWS

- Rush to Memeorandum, the Drudge Report and Real Clear Politics to check what are the most talked about issues of the day.

- The (sad) death of Barack Obama’s grandmother has reminded the voters that the Democratic nominee is both “black” (African-American) and “white” (Caucasian). That might reassure some white voters, and could diminish a bit the so-called “Bradley Effect” —which I don’t believe is a factor in this presidential race, anyway.

- The 2 November surprises (Barack Obama’s aunt is an “illegal alien” + Barack Obama believes in the usefulness of very high green taxes) have probably damaged Barack Obama’s attractiveness with the voters who believe in strict immigration control and the virtues of free markets.

- The US stock markets have (probably, temporarily) stopped spiraling into the abyss. (John McCain became more unpopular each time the stocks went down, these last weeks. So, when Wall Street is doing OK, it won’t help Barack Obama, additionally.)

- Beware the exit polls, they have proved to be somewhat unreliable, in the past. They have a Democratic bias.

- As for how this historic day will roll out, check Nate Slver’s railroad at NewsWeek.

#1. Explainer On Prediction Markets

-

A prediction market is a market for a contract that yields payments based on the outcome of a partially uncertain future event, such as an election. A contract pays $100 only if candidate X wins the election, and $0 otherwise. When the market price of an X contract is $60, the prediction market believes that candidate X has a 60% chance of winning the election. The price of this event derivative represents the imputed perceived likelihood of the partially uncertain event (i.e., its aggregated expected probability). A 60% probability means that, in a series of events each with a 60% probability, the favored outcome is expected to occur 60 times out of 100, and the unfavored outcome is expected to occur 40 times out of 100.

Each prediction exchange organizes its own set of real-money and/or play-money markets, using either a CDA or a MSR mechanism —with or without an automated market maker.

Prediction markets enable us to attain collective intelligence. Prediction markets produce dynamic, objective probabilistic predictions on the outcomes of future events by aggregating disparate pieces of information that the traders bring when they agree on prices. The event derivative traders are informed by the primary indicators (i.e., the primary sources of information), like the polls, for instance. These informed speculators then execute their transactions based on their anticipations about the future —anticipations that will be either confirmed or infirmed.

The value of a set of prediction markets consists in the added accuracy that these prediction markets provide relative to the other forecasting mechanisms, times the value of accuracy in improved decisions, minus the cost of maintaining these prediction markets, relative to the cost of the other forecasting mechanisms. According to Robin Hanson, a highly accurate prediction market has little value if some other forecasting mechanism(s) can provide similar accuracy at a lower cost, or if very few substantial decisions are influenced by accurate forecasts on its topic.

The automated market maker of InTrade’s play-money prediction markets

Chris F. Masse November 4th, 2008

Michael Schmahl:

I think I have a guess as to how the play-money bot at Intrade works.

Here are the order books for today at 2:48AM (2008-10-27) for NTH.DAKOTA.DEM on intrade.com and play.intrade.com:

intrade.com play.intrade.com
BID ASK BID ASK
Qty Price Price Qty Qty Price Price Qty
1 34.1 36.8 5 101 34.1 36.6 14
3 34.0 37.5 6 103 34.0 36.8 105
50 31.1 38.0 33 6 32.7 37.0 49
3 31.0 41.5 5 150 31.1 37.5 106
25 30.6 42.0 50 103 31.0 37.9 49
8 30.0 44.0 2 125 30.6 38.0 133
20 26.0 44.9 15 108 30.0 40.1 100
50 20.0 47.0 20 50 20.0 40.9 101

It looks like each order of n contracts that gets placed on intrade.com is echoed by an order of 100+n contracts on play.intrade.com. This breaks down for very high or very low orders (there is no bid for 120@26.0, for example). I’m pretty sure that when these bids get canceled, their mirror-bids are also canceled.

I’m not sure what happens when someone takes a price, though. My guess is that the order is broken up into its separately-matched parts, and each part is mirrored in just the same way, which usually results in an automatic price-match at play.intrade.com. For example, if someone entered an order to sell 10@33.0, which would result in selling 1@34.1, 3@34.0 and the remaining 6@33.0, play.intrade.com would match 101@34.1, 103@34.0, and put 106@33.0 on the order book.

RELATED NOTE: As you have seen, Justin Wolfers at the Wall Street Journal has stopped promoting InTrade’s play-money prediction markets, and now links directly to InTrade’s real-money prediction markets.

Why would an event derivative trader inform his/her fellow traders about pieces of information that give clues about the future outcome of an event that they all bet on?

Chris F. Masse October 31st, 2008

- Why did Jenni Peterson give clues to her competitors?

- Why didn’t she keep the information (see comments #6 and #7) close to her chest instead?

- Do the traders who use play money are more talkative than the traders who use real money?

- Shouldn’t an event derivative trader beam out false signals instead of helping his/her competitors?

- Do trading induce solidarity, paradoxally?

At inception, I created an “Internet usability” category, and, since, I have published many Jakob Nielsen stories. Many wondered why I would bother. Now, the Midas Oracle readers can understand why.

How to break a successful prediction exchange in less than one week

Chris F. Masse October 27th, 2008

No Gravatar

Whiskey Kilo (a Hollywood Stock Exchange trader):

Change is one thing, breaking the whole site and acting like its nothing happened is another. The whole concept of trading movie stocks, movie bonds and options have taken a backseat to making sure you can blog, add friends, and “Schmooze”.

The old portfolio page was color coded and extremely easy to understand, you instantly knew if you were making H$ or losing your shirt. Now the current portfolio page is a small box, one colour, light grey on a white backround and the type is half the size of the font here, also you can only see 12 stocks at any given moment. Whoever OK’d this part of the site has to have never traded any shares online before.

From what I can gather, there was a beta version of this 3rd generation of the game, but no one paid any attention to the any of the feedback, two days after this new rollout, HSX.com started calling this new version a beta game, and what HSX staff there is say that portfolios are now their priority. However the only things that really work right now are the blogs, which pay H$10,000 a posting, adding friends pays traders H$1000, Online Polls, and Schmoozing. which paid initially H$1000, but now pays H$100 per reply. The only reason I see for paying traders to blog is to bring more eyeballs to the garish 728×90 and 300×225 ads on each page to pump the number of advertising views on HSX. But if this is part of the grand scheme here, I can’t see Gold coin or Forex advertisers closing sales from a bunch of 13 years because all the veteran traders have left in disgust.

I welcome Jed [*] to read the HSX Support page: http://www.hsx.com/cms/forums/support and look around, I shudder to think this all is going to be a B-School case study on how to kill a successful site in under a week.

[*] Jed Christiansen, who put up a comment in defense of HSX (Jed systematically defends the people I slam on Midas Oracle) —and who has just begun an MBA education.

The new Hollywood Stock Exchange website (recently redesigned) sucks as much as an indigestible fruit cake.

HSX-sucks.com — I predict that somebody will soon register this domain name.

Many HSX event derivative traders have complained to me privately about the website redesign: they hate it more than they hate the recent financial bailout. One HSX trader went off on the Prediction Markets group discussion area at LinkedIn. Today, another HSX trader is writing a long prosecution of the HSX website redesign. Read it in all, and spot the many comments at the bottom, from fellow HSX traders.

The root of the problem is Alex Costakis —the director of HSX. My assessment of him is that he doesn’t get the Web. He is as clueless as a maggot trying to play Jazz. He is not an open person, and the Web is all about openness. This guy is a drag on HSX. I predict he will lead to HSX’s death.

The only 2 persons that could lead to a revival of HSX are Max Keiser or Nigel Eccles. Let’s hope that Cantor Fitzgerald will call them for help.

UPDATE: See the comments.
