[BUG] Unsupported filling type using documentation examples

[ViktorPython]

Hello, 

I know this topic has been addressed before but I cannot find a scenario where it also happens using documentation available examples.

Using a freshly installed MT5=5 build 2489, the most recent library for python MT5=5.0.33 and the example from: https://www.mql5.com/en/docs/integration/python_metatrader5/mt5ordersend_py 

import MetaTrader5 as mt5
# display data on the MetaTrader 5 package
print("MetaTrader5 package author: ",mt5.__author__)
print("MetaTrader5 package version: ",mt5.__version__)
 
# establish connection to MetaTrader 5 terminal
mt5.initialize(login=<this has my login number>, server="XM.COM-MT5",password="<this has my pass>")
 
# get account currency
account_currency=mt5.account_info().currency
print("Account сurrency:",account_currency)
 
# prepare the request structure
symbol="USDJPY"
symbol_info = mt5.symbol_info(symbol)
if symbol_info is None:
    print(symbol, "not found, can not call order_check()")
    mt5.shutdown()
    quit()
 
# if the symbol is unavailable in MarketWatch, add it
if not symbol_info.visible:
    print(symbol, "is not visible, trying to switch on")
    if not mt5.symbol_select(symbol,True):
        print("symbol_select({}}) failed, exit",symbol)
        mt5.shutdown()
        quit()
 
# prepare the request
point=mt5.symbol_info(symbol).point
request = {
    "action": mt5.TRADE_ACTION_DEAL,
    "symbol": symbol,
    "volume": 1.0,
    "type": mt5.ORDER_TYPE_BUY,
    "price": mt5.symbol_info_tick(symbol).ask,
    "sl": mt5.symbol_info_tick(symbol).ask-100*point,
    "tp": mt5.symbol_info_tick(symbol).ask+100*point,
    "deviation": 10,
    "magic": 234000,
    "comment": "python script",
    "type_time": mt5.ORDER_TIME_GTC,
#    "type_filling": mt5.ORDER_FILLING_RETURN,
}
 
# perform the check and display the result 'as is'
result = mt5.order_check(request)
print(result);
# request the result as a dictionary and display it element by element
result_dict=result._asdict()
for field in result_dict.keys():
    print("   {}={}".format(field,result_dict[field]))
    # if this is a trading request structure, display it element by element as well
    if field=="request":
        traderequest_dict=result_dict[field]._asdict()
        for tradereq_filed in traderequest_dict:
            print("       traderequest: {}={}".format(tradereq_filed,traderequest_dict[tradereq_filed]))
 
# shut down connection to the MetaTrader 5 terminal
mt5.shutdown()

The result is:

MetaTrader5 package author:  MetaQuotes Software Corp.
MetaTrader5 package version:  5.0.33
Account сurrency: EUR
OrderCheckResult(retcode=10030, balance=0.0, equity=0.0, profit=0.0, margin=0.0, margin_free=0.0, margin_level=0.0, comment='Unsupported filling mode', request=TradeRequest(action=1, magic=234000, order=0, symbol='USDJPY', volume=1.0, price=107.155, stoplimit=0.0, sl=107.055, tp=107.255, deviation=10, type=0, type_filling=0, type_time=0, expiration=0, comment='python script', position=0, position_by=0))

       traderequest: action=1
       traderequest: magic=234000
       traderequest: order=0
       traderequest: symbol=USDJPY
       traderequest: volume=1.0
       traderequest: price=107.155
       traderequest: stoplimit=0.0
       traderequest: sl=107.055
       traderequest: tp=107.255
       traderequest: deviation=10
       traderequest: type=0
       traderequest: type_filling=0
       traderequest: type_time=0
       traderequest: expiration=0
       traderequest: comment=python script
       traderequest: position=0
       traderequest: position_by=0
True

I find it very strange and makes me second guess the documentation or I've found a bug. Though to be honest I'm hoping I made a beginners mistake. This issue occurs for all combinations of type_filling,type_time,type and action. I know this as each represents an integer and by abusing loops I've tested all possible combinations, none worked. 

Some additional information:

• Algo trading is on
• No exceptions are listed
• The following is the result of mt5.account_info()

AccountInfo(login=XXXXXX, trade_mode=0, leverage=30, limit_orders=200, margin_so_mode=0, trade_allowed=True, trade_expert=True, margin_mode=2, currency_digits=2, fifo_close=False, balance=1001.61, credit=0.0, profit=0.0, equity=1001.61, margin=0.0, margin_free=1001.61, margin_level=0.0, margin_so_call=100.0, margin_so_so=50.0, margin_initial=0.0, margin_maintenance=0.0, assets=0.0, liabilities=0.0, commission_blocked=0.0, name='ViktorPython', server='XM.COM-MT5', currency='EUR', ...)

• And the result of mt5.terminal_info()

TerminalInfo(community_account=False, community_connection=False, connected=True, dlls_allowed=False, trade_allowed=True, tradeapi_disabled=False, email_enabled=False, ftp_enabled=False, notifications_enabled=False, mqid=False, build=2489, maxbars=100000, codepage=1252, ping_last=23347, community_balance=0.0, retransmission=0.10604453870625664, company='Trading Point Of Financial Instruments Ltd', name='XM MT5', language='Dutch', path='C:\\Program Files\\XM MT5', ...)

Please help!

Kind regards,

Viktor
