Right now all binary (Yes/No) questions open by default at 50%. This seems arbitrary to me (although maybe there are mathematical reasons for it), and gives an advantage to those who are merely first to trade in the right direction.
This resolves yes iff Manifold allows creators of a Yes/No question to set the opening price to any percentage other than 50% at any point between now and close of this market.
I won't trade in this market.
They used to allow this in the ui. Removed it because people could initialize at the other spectrum of the scale, say at 1% and correct it to 99% for a 98% correction and huge initial share profit that would show up in the trader leaderboards.
Besides if you initialize it right at the correct % there is no point in betting in the market unless you disagree.
This has never bothered me because for every market I've created, I've always had the ability to trade it down or up to what I think the starting price should be before anyone else does.
I suppose that gets pricier as you move towards extremes and if you think the starting price should be like 0.05, perhaps this is useful.
