If mkt>50% resolves to PROB=mkt^2, otherwise resolves to PROB=sqrt(mkt), rounded to the nearest integer percent.

By mkt I mean the market's predicted probability or "chance" as shown by the interface at close (a 2-or-3-decimal number between zero and one). For example, if the "chance" predicted when the market closes is:

60%, resolves to PROB=(0.6)^2=0.36 =36%

1.3%, resolves to PROB=sqrt(0.013)≅0.11402 ≅11%

Market closes at some random time during Monday 1/23/23 EST unless there's trading within the latest 60 min, in which case it closes at a random time between 30 and 60 minutes later regardless of any further activity. I will not actively buy any shares past Sunday EST, but I reserve the right to set protective limit orders or liquidate all or part of a potentially losing position up to when I first check the market on Monday.
