On November 8th, the SEC granted immediate effectiveness to NYSE Arca's proposed modification of the functionality of Tracking Orders to eliminate the current cancellation feature. The Exchange proposes that upon partial execution of a Tracking Order, the Tracking Order would not be cancelled, but rather the remaining portion of the order would repost in the Tracking Order Process with a new time priority. Comments should be submitted within 21 days after publication in the Federal Register, which is expected during the week of November 15. SEC Release No. 34-63272.
