“…The last decades have been fertile in research regarding optimization techniques applied to Finance, e.g., (Meade and Salkin 1989), (Lee and Eom 1989), (Suganya and Pai 2012), (Hsu 2014). Important results are based on TA inspired models with respect to Forex markets (Olson 2004), (Schulmeister 2008), (Schulmeister 2009), and use of GA (Lo et al 2000), (Hryshko and Downs 2004), (Chiam et al 2009), (Pavlova and Parhizgari 2011), (Mendes et al 2012), (Godinho 2012). Some new articles -(Pavlova and Parhizgari 2011), (Bajgrowicz and Scaillet 2012), (Lin et al 2011), (S.-W. Chen 2010), (Fang et al 2014), (Kuang et al 2014) -question, in a more empirically sustained way, the value of TA in achieving abnormal excess returns, especially when taking into account trading costs.…”
