This is a work of art, it would be wonderful to find examples inspired by you with PPO and other agents.

I uncommented and tried to test the DQN_Agent in https://github.com/druce/rl/blob/master/Trading_with_RL.ipynb https://github.com/druce/rl/blob/master/Trading%20with%20RL.ipynb because even if it is slow, it still has great value for those who are learning, like myself. I only removed the “import resources” and its dependents because I am running it on Windows

I tried "
N_EPISODES = 10000
ticks_per_episode = 1256
nstocks = 1

env = Market(shm_market_gen,
nstocks=1,
episode_length=ticks_per_episode)

agent = DQN_Agent(state_size=nstocks*32,
action_size=2,
)

start_time = time.time()

for e in range(N_EPISODES):
agent.run_episode()
agent.score_episode(e, N_EPISODES)

if e and (e+1) % agent.save_interval == 0:
    agent.save()

elapsed_time = time.time() - start_time
print("Train time: ", elapsed_time)
agent.rlplot()"
Unfortunately, I got:
