有關昨日上午臺股期貨及小型臺指期貨開盤一分鐘內出現跌停價一事,期交所董事長劉連
煜指出,檢視交易系統一切正常,是屬市場單一事件。但期交所仍將持續調查2000多個帳
戶的交易有無不法並送有關單位調查,而未來會推出「動態退單」機制,原預計明年中推
出,現在如果能提前就盡量提前
劉連煜表示,查臺指期貨開盤後受亞洲股市行情影響,因交易人對市場行情的預期,致使
開盤價格10,420點逐步下跌至10,042點附近,指數出現較大跌幅,其後價格區間在10,100
點至跌停價9,408點間來回震盪。
由於因交易資料量龐大,經進一步分析統計後,昨日開盤第1分鐘,臺指期貨第一波段
(10,420點至10,042點)下跌378點,買賣戶數合計1,600餘戶,第二波段(10,100點至9,408
點)下跌692點,買賣戶數合計1,600餘戶。在這1分鐘內,全市場統計交易帳戶買賣戶數合
計約2千餘戶,累積交易量9千多口。經檢視現有事證,該1分鐘內的委託,係由於眾多交
易人因對行情之不同預期,掛出的委託單成交後引發不同交易帳戶交易決策之委託執行,
導致開盤後該時段價格出現較大幅度波動。
劉連煜強調,交易人因本次價格波動有賺有賠,初步洽結算會員瞭解,在這1分鐘內,交
易人自行平倉以及結算會員依風控原則執行代為沖銷者,其平倉虧損部分,約14個交易帳
戶,合計虧損金額約600萬餘元。
鑑於臺灣期貨市場快速發展,交易人各類交易決策更形複雜,為防範程式錯誤下單及委託
簿流動性瞬間失衡等事件發生,期交所已多次與期貨公會、期貨商開會討論,積極研議動
態退單之價格穩定機制,將儘快推出。
期交所表示,動態退單機制是指交易人委託單之可能成交價格,與基準價格(如前一筆成
交價或理論價格)差距達一定範圍時,將直接退回該筆委託單,以防範價格瞬間異常波動
。此機制目的主要是防止錯誤交易、胖手指、程式錯誤等事件發生,且僅針對成交價格偏
離之委託予以退單,不會影響其他交易人的交易。(蕭文康/台北報導)
經過GX90160SS大指正
應為自動退除可能大幅度影響市價的委託單
