A multicriteria optimization approach for the stock market feature selection

Abstract

This paper studies the informativeness of features extracted from a limit order book data, to classify market data vector into the label (buy/idle) by using the Long short-term memory (LSTM) network. New technical indicators based on the support/resistance zones are introduced to enrich the set of features. We evaluate whether the performance of the LSTM network model is improved when we select features with respect to the newly proposed methods. Moreover, we employ mul-ticriteria optimization to perform adequate feature selection among the proposed approaches, with respect to precision, recall, and Fβ score. Seven variations of approaches to select features are proposed and the best is selected by incorporation of multicriteria optimization.
