Effective today, orders of up to 250 contracts in the 50 most active option classes and orders of up to 100 contracts in the next 50 most active classes can be routed to the Amex's auto-execution system for options. Auto-ex for these sizes will be available for both customer and broker/dealer orders.
"The American Stock Exchange is committed to meeting the growing demand for increased execution speed in orders of greater size," said Michael T. Bickford, senior vice president for options at the Amex. "Today's auto-ex increases work hand in hand with our TAO application to reduce execution times for our customers."
