Resolves based on the status of the linked market at close, by going to "positions" tab and sorting by profit. If my position is lower than -0M, that counts as a loss and this market resolves YES. (If I'm in the red but it's -0M, this market resolves NO.) 

I promise not to deliberately lose mana in the linked market, and I won't take a YES position in this market so I won't have any incentive to do so. 

This market is intended as a bet regarding whether betting NO in markets like the linked one is "throwing away mana". 

Edit: to clarify, I mean when the linked market resolves. (That was probably obvious, but I don't want there to be any confusion about the words "close" and "resolve".) It's the actual mana I win or lose, not the hypothetical "here's what your position is worth" measure.
