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.
