Pandas TA strategy method goes into infinite loop: Windows Freeze Support Error

See original GitHub issue

@twopirllc I was trying to run the below code on a dataframe

df.ta.strategy("Momentum")
print(df)

It goes into infinite loop and consumes all CPU on my windows 10 laptop. Then I need to kill all VSCodium and python exes. Could you please help?

You can close this issue if you do not want to investigate further, as I have got the solution which is as below: source code


import yfinance as yf
import pandas_ta as ta


def test():
    sbin = yf.Ticker("SBIN.NS")
    df = sbin.history(period="3d", interval="15m")
    df.ta.strategy("Momentum", verbose=True)
    print(df)

if __name__ == '__main__':
    test()

pwsh.exe console output

(venv) PS D:\trading\0sas_algo> cat .\crash.py
import yfinance as yf
import pandas_ta as ta


def test():
    sbin = yf.Ticker("SBIN.NS")
    df = sbin.history(period="3d", interval="15m")
    df.ta.strategy("Momentum", verbose=True)
    print(df)

if __name__ == '__main__':
    test()

Again tried with python 3.9.1 and still getting same issue. Control + C is also not working. Anyways this is not high priority for me. I will concentrate more on the other stuff. Will continue there. Let me know if you are able to reproduce this issue at your end. I can try to uploaded a video if I get time.
