Limit orders cancelled on all markets if cash goes below zero

Rules: - Eligible answers must be submitted before the bug is fixed - Answers cannot be submitted by Manifold employees - The market resolves once 5 eligible bugs are fixed, each of which gets 20% of the pool. I hope this is good way of surface bugs that we should be fixing! I'll add an ante so you can be incentivized as well.

Jul 16, 5:13pm: Thanks for reporting the bugs everyone! Resolved.

Huh, my bets bidding an answer up to 30% lost me money even when other bets ultimately pushed the probability down to 20%. I really don't know how to reason about bets on these parimutuel markets

@jfjurchen Yeah, you would only want to buy up to 20%. Otherwise, you are paying more per share than you would get out for winning. It's about the price you pay for a share vs. it's final price.

@MartinRandall Cool! I think this is the 5th bug fixed.

@Gigacasting I think I fixed another case here, so counting this as fixed.

@Gigacasting On reflection, cancelling all a user's limit orders is not ideal. Will try to move to the model of cancelling them one-by-one as they are attempted to be matched.

Thanks for fixing!

And limit orders taking user into negative cash (triggering the rest to be cancelled vs cancel-one)

@JamesGrugett still happening

See https://manifold.markets/SG/what-is-the-worst-thing-about-manif#CdRWFOkx0C0eQBeGqwCA Also noticed some of the “top” accounts had lost money over the windows they were supposedly the highest on

@Gigacasting Fixed this! Thanks for reporting. That's 4 out of 5 for this market.

@ian I've been getting occasional "aw snap" on Android Chrome, could be linked. Started today.

@Gigacasting hm this sounds pretty bad! I don't have an iPhone but @SG might be able to repro

Possible something changed mid-day, or possible it’s just a one-off cookie bug local to my browser…

@ian unusable on iPhone 13; pages refresh and crash; phone is hot (only site to ever trigger a hot phone)

@Gigacasting what do you mean by heat?

@Gigacasting Could have been! Though buy M$1 would always have fixed it. I'm interested to hear if anyone else thinks this is still happening.

(Might have been previously filled before fix, cleared with buy $1)

Own YES and NO on https://manifold.markets/BTE/will-trump-be-charged-by-the-grand

@LivInTheLookingGlass I think the code should be able to deduce it based on the MIN and MAX, but I don't know what charting widget you're using. Date range markets would also solve this problem.

@MartinRandall I really wish you could specify the amount of rounding at market creation. This is the first I've seen that's outright broken, but there have been several others where real information gets lost

https://manifold.markets/MartinRandall/in-what-year-will-a-10yo-girl-in-oh Annoying.

@ahalekelly This should be fixed now, as the third bug for this market. Let me know if you can still reproduce for newly-filled limit orders!

@ahalekelly This is the second winner after Stephen's fix!
