A-Blox was introduced on November 29, 2010 to match block orders with a certain size or more (refer to the table below) from investors wanting to trade anonymously. The orders are concentrated and matched separately from the regular session orders. The execution price is the volume-weighted average price (VWAP) of the issue that is calculated after the market close to be informed to the parties.
The information on the block trading including the order quantity and the execution details are not disclosed throughout the session. The only information disclosed regarding A-Blox trading is whether or not there exits any bid/ask order for each security.
