Currently, due to cost basis loans, trader bonuses, and liquidity subsidies, Manifold "stocks" - permanent markets - are net sources of free mana.

This could be changed to make them mana sinks. Eg, maybe users could burn mana to move the price up or down further than they could by buying and selling.

Resolves YES if they are clearly overall mana sinks at market close, NO if they are still mana sources, and PROB if it is unclear to me.

This is somewhat subjective and I won't trade in this market as a result.
