if not mt5.initialize():
print("initialize() failed, error code =",mt5.last_error())
quit()
# 尝试在市场报价中启用显示EURJPY交易品种
selected=mt5.symbol_select("EURJPY",True)
if not selected:
print("Failed to select EURJPY")
mt5.shutdown()
quit()
# 显示EURJPY交易品种属性
symbol_info=mt5.symbol_info("EURJPY")
if symbol_info!=None:
# display the terminal data 'as is'
print(symbol_info)
print("EURJPY: spread =",symbol_info.spread," digits =",symbol_info.digits)
# display symbol properties as a list
print("Show symbol_info(\"EURJPY\")._asdict():")
symbol_info_dict = mt5.symbol_info("EURJPY")._asdict()
for prop in symbol_info_dict:
print(" {}={}".format(prop, symbol_info_dict[prop]))
# 断开与MetaTrader 5程序端的连接
mt5.shutdown()
