Will this market get >x Mana traded?

These are my "Will this market get more than x total Mana traded before close?". They each last for up to 20 days. When one of them resolves, I create a new market, increasing or decreasing the target based on the result of the previous question. It's interesting to see the strategies people are using. For example, already someone has added liquidity, and someone else has bought/sold repeatedly.
