获取交易账户信息

account_info 函数可获取当前交易账户的所有信息。

namedtuple account_info()

该函数以命名元组 (namedtuple) 的结构体返回信息。如果出现错误，则结果为 None。

使用此函数，你可以使用一个调用来获取在 MQL5 中由 AccountInfoInteger、 AccountInfoDouble 和 AccountInfoString 提供的所有信息，包括支持特性的所有变体。元组中字段的名称对应于没有 "ACCOUNT_" 前缀的枚举元素的名称，简化为小写。

本书中包含以下 MQL5/Scripts/MQL5Book/Python/accountinfo.py 脚本。

import MetaTrader5 as mt5

# let's establish a connection to the MetaTrader 5 terminal
if not mt5.initialize():
   print("initialize() failed, error code =", mt5.last_error())
   quit()

account_info = mt5.account_info()
if account_info != None:
   # display trading account data as is
   print(account_info)
   # display data about the trading account in the form of a dictionary
   print("Show account_info()._asdict():")
   account_info_dict = mt5.account_info()._asdict()
   for prop in account_info_dict:
      print("  {}={}".format(prop, account_info_dict[prop]))

# complete the connection to the MetaTrader 5 terminal
mt5.shutdown()

结果应该是这样的。

AccountInfo(login=25115284, trade_mode=0, leverage=100, limit_orders=200, margin_so_mode=0, ...
