Does anyone notice that the buy and sell prices for Yes automatically match themselves up to the sell and buy prices of the No shares? Whenever I make a trade or an open offer, the corresponding opposite numbers adjust themselves accordingly, minus 100.

Does someone have an automatic trading script running that monitors this page and inputs or removes open offers immediately, with the idea that someone deciding to trade one side is an indicator to follow?

Yeah we finally have a healthy AM-radio population as well. Check out the comments in the debt ceiling market if you want to know who's money you were taking. Unfortunately I feel like long-term those sorts of people are going to disappear on their own because it's one thing to ignore being wrong about something it's entirely another when being consistently wrong is also costing you money.

Vox Nihili got into an argument with one of them because he thought that he owed the governement $828,816. The good news for PredictIt users is the pool of AM talk radio population is huge. The bad news for the country is that the pool of AM talk radio population is huge.

I stupidly bought a bunch of LAGOV Dem NO shares at 54¢, now it's in the 30s and I'm stuck hoping that Vitter's outlook improves. Last poll has him down by 12, but its a Dem-sponsored poll.

I don't know Louisiana that well, but how much can an 8-year-old sex scandal matter if it didn't stop him from getting reelected last time?

I doubt they'll go away. There's bunch of literature on how consistently conservative media consumers fall for ideological affinity fraud (Tea Party pacs that just keep the donations, fake investments in Israeli oil futures, overpriced gold to hedge against Obama destroying the dollar, etc). This is a demographic with money to burn and an entire industry has been built around getting them to pay for scams that confirm their biases.

I'm guessing they'll keep showing up in the markets that conservative media tends to talk most about (presidential race, shutdowns, whether Hillary will be charged with a felony, high profile SCOTUS decisions on "culture war" issues, etc).


EDIT: Someone should convince PredictIt to start having markets on how much health care premiums will rise and whether there will be hyperinflation by year's end. You could make a killing whenever Limbaugh or Glenn Beck mentions them.

If you buy no across multiple markets you should only be charged based on your risk instead of the value of the shares. Being the first linked market people are probably still treating it like the old markets.

Or the average predictit user isn't that smart and all linked markets are just going to be extra sweet for us.

A newer poll from this morning shows a 20% margin for Edwards: http://www.brproud.com/news/local-news/democrat-john-bel-edwards-in-the-lead-according-to-new-wvla-poll

I was confused by the party affiliation #s from the poll in the footnotes though: 47%/32%/21% Dem/Rep/Ind - seemed way too high for Dems in a deep south state. A bit of googling makes it seem representative, based on past elections (538 linked to this data from the 2012 presidential: http://electionstatistics.sos.la.gov/Data/Registration_Statistics/Statewide/2012_0701_sta_comb.pdf... I didn't see the real, current data on the official website, but maybe it's out there).

I just put most of my Webb winnings in on Dems at 74c :ohdear:. Looks like voting ends on Nov 21st

The best polls are available now that we're in November - the "by the end of the month X will be at XX" polls. For some reason, people buy a tonne of YES shares at 80 at the beginning of the month. 30 days is a long-rear end time and you are pretty much guaranteed to make a profit riding the dips and valleys.

If the investors in these markets were smart, everything would be about 50/50 until the last week.

edit: Like seriously, Sanders' mark is 25%. He's 27 right now and trending downward since Hillary performed so well last month, and his NO shares are around 15 cents.

So let's say you win on all or most of them. Do you actually get paid $1/share despite having not put much (if any) money in, or is there some algorithm that goes "lol nope" and takes the bulk of your profit? I just really fundamentally don't understand how the linking works.

Part of the $1 you get on any share is the money you put into it so I imagine you get paid the dollar minus whatever the share's cost was when you 'bought' it.

Yeah, all the linking does is make it so that instead of putting up $6 for 10 shares of .60, you get those shares without having to lock up that $6 because you've got $8 already being held to cover a slightly bigger bet.

I'm still a bit confused about what exactly is going to happen. I bought one of each NO market just to test. After all the refunds as I bought them, I ended up being out only $0.05 for the total price of those five shares.

So when the market closes end-of-day Friday, do I get $5 - $1 = $4, and thus realize an 8,000% profit... or...? :confused:

Edit: Oh, I found it, you have to click "Your risk in this market" on "Your shares" to bring up the payout matrix.

Apparently I'm now guaranteed to lose 3-5 cents no matter which way the markets resolve.

No, that 5-cent loss represents the worst case scenario; the sum of winning $1 minus fees and losing out on the shares that resolve to Yes will come out to -$0.05 at worst for you. If they resolve more favourably (say you win on shares you bought for 60 cents instead of the ones you bought for 90) you'll get a little bit more when the market closes.

Short story shorter, that $0.05 already has most if not all of your winnings rolled into it already.

Nah, that means that the most you can possibly lose is $0.05 - your "risk." Since you bought EVERY contract's No shares, you've actually locked in a guaranteed loss of $0.05 if you wait to maturity, since there's only one possible outcome: that four of them resolve to wins and one resolves to a loss.

My first sentence sums up what linked pricing does - "No" shares just became cheaper in multi-contract markets if you buy "No"s in multiple contracts at the same time, since they now only cost whatever your maximum potential losses are. Before, you'd have had to pay $4.05 for those shares, and you'd get back a guaranteed amount of $4.00 for them at the conclusion of the market (because, no matter what, there would be four "correct" No shares, and one "incorrect" No share, since one of them HAS to win).

Now, you only gave to pay $0.05 for those shares, and you can go spend the extra $4.00 that was meaningless to have locked up in that market (since there was no possible outcome in which you'd lose any more than $0.05) elsewhere.

This has no effect on "Yes" share prices, except for the fact that suddenly "No"s are cheaper relative to "Yes"es than they used to be. In multi-contract markets, we might see Yes shares fall in value relative to where they would have been before as a result.

I posted about it last week. I did that and ended making 5% after fees. The only caveat is the fees took an especially big bite. One of them you will lose everything (of course). But 4 you will make a profit on, but you will pay the 10% on 4 sets of winnings. I'm probably explaining it bad. Say there were 5 levels each priced at 20 and you bought an equal number of all. At the end, one of them will have lost you 80, but 4 of them will make 20 each, so you will have won 80. But you will need to pay 10% on your winnings. So really you will net 72, but you will be down 8 once you factor the amount you lost.

It can work if the price of YES adds up to way over 100, but I can see linked trades making NO easier to buy ruining that strategy

And that's very true if you bought in with the plan of making money on being right on November 30. If you're just trying to turn a profit in a week or so, that 15 cents will get to 20 eventually if some poll causes a panic. And don't be too shocked when o mallet stays to poll a little more favourably. Nothing over 5, of course, but I dont think he's as much a non entity as webb or Chafee was.
