주가지수선물시장에서 지정가 주문의 체결과 취소에 대한 생존분석

The competing risks duration model is applied to the analysis of the execution and cancellation of limit orders which are submitted to the electronic trading system of KOSPI200 stock index futures market. We find that foreign investors rather than institutional or individual investors less frequently submit limit orders to the market. And more than 74% of the limit orders submitted by foreigners are cancellation orders. The durations of limit orders have very long right tails of the distribution. The limit orders by the individual investors have longer durations than those by foreign investors. In particular, we find that execution durations of foreign investors' limit orders are shorter than their cancellation durations. According to the estimation results of the competing risks model, price aggressiveness has a significant effect on the time-to-execution and time-to-cancellation. In addition, we show that the execution duration is more sensitive to limit order prices and limit order sizes than the cancellation duration. The execution duration of limit orders by all the investors are increasing with the amount of liquidity on the same side of the market. But in the cancellation limit orders, the coefficients have different signs among investors. The execution duration and the cancellation duration of limit orders are decreasing with the amount of liquidity on the opposite side of the market except for the foreign investors in the cancellation limit orders. We also find that the execution duration and the cancellation duration are both decreasing as maturity approaches.
