There are extensive rules and regulations that Market Regulation may impose, and each exchange has its own rulebook. Violating any of the rules will first result in attempts to resolve the violation through an approved settlement, however certain violations must be resolved in the audience of an arbitration panel and approved by the Business Conduct Committee. Know your exchange’s rulebook before you trade.
