由於技術分析之有效性一直為學者們所探討且備具爭議的議題，有部分學者認為技術分析無效，但實務上，技術分析在金融市場上的應用卻相當廣泛；此外，由於外匯市場為交易量龐大且眾多學者研究之重要金融市場，故本文回顧過去多項國內、外研究，並經由實地探訪台灣外匯市場上之投資人，針對仍未被研究，但實務上所採用之技術指標進行多項交易策略之模擬並探討其獲利性。
本文主要針對新臺幣兌換美元之匯市，探究將商品通道指標(Commodity Channel Indexes)及威廉指標(Williams Overbought/ Oversold Index)兩種技術分析指標應用於此外匯市場上之獲利情形，採用1993年1月1日至2012年12月28日，共計二十年，5279筆銀行間交易之新台幣兌美元之匯率日間資料，擷取其最高價、最低價及收盤價並透過程式交易進行回溯測試，並針對此兩種技術指標建構多種交易策略，歸納並分析其中可獲得超額報酬之技術策略，期能找出獲得最佳投資報酬以及提高交易的成功機率與獲利能力之法則。
藉由Matlab運算處理後，將此兩種技術指標應用於過去20年之歷史價格進行回溯測試，本實證研究發現：1. 採用威廉指標之策略普遍績效都較採用商品通道指標來的好，不僅在總報酬率的表現上比較好，採用威廉指標所執行的交易獲利的機率也必較高。2. 由於此兩技術指標應用在新台幣兌美元之外匯市場上可得的績效高於買賣策略應用於此市場之平均年化報酬率，故證實此兩種技術指標應用在新台幣兌美元的外匯市場上，均可獲得超額報酬，此兩技術指標在新台幣兌美元市場是有效的、可獲利的。 / It has long been a controversial question to scholars whether or not technical analysis is efficient. Although some scholars believe technical analysis is useless, it has been broadly used in the financial markets for a long time. As foreign exchange markets are one of the most important financial markets with huge trading volume in the world, this paper reviews many past literature and extracts trading strategies from some real investors in Taiwan’s foreign exchange markets. Additionally, this paper focuses on testing the trading performance of applying the technical indexes which have not been researched in the academic field but have often been utilized in the real exchange markets.
This thesis mainly concentrates on the exchange market of New Taiwan Dollar against US dollar and examines the trading performance of utilizing two technical indexes which have been used but not been researched in foreign exchange markets : Commodity Channel Index (CCI) and Williams Overbought/Oversold Index (WMS). The dataset of this paper is from January 1st, 1993 to December 28th, 2012, an overall of 20 years and 5279 times of daily NTD/USD exchange rates between banks. To complete the back-testing, this research utilizes the highest, lowest and close price from those materials and analyzes the technical strategies which obtain excess profits. By generalizing the results of those trading strategies, investors can find the best trading rules and increase the returns from applying these two technical indexes to foreign exchange market.
The results of this research are as follows: 1. WMS’s performances are chiefly superior to the CCI’s performances. Not only the total profit rates of technical strategies from WMS are higher than the total profit rates of trading rules from CCI, but also the rates of profits on WMS always demonstrate a better result than the rates of profits on CCI. 2. Both of these two technical indicators can produce excess profits. Compared to the average annual return of buy-and-hold strategy in this market, both of the two technical indexes conduct a better performance. As a result, these two technical indexes are effective in NTD/USD market.
