Metatrader5 - Python 集成 - symbol_total() 返回无

Question

I'm trying to get the number of symbols of metatrader5 and I'm getting an error

TypeError: '>' not supported between instances of 'NoneType' and 'int'

Link to the documentation: https://www.mql5.com/en/docs/integration/python_metatrader5/mt5symbolstotal_py

code:

import MetaTrader5 as mt5
print("MetaTrader5 package author: ",mt5.__author__)
print("MetaTrader5 package version: ",mt5.__version__)

if not mt5.initialize():
    print("initialize() failed, error code =",mt5.last_error())
    quit()

symbols=mt5.symbols_total()
if symbols>0:
    print("Total symbols =",symbols)
else:
    print("symbols not found") 
mt5.shutdown()

The problem is that the function is returning NoneType instead of a number. Why it's returning a NoneType? How can i get the list of Symbols/Stocks? Any clue?

I had the same problem too. If you are currently using a downloaded MT5 terminal from your broker, you can try using the official MT5 terminal instead. That seemed to have fixed my issue. Don't forget to specify the path to the correct MT5 terminal.exe afterwards within the initialization function initialize(path=...) .

As to why this was causing an issue, I'm unsure myself. I happened across this post and it mentioned that there may have been modifications made by brokers.

Anyway, hope this works for you too!

To connect to your broker's server afterwards, within the MT5 terminal under Navigator->Accounts (Right Click)->Open an account->Search for your broker and enter your credentials.
