How to predict current decision

[JustinGuese]

Hey, so to predict the current timestamp what would I need to do?

[JustinGuese]

adding in methods.py the following and calling it from a file similar to eval.py?

def predict_next(agent,data,window_size):
    state = get_state(data, len(data)+1, window_size + 1)
    # select an action
    action = agent.act(state)
    if action == 1:
        print("BUY!")
    elif action == 2: 
        print("SELL! (if you bought a stock")
    else:
        print("HOLD.")```

Hi,

I've added predict_next to methods.py and created a similar script to eval.py - but get the following error:

Traceback (most recent call last): File ".\predict.py", line 65, in main(eval_stock, window_size, modelname) File ".\predict.py", line 41, in main profit, = predict_next(agent, data, window_size) File "D:\Dev\StockPred\trading-bot-master\trading_bot\methods.py", line 112, in predict_next state = get_state(data, len(data)+1, window_size + 1) File "D:\Dev\StockPred\trading-bot-master\trading_bot\ops.py", line 26, in get_state res.append(sigmoid(block[i + 1] - block[i])) IndexError: list index out of range

Any suggestions?

Thanks in advance, great project! predict.zip

• apologies, I'm not well-versed in Python

Hey, I'll have to look that up in the next days, but yes I had the same error. I think as a quick fix you could add sth along the lines of

ops.py

def get_state(data, t, n_days):
    """Returns an n-day state representation ending at time t
    """
    #blocks = []
    #for feature in datan.columns:
    #feature = "Close"
    #data = list(datan[feature])
    if len(data) == 0:
        raise Exception("DATA IS ZERO!!! CHECK YFINANCE OUTPUT")
    d = t - n_days - 1
    block = []
    if d >= 0:
        block = data[d: t + 1] 
    else: 
        block = data[0:d] # pad with t0
    res = []
    for i in range(n_days - 1):
        x = sigmoid(block[i + 1] - block[i]) # x is number
        res.append(x)
    return np.array([res])
