Data from https://www.weather.gov/wrh/climate?wfo=psr

Phoenix's 100th consecutive day of 100+F temperatures was September 3 https://www.usatoday.com/story/news/weather/2024/09/03/phoenix-arizona-100-degree-weather/75063509007/

https://www.weather.gov/psr/ExtremeTemps says last day of year with a 100+ temp recorded so far is Oct 26. If consecutive days goes past 150, 150 will be judged.

I created this in part to see how the "experimental" numeric market type works, so I'm going to trade in it.

Note the high yesterday (2024-09-15) according to https://www.weather.gov/wrh/climate?wfo=psr was 106F, like 6 degrees higher than hour by hour forecasts were showing. I'm not sure if this is typical, hopefully serious traders have investigated and are trading accordingly. Anyway the streak has reached 112 days. Will it continue today?

I've been trading in this question as I said I would in the description, however I won't trade after the data for a new day has been released at the URL above if it indicates the streak has been broken as that feels like cheating. Of course others are welcome to before I notice and resolve!

Note the 100th consecutive day was September 3 (I incorrectly stated September 2 in the description; updated). The first day was May 27. Today (September 11) the 108th.

Anyone can look at the forecast but here's a writeup of when it might break anway https://www.azcentral.com/story/news/local/phoenix-weather/2024/09/10/when-will-phoenix-drop-below-100-degrees/75143812007/

bought Ṁ3 149-150 YES

I created this in part to see how the "experimental" numeric market type works, so I'm going to trade in it.

It's not clear to me that it's possible to buy "lower"; either option seems to result in "higher" for chosen range. Though I might be misunderstanding something!

bought Ṁ6 108-109 YES

Ah, "higher" and "lower" just preselect ranges above and below current expected value. There doesn't seem to be any way to buy down a particular range, other than by buying up other ranges. Though I might be misunderstanding something else!

Hmm, the "Mike Linksvayerbought Ṁ6 108-109 YES2m" seems to show an implementation detail. I last bought "Ṁ99 of 108 - 120 from 126.00 to 125.56" and 99/13 is...well 7 with a remainder. So though I suspect an implementation detail is showing, I also wonder whether there's an off by one. Also probably I'm misunderstanding something.

bought Ṁ2 110-111 YES

Test.

Another implementation detail leak "92 more trades" (I've made 5, spanning a range of 89 by my eyeball math...hmm 89+5 = 92+2?)

Also noticing the "holders" tab lists the number of traders holding each increment (ranges of 1 in this case, eg 102-103, 103-104, etc). That feels more like that's just how the market works rather than a showing an implementation detail that doesn't strike me as useful to expose in the way it is (such as the above 92 more trades thing).

bought Ṁ23 111-112 YES

Not specific to the numeric result market type, but in case a Manifold person happens to read this thread, another random suggestion: turn down the opacity of Source: manifold.markets so it doesn't obscure potentially important parts of the chart, eg

Couldn't find a question on the current streak.
