Limit order: price × shares ≥ 1 PTS. Market buy ≥ 1 PTS. Market sell ≥ 1 PTS (no minimum for market close-out orders).What is a mirror order? Within the same market, Yes and No are complementary assets (1 Yes share + 1 No share = 1 PTS). Therefore, "buying Yes at 0.60" is equivalent to "selling No at 0.40," and "selling Yes at 0.60" is equivalent to "buying No at 0.40." The system automatically generates mirror orders to facilitate trade matching.Can I sell before an event concludes? Yes.
