Trading rules
The venue operator's document covering admission, order types, trading modes and what the parties do when something goes wrong.
How to read the number
Everything a participant takes for a property of the market — the available order types, the length of phases, the grounds for a halt — is written here and changes by decision of the venue.
When the metric lies
The document is revised, and familiar system behaviour stops being familiar afterwards. Past experience is a poor substitute for the edition currently in force.
