23 Example: Post Only Feature Assume the CLOB is as follows: BID OFFER Order # Quantity Price Price Quantity Order # 005 1,000 10.01 10.02 DRK 400 002 001 100 10.00 10.02 100 003 10.03 200 004 If an incoming Post Only order to buy 300 shares @ 10.02 is entered, then it will be rejected because it is entirely executable. If an incoming Post Only order to buy 1,000 shares @ 10.02 is entered, then it will be rejected because it is partially executable. If an incoming Post Only order to buy 1000 shares @ 10.01 is entered, then it will book (see order 005) and the resulting CLOB will be: BID OFFER Order # Quantity Price Price Quantity Order # 005 1,000 10.01 10.02 DRK 400 002 001 100 10.00 10.02 100 003 10.03 200 004 3.5 Drop Copy Drop Copy is a risk management tool designed to facilitate real-time monitoring of trading activity on all three TMX equity marketplaces. It allows trading participants to define a secondary destination through an additional session connection for copies of all trades and cancelled trades (if any) for each order entry session. Order messages are not included on Drop Copy sessions. Setting up a Drop Copy is facilitated by Trading Services, with safeguards in place to ensure only authorized persons can request a drop copy and private trading information is kept confidential.
