The Impact of High-Frequency Trading on Australian Futures Market Liquidity and Efficiency

This article examines the colocation of high-frequency trading (HFT) facilities and capacity of the Australian futures market to absorb information following major scheduled macroeconomic announcements. The findings show that the co-location of HFT facilities has increased trading activities and liquidity across the four futures contracts investigated. The four futures contracts also demonstrate a market capacity to absorb information from major announcements efficiently. For instance, the majority of price adjustments are impounded within 30 seconds following major announcements. The authors conclude that abnormal trading profits are unlikely to be generated by HFT in the Australian futures market.
