This paper proposes the design of a trading system that takes into account any generic pattern that has been proven to be profitable in the past, without restricting the search to the specific technical patterns reported in the literature, hence the term generic pattern recognition. A fast version of dynamic time warping, the University College Riverside subsequence search suite (called the UCR suite), is employed for the pattern recognition task in an effort to produce trading signals in realistic timescales. This paper evaluates the significance of the relation between the system's profitability and (i) the pattern length,(ii) the take-profit and stop-loss levels and (iii) the performance consensus of past patterns. The trading system is assessed under the mean-variance perspective by using 560 NYSE stocks. The results obtained by the different parameter configurations are reported, controlling for both data-snooping and transaction costs. On average the proposed system dominates the market index in the mean-variance sense. Although transaction costs reduce the profitability of the proposed trading system, 92.5% of the experiments are profitable if the analysis is reduced to the parameter values aligned with the technical analysis.  \nKEYWORDS:  \nStock markets, technical analysis, dynamic time warping, UCR suite, generic pattern recognition  \n1  INTRODUCTION  \nAutomating trading decisions, submission and management of trading orders through the use of computer algorithms is a common definition of algorithmic trading (Hendershott, Jones, & Menkveld 2011) . Many algorithmic trading systems have been proposed, particularly aimed at achieving the automation of trading decisions (e.g. Feuerriegel & Prendinger 2016; Geva & Zahavi 2014; Leigh, Modani, & Hightower 2004; Leigh, Purvis,& Ragusa 2002) . The trading rules embedded in these systems generate trading signals, such as long, short and out-of-the-market (Baía & Torgo 2017), by considering various inputs, including market sentiment and technical factors (e.g. Feuerriegel & Prendinger 2016; Nguyen, Shirai, & Velcin 2015) .  \nRegarding the latter, a rich assortment of technical tools can be found in the voluminous literature on Technical Analysis (TA) . The celebrated classes of these TA tools are technical indicators (Kim & Han 2001; Metghalchi, Marcucci, & Chang 2012; Pätäri & Vilska 2014), candlesticks formations (Lu & Shiu 2012 2016) and chart patterns (Tsinaslanidis 2018; Zapranis & Tsinaslanidis 2012a) . However, considering chart patterns in an automated trading system is a challenging task. Although technical indicators such as moving averages, MACD and RSI are easily expressed in mathematical form, the identification an","cbCaiawLhEPHYZHU","https://ap.wps.com/l/cbCaiawLhEPHYZHU","pdf",1689468,19,"English","# Summary\n# Keywords\n# 1 Introduction","[{\"question\":\"What problem does the paper address in technical trading systems?\",\"answer\":\"It addresses how to automate chart pattern recognition for trading purposes, using a generic approach rather than restricting search to a fixed set of literature patterns.\"},{\"question\":\"Which method and tool are used for pattern recognition?\",\"answer\":\"The system uses a fast version of dynamic time warping, implemented via the University College Riverside subsequence search suite (the UCR suite).\"},{\"question\":\"How is the trading system evaluated and what do the results indicate?\",\"answer\":\"Evaluation follows a mean-variance perspective on 560 NYSE stocks with controls for data-snooping and transaction costs; on average the system dominates the market index, though transaction costs reduce profitability.\"}]","What makes trading strategies based on chart pattern recognition profitable? | PDF",1791910652,7]
