On March 14, 2011 TSX Markets integrated the TSX/TSXV Dark Midpoint and Dark Limit order types with Canada's most extensive displayed order book providing tremendous value to all market participants by offering meaningful price improvement, significantly reducing trading costs and increasing valuable liquidity seeking options.
The Dark Midpoint and Dark Limit order types both provide full pre-trade anonymity and are eligible to match against all liquidity submitted to the Toronto Stock Exchange and TSX Venture Exchange. Providing our customers with continuous interaction between the dark and displayed books maximizes the value of additional execution opportunities and liquidity seeking options.
The Dark Midpoint order will only execute at the mid-point of the NBBO (National Best Bid/Offer) and may be submitted with an optional limit price. The Dark Limit order will only execute at or within the NBBO.
An optional Minimum Quantity instruction is available for Dark Midpoint orders which will prevent the order from participating in a trade unless the tradable volume meets or exceeds the volume specified through the Minimum Quantity instruction. The Minimum Quantity instruction will only be accepted if the volume provided in the Minimum Quantity tag meets or exceeds 20 standard board lots. To better assist institutions and users in reducing market impact and to enhance TMX Dark Order types as a valuable facility for the execution of larger sized orders, Dark Midpoint orders with a Minimum Quantity instruction will receive fill priority over other Dark Midpoint orders without this condition or Dark Limit orders at the same price level.
For a detailed description of our dark order types and their attributes please see the "Toronto Stock Exchange, TSX Venture Exchange Dark Liquidity Guide" available through the link below.
