On November 11, 2009, the NYSE issued an NYSE Trader Alert informing clients the NYSE would institute a temporary processing change to automatically cancel all open GTC orders and replacement orders that received a partial fill or were partially canceled during the trading day. As a result of customer feedback in response to our November 11 notice, the Exchange has determined not to move ahead with this automatic cancellation procedure. Please see the attached memo for additional details.
