This market will be a random walk. It's underlying true probability will move up and down in steps according to randomness generated in the comment section. You can generate a bit of randomness and then buy/sell to the new value, and always have positive expected value by doing so.
To participate, use the FairlyRandom bot to generate a number 0-1, by making a comment “@FairlyRandom min=0 max=1”. If the bot returns 0, the true probability goes DOWN by the step size, if it returns 1, it goes UP by the step size.
THE STEP SIZE FOR THIS MARKET IS 5
If the underlying true probability ever hits 0, or 100, it will resolve to NO or YES respectively, and no further rolls will matter. (Pay attention to this). Otherwise I will either resolve to the true probability numerically, or use it to generate a YES or NO answer probabilistically.
I have another market at https://manifold.markets/YaakovSaxon/math-proof-question-re-random-walk?r=U2hpdGFraUludGFraQ, concerning the math of this market, which is presently at 98% that my math is correct. See there for further discussion.
You may roll again if 10 people have rolled since the last time you rolled.
Note that this is the second iteration of this market, with the step size reduced to 5, as the first market resolved much faster than I was expecting.


@Redact I think it would be cool if the market automatically progressed on its own at regular intervals but individuals were allowed to add their roll to the market progression under some rules, but it should not require a special audit to tell what the market status should be. So like a trusted automated calculator.
@ShitakiIntaki Do you have a final count to which to resolve the market?

@YaakovSaxon no change since my last post 13 days ago. R2D2 was the last valid roll, market odds at 65%

@howtodowtle , @SneakyElbow , @JimHays , @A , @HarishGanesan , @Redact , @OrlandoMoreno , @blake , @viluon , @Odoacre , @PeterBerggren , @AndrewHalsell , @Devansh , @NicholasJarrett , @enaz , @Celene , @Lorenzo , @Conflux , @Renz , and @eacc are all eligible for re-rolls.

Interesting quality of a random walk with stopping points, the expected number of steps till resolution is equal to the product of the distance in steps the walk is from each stopping point, so this market started out with an expected 100 (10 x 10) rolls to complete. We are now at 63 valid rolls in and have an expectation of 91 (7 x 13) more rolls to go.....

@YaakovSaxon may consider taking out an ad, or resolving to market; no new rolls in over a week.

This market should probably be added to the market description, since it has a conversation and references to mathematics supporting the premise that the probability of a random walk on the interval of 0 to 1, where 0 and 1 are stopping points, resolving to 1 is equal to the current position of that random walk. i.e. if the position of the random walk is 0.5 then the probability that the random walk will reach 1 before reaching 0 is 50%.

Today I learned you can look at the market in terms of profit rather than shares. Although I am not sure why there seems to be a discrepancy between what the positions sorted by profit reports vs what my summary according to average cost accounting reports.

@R2D2 is now the most recent user to be come eligible for a reroll.


@R2D2 You found "me." I thought it was such a cool thing to exist out there in the world.

@R2D2 No, I have not. I have done very limited traveling but this would certainly be on my list of places to visit.
@ShitakiIntaki btw, I got a 0 on my reroll and the market was 70%, do I corrected it down to 65% (5% steps) by buying more NO shares. Was this the mathematically correct (in expectation) thing to do? I don't understand much about random walks, but I'm following the min-tutorial you gave me some time ago 🙂

@R2D2 Yep. You did right by your self and should have a positive expectation for adjusting the market down 5%, from 70% to 65%. I also am trying to post a new audit with each roll to help people returning to navigate this rather robust comments section.

Noticed that every once in a while @FairlyRandom would spam duplicative responses which I was picking up as extra rolls. I have since used the Salt to identify unique rolls. Here is a count of rolls vs valid rolls after filtering out any duplicative Salts.

@ShitakiIntaki I would note that the last roll should look at the last valid roll. An invalid roll doesn’t reset the clock to your detriment, it just gets treated as if you hadn’t rolled

@YaakovSaxon Reindexed to explicitly count number of valid steps between rolls by the same person. Same market audit result but dispels ambiguity where "since last" was subtracting/counting itself based upon whether or not it was valid itself.


@YaakovSaxon Ah I see where I am miscounting... have it looking to last time the rolled but should instead look to last time they rolled and it counted towards the market, I.E the MordecaiWeynberg reports 2 and 7 but it should report 9 and 7.

@ShitakiIntaki @YaakovSaxon I need to figure out how to do this not in a spreadsheet, starting to get a lot of circular references trying to eliminate edge cases where the validity of each roll is dependent upon the validity of the prior rolls. Fixed the Mordecai edge case

@ShitakiIntaki I don’t understand this market very much. I don’t really see how it is free money. Do you understand? Should I sell? Roll again? 😵💫

@R2D2 So Yaakov has another market over here.... (link below) where we talk about the math, in a perfect market with no fees the math works out. The Summary would be that each time a valid roll move the underlying market odds, you will have a positive expected return if you correct the market. The positive expected return might be a net of 3 mana for an investment of 115 mana so the margins are less than 3%. The crucial thing to know is that every market has winners and losers, so someone will lose money, and on top of that there is also a flat fee that is charged each time you trade that can make the small margins not worth your time. There is no cost to rolling. If you do roll, and I believe your roll would count according to my audit, then you would have an information edge against most traders in knowing what direction to correct the market. But you don't have to correct the market you can choose to sell now while YES is high and walk away with a guaranteed amount.

@ShitakiIntaki theoretically free money because you can correct the market, but only on average in the expectation. It is not Risk Free. Someone will lose and someone will win, even if the market resolves to Market Odds rather than Yes/No.
@ShitakiIntaki what do you mean exactly by "correcting the market"? I can roll the dice again now, since 10 rolls passed since my last roll. Say I get a 0, what should I do? Sell my YES shares? Buy NO? Vice versa, If I get a 1, should I buy more YES?

@R2D2 So if you get a 0, then the market odds will move down by 5% to 65%. The current Market is at 70% so you would correct it by buying NO or selling YES till the market odds reflect 65%. Visa Versa, if you get a 1, then the market odds will move up by 5% and the correction would be to move the market from 70% to 75%.

@ShitakiIntaki @YaakovSaxon Are these market audits consistent with the ruleset you will use when resolving this market if 100% or 0% does not happen first?
@ShitakiIntaki I haven’t audited your audit to see if you’ve done it accurately, but your approach seems correct, yes
@YaakovSaxon Btw I’m thinking to change the reroll waiting period from here on out (not retroactive) to 5 instead of 10. Any objections?

@YaakovSaxon I think it will be tricky to clearly communicate when exactly the new rule starts and the old one sunsets since you are not going to be retroactive. This is not to say that I support a retroactive change because any shift in the probability because of a retroactive rule change would be like a rug pull since it would move prior bets out of maximal expected return.
