So far, no one has traded in a market I have created. This resolves YES if at market close, the total position size (YES + NO) in all of my markets is at least 100 shares. If you trade in this market, your positions won't be counted. My positions won't be counted.

Edit to clarify: For this to resolve yes, the SUM of position sizes across my markets combined (except positions by users that traded in this market) must be >=100 shares.
