Methodology
Maker cancels are computed by diffing consecutive Kalshi orderbook snapshots (~20ms resolution) and subtracting known trade fills from the Dome API. For each snapshot pair, the expected volume at every price level is calculated asstart_volume − trades_consumedand compared against the actual volume in the next snapshot. Negative deviations indicate maker cancellations; positive deviations indicate new maker orders. Results are aggregated into 1-minute buckets across both markets (SEA + NE) and both orderbook sides (YES + NO).
