Abstract | The portfolio management for trading in stock market poses a challenging stochastic control problem of significant commercial interests to finance industry. To date, many researchers have proposed various methods to build an automated portfolio management system that can recommend financial decisions for daily stock trades. However, most previous attempts to predict future returns of stocks have been largely unsuccessful due to the high complexity of integrating price prediction results with trading strategies. Motivated by this, this paper presents a new stock trading system, named Q-trader, that can overcome the limitations of the existing approaches through the joint optimization of the prediction results and the corresponding trading strategies. Specifically, the proposed framework employs four cooperative Q-learning agents that adaptively interact with their environments by use of feedforward neural networks. In order to achieve computational efficiency for global trend prediction, a novel data structure is proposed for compact representation of long-term dependencies of stock price changes. Experimental results on KOSPI 200 show that the proposed approach outperforms the trading systems trained by supervised learning both in profit and risk management. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
