Opening Process

The CFE Opening Process begins with a Pre-Open session, during which Limit Orders and Quotes in simple instruments are accepted for Queuing. Spread orders are also accepted. The Exchange begins trading after the completion of the Opening Process. Pre-Open start times and the time of the transition to Open for each of the products traded on CFE can be found here. Trading hours of test classes (e.g., ZVX) will mirror those of the related production class (e.g., VX).
