DESCRIPTION:In the last two decades\, high-frequency trading (HFT) has beco
 me a common financial market practice. Its impacts on market efficiency\, l
 iquidity and volatility are investigated and discussed across the globe. Wh
 ile this research is mostly concentrated on equity markets\, aspects relate
 d to futures market are also of interest. In this paper\, we study the effe
 cts of high-frequency trading (HFT) on price volatility in Borsa Istanbul i
 ndex futures market. More specifically\, departing from tick-by-tick order 
 and transaction data of futures contracts\, we measure the share of HFT wit
 hin all the transactions and order flows. We examine the interaction betwee
 n low-latency trading and volatility across the entire sample as well as fo
 r the subsamples where volatility is already high and low. Preliminary resu
 lts show that HFT increases volatility on trading days with negative return
 s in stable market conditions. However\, no similar impact is found in time
 s of increased market stress and extreme volatility.\\n\\nContact: Eric Gir
