Issue while running code

[Nicolas99-9]

I have two issues while running the code, first one is when I try to run a basic environment. After performing the first action, I receive the following error :
ValueError: too many values to unpack (expected 4)
and when I print the output of env.step(action) :
"No key received:Server Control mode: received <{'action': 'hold'}>"

from btgym import BTgymEnv from policy_gradient import PolicyGradient import numpy as np env = BTgymEnv(filename='../examples/data/DAT_ASCII_EURUSD_M1_2016.csv',) done = False while not done: action = env.action_space.sample() obs, reward, done, info = env.step(action) print(reward)

Second issue is related to the rewards, the are equal to 0 whatever the actions I choose.

@Nicolas99-9 ,

Due to Gym API convention it is essential to call env.reset() before taking steps. Try this way:

from btgym import BTgymEnv

env = BTgymEnv(filename='../examples/data/DAT_ASCII_EURUSD_M1_2016.csv',) 

done = False 

init_obs = env.reset()

while not done: 
    action = env.action_space.sample() 
    obs, reward, done, info = env.step(action) 
    print('action: {}\nreward: {}\ninfo: {}'.format(action, reward, info))
    
env.close()

Anyway error message you receive trying to run uninitialised environment should be more informative. Need to sort it out.

As for zero-reward, see related question: #27 .
Pay attention to broker message part of info output when running script above - you'll see 'ORDER FAILED with status: Margin', cause no sufficient cash has been set.
