Market Simulator
We simulate the market by
1). replaying historical limit-order-book-level data;
2). simulating the order matching mechanism.
Currently, the codes work well for minute-level data, i.e., one-step = one minute, which can be altered.
State: a stack of market indicators and market snapshots over the past several time steps.
Action (raw): an order placement. We suppot market orders and limit orders.
Reward: can be configured by the contestant with the aim to generate polices that can optimize pre-specified metrices.
We also provide several wrappers to accept conanoical discret or continuous actions.
We consider the following factors:
1). Temporary market impact;
2). Order delay;
We do NOT consider the following factors yet:
1). permanenet market impact of limit orders;
2). non-resiliency limit-order-book.
