start to backtest agent = YourAgent()

transactions = [] while not env.backtest_done: state = env.backtest()
done = False while not done: state, reward, done, info = env.step(agent.choice_action(state))

print(state, reward)

    #env.render()
    if done:
        transactions.append(info)
        break

transaction = pd.concate(transactions) transaction
