注意

该函数类似于SymbolSelect

例如:

import MetaTrader5 as mt5
import pandas as pd
# 显示有关MetaTrader 5程序包的数据
print("MetaTrader5 package author: ",mt5.__author__)
print("MetaTrader5 package version: ",mt5.__version__)
print()
# 建立与MetaTrader 5程序端的连接
if not mt5.initialize(login=25115284, server="MetaQuotes-Demo",password="4zatlbqx"):
    print("initialize() failed, error code =",mt5.last_error())
    quit()
 
# 尝试在市场报价中启用显示EURCAD
selected=mt5.symbol_select("EURCAD",True)
if not selected:
    print("Failed to select EURCAD, error code =",mt5.last_error())
其他
    symbol_info=mt5.symbol_info("EURCAD")
    print(symbol_info)
    print("EURCAD: currency_base =",symbol_info.currency_base,"  currency_profit =",symbol_info.currency_profit,"  currency_margin =",symbol_info.currency_margin)
    print()
 
    # get symbol properties in the form of a dictionary
    print("Show symbol_info()._asdict():")
    symbol_info_dict = symbol_info._asdict()
    for prop in symbol_info_dict:
        print("  {}={}".format(prop, symbol_info_dict[prop]))
    print()
 
   # 将词典转换为DataFrame和print
    df=pd.DataFrame(list(symbol_info_dict.items()),columns=['property','value'])
    print("symbol_info_dict() as dataframe:")
    print(df)
 
# 断开与MetaTrader 5程序端的连接
mt5.shutdown()
