Copy of https://manifold.markets/Undox/will-any-single-trader-be-able-to-m, because it seemed to be fun. The profit is calculated as Σ(money collected by selling bets) - Σ(money spent on bets) Any "holdings" of YES/NO do not count towards this. This means the profit reported in on the page is ignored, as this is unrealized profit. Will use the values on the page, which are rounded, to do the calculation. So under the hood you may have made 99.9 profit, but if it says 100 when I add it up on the site it is 100.

Here is a spreadsheet with all the bets https://docs.google.com/spreadsheets/d/1fxqXu1Akicxju1vcuyL22ZpZd-uSGTb14zZvImCjgW8/edit?usp=sharing
predicted YES
On row 109 BTE sells his 940 No shares for M$250 and bringing the price from 98 to 6 0.23 seconds later, it says he redeemed 0 Yes shares and 0 No shares from the liquidity pool for M$0? No idea. 13s later MattP sold his No shares, bringing the price to 21 15s later I bought my Yes shares, bringing the price to 97 People who had liquidity at some point: MattP, BTE and Gurkenglas
predicted YES
On line 101, I think BTE put money into the liquidity pool and somehow got given M$26.8 of No? I thought you only got shares in your account when you withdrew from the liquidity pool? And then 0.4s later he redeemed 0 Yes shares and 0 No shares for M$0, same as above. That was all of BTE's liquidity pool interactions.
predicted YES
Similarly, line 90 it says Gurkenglas put money into the liquidity pool and was given M$12.5 of No? And that was his only liquidity pool interaction.
predicted YES
Asking in Discord
I checked Adrian and MattP on my script and they are both well in excess of 100 profit.
bought Ṁ100 of YES
Wait I'm up 128, how did that just happen
@ahalekelly LOL I sold my 22 of NO, I think that is why. Pushing the prob in your favour. Well done!
predicted YES
Kept one share as a memento
I calculate @MattP has made 137 so will resolve YES soon. I just want to give a bit of time for anyone in the NO camp to check and tell me if I have it wrong. If I hear nothing I will resolve.
@Undox Agree that Matt is over 100. I think you miscounted (even accounting for rounding) because on his bets page I see profit of 149 with 1 remaining share of YES, but certainly north of 100.
predicted YES
@jfjurchen that profit number isn't necessarily super reliable, it gets confused with liquidity shenanigans especially. I think the criteria Undox is using is just adding together all transactions in the betting log, which seems more foolproof now that liquidity withdrawal shows up correctly-ish.
predicted YES
Both methods ignore liquidity shenanigans. It's just that in this market it wasn't possible to profit from those liquidity shenanigans.
predicted YES
@ahalekelly what causes the displayed profit and the totted up profit to be different in this case, do you know?
predicted YES
@MattP Rounding error is my guess, the bet log rounds each bet and the profile page rounds the total?
predicted YES
@ahalekelly mmm, it's an error of about 10%. I think something else is going on.
@MattP Hm, did you not engage in any liquidity shenanigans? Just looking at your "bets" page, I see the same thing - summing the bets gives 136, but it shows 149 profit. Suspiciously, it also says "12 YES shares and 12 NO shares automatically redeemed for M$12." - M$12 is about the size of the non-rounding discrepancy.
@jfjurchen I have been getting messages those on a lot of markets.
predicted YES
@jfjurchen I did a few liquidity shenanigans, in the sense that I injected and immediately removed once or twice to buy shares without moving the probability.
bought Ṁ26 of NO
Somehow just ended up with -1 shares after buying $250 of NO
sold Ṁ110 of NO
Curse your fast fingers, Adrian!
Now for the question.... do I buy back in to eliminate my profit, since I no longer stand to make more?
bought Ṁ1 of YES
@Undox pretty sure I just did it btw
predicted NO
@MattP Any idea how I ended up spending $250 on -1 shares?
sold Ṁ22 of NO
@MattP looks like 137 you made to me, do you agree?
predicted YES
@BTE Wild. Looks like that money went to @MattP and I somehow. Let me check the API logs
predicted YES
@Undox my count is M$136, so that jives (I bought M$1 of YES probably around when you made that count).
predicted YES
@BTE odd. I stopped for gas and just happened to check this market. Saw that it was near 0% and sold my NO. Wondering if it was in close enough proximity to your trade to somehow mess something up, though that would be pretty surprising.
