The one trap

The report the resolution source shows for a given observation time is the one that counts, whether or not it is marked as a correction (COR).

See all fine print

In the case that the Resolution Source publishes data, sufficient to settle a Market, that is clearly erroneous and the result of technical or operational error, or of unauthorized interference with the Resolution Source or its data, the Market may remain open for a period of up to seven (7) calendar days (ET) from the time of the original release, in anticipation of a correction by the Resolution Source.
