The RL agent adaptively fuses these states and then executes an actor-critic algorithm in the unified state space. The predictive coding part consists of three Transformer branches with modified structures, which respectively extract effective latent states of long-/short-term future dynamics and asset relations. In this paper, we present StockFormer, a hybrid trading machine that integrates the forward modeling capabilities of predictive coding with the advantages of RL agents in policy flexibility. ![]() Typical RL-for-finance solutions directly optimize trading policies over the noisy market data, such as stock prices and trading volumes, without explicitly considering the future trends and correlations of different investment assets as we humans do.

One way to do this is by normalizing out the full magnitude of the gradient in our standard gradient descent step, and doing so gives a normalized gradient descent step of the form
