Block trades are to be executed within normal contract trading hours (including the night session), plus 10 minutes after the close. For example, normal ASX Trade24 trading hours for ASX SPI 200 index contracts are currently 9:50am to 4:30pm and 5:10pm to 8:00am. Block trades could, therefore, be executed 9:50am to 4:40pm and 5:10pm to 8:10am.
For night session only block trades, trading is restricted to during the night trading session hours, that is, 5:10pm to 7am (7:30am during US non-Daylight Saving Time).
The BTF may only be used to arrange and execute trades equal to and above pre-defined volume thresholds in prescribed ASX 24 contracts.
