20 11.1 Disabling of DRK Orders Market or technical issues may require DRK orders to be disabled by TSX/TSXV Trading Support at the symbol or market level due to market issues such as triggering of volatility parameters or technical issues such as an away market sending erroneous quote data. When DRK orders have been disabled at the symbol level, all DRK orders for that symbol will be transitioned into a non-executable state and a stock status notification will be disseminated with the Accept Undisplayed value set to “N”. This will be followed by a General message being disseminated by TSX/TSXV Trading Support as further notification of the action. When DRK orders are disabled by TSX/TSXV Trading Support at the market level, all DRK orders on the market will be transitioned into a non-executable state. This will be followed by a General message and an email being disseminated by TSX/TSXV Trading Support as notification of the action. 11.2 Re-enabling DRK Orders 11.2.1 Symbol level Once DRK orders have been disabled at the symbol level they may be re-enabled intra-day by TSX/TSXV Trading Support. Once re-enabled a stock status notification message will be disseminated with the Accept Undisplayed tag set to ‘Y”. This will be followed by a General message being disseminated by TSX/TSXV Trading Support as further notification of the action. 11.2.2 Market level When DRK orders have been disabled at the market level they may re-enabled prior to or after the continuous trading session by TSX/TSXV Trading Support. This will be followed by a General message being disseminated by TSX/TSXV Trading Support. 12. Order Entry DRK orders may be submitted through the TSX-FIX protocol. Please refer to Table 2 for a summary of the corresponding tag details, or the TSX-FIX Specification and Business Design Guide for full details. • When a DRK order is booked the limit price will be reported in the Price field of the order confirmation. • When a trader CFOs the price of a DRK order this will result in a new limit price being assigned. 13. Broadcast Feed • All pre-trade messages generated as a result of a DRK order will be fully encrypted. • All trades where the passive side was a DRK order will be marked with the public indicator IsDark = Y on the corresponding trade report. • All CMO+ to CMO+ trades will be flagged as IsMidOnly = Y on the trade reports to publicly identify that this is a trade between two CMO+ orders. • All Conditional trades will be flagged as IsConditional = Y on the trade reports to publicly identify that this is a trade between two Conditional orders.
