NameError: name 'MT5Initialize' is not defined - Python integration?

[fxchampion888]

Greetings,

Hope this is is correct section to post. I am trying to get the Python integration to work with Metatrader 5, however I am getting this error when execute the pythonscript-

NameError: name 'MT5Initialize' is not defined

Have made exactly like the tutorial fond here - https://www.mql5.com/en/docs/integration/python_metatrader5

Even tried to add path to MetaTrader5 like this - 

# connect to MetaTrader 5
MT5Initialize(path="C:\\Program Files\\MetaTrader 5\\terminal64.exe")

Anyone who can help me out? I am jumping up and down of excitement when I found the Python pip package...

MetaTrader 5 Python User Group - how to use Python in Metatrader

Since version 5.0.15, the Python library works in a new format that is not compatible with the old format and requires the latest beta terminal.

We’ll publish updated documentation and examples soon.

Thanks Sergey. 

Tried to find from the package folder. Found the new function naming. :)

mt5.symbol_select(symbol)

time.sleep(1)
p = mt5.symbol_info_tick(symbol)
prev_price = p.ask

while True:
    p = mt5.symbol_info_tick(symbol)
    print(p.bid,'/',p.ask)
    
    if p.ask > prev_price and buy_price == 0:
            print("Buy ", p.ask)
            r = mt5.Buy(symbol, 0.01)
            if r.retcode == mt5.TRADE_RETCODE_DONE:
                buy_price = p.ask;
    elif buy_price > 0 and p.ask + dev < buy_price:
        print("Buy(close) ", p.bid)
        mt5.Close(symbol)
        buy_price = 0

    prev_price = p.ask
    time.sleep(1)

Thanks

to address the "IPC recv failed" I install the beta version of metatrader5:

• beta MT5 is downloaded via Help -> Check beta version
• python library:

it worked for me

NameError: name 'MT5Initialize' is not defined

Python knows the purposes of certain names (ex. built-in functions ). Other names are defined within the program (ex. variables). If Python encounters a name that it doesn't recognize, you'll probably get NameError: global name 'xx' is not defined error. In most cases, this error is triggered when Python sees a variable name (Global or Local) and doesn't know what it's for. These errors can happen if you forget to initialize a variable , if you misspell a variable, or if you misspell a reserved word such as "True". Before you use the global variable in your function for reading, it must be first initialized somewhere: either outside of the function or inside it.
