Forecasting polls
One question per market: what do you think the probability is? Answers are pooled into a crowd figure and shown beside the venue price. No money, no prizes, no ranking by profit — and no aggregate until 8 people have answered, because a median of four is just one opinion with a decimal point.
Venue prices are the last stored capture, not a live quote. A gap is an observation about a sample, not a suggestion to trade: crowds are often wrong together, and a poll is not advice.
