Query: Deep Reinforcement Learning for Foreign Exchange Trading   Reinforcement learning can interact with the environment and is suitable for
applications in decision control systems. Therefore, we used the reinforcement
learning method to establish a foreign exchange transaction, avoiding the
long-standing problem of unstable trends in deep learning predictions. In the
system design, we optimized the Sure-Fire statistical arbitrage policy, set
three different actions, encoded the continuous price over a period of time
into a heat-map view of the Gramian Angular Field (GAF) and compared the Deep Q
Learning (DQN) and Proximal Policy Optimization (PPO) algorithms. To test
feasibility, we analyzed three currency pairs, namely EUR/USD, GBP/USD, and
AUD/USD. We trained the data in units of four hours from 1 August 2018 to 30
November 2018 and tested model performance using data between 1 December 2018
and 31 December 2018. The test results of the various models indicated that
favorable investment performance was achieved as long as the model was able to
handle complex and random processes and the state was able to describe the
environment, validating the feasibility of reinforcement learning in the
development of trading strategies.
