本文主要是利用Cao,Hansch and Wang(2009)的方法，套用在台灣期貨市場中來研究限價委託簿，了解投資人日內下單的狀況與報酬的關聯來觀察市場上之限價委託單是否有資訊存在，本文利用四種期貨商品日內交易資料重建了不同時間點的限價委託簿原始情況，我們將不只獲得最佳的五檔的報價及未成交量資訊，同時可以清楚明白未成交量是由何筆限價委託單及何種投資人所委託構成，利用迴歸分析後，本文發現大台指與小台指期貨契約中，國內機構法人所擁有資訊最多，外資次之，期貨交易人所擁有之資訊最少，而在金融指與電子指數期貨中，期貨交易人所擁有資訊反而為最多，國內機構法人次之，外資最少。本文接著利用各期貨契約限價委託簿全市場資料所含之資訊性來制定交易策略，以進行日內高頻交易的方式來獲取正報酬。 This paper use the method of Cao,Hansch and Wang(2009) for the Taiwan futures market’s limit order book, we discuss the information content of market limit order book by the relationship of investors’ intraday order and the return.
