||
print("MetaTrader5 package author: ",mt5.__author__)
|
||
print("MetaTrader5 package version: ",mt5.__version__)
|
||
print()
|
||
# establish connection to the MetaTrader 5 terminal
|
||
if not mt5.initialize(login=25115284, server="MetaQuotes-Demo",password="4zatlbqx"):
|
||
print("initialize() failed, error code =",mt5.last_error())
|
||
quit()
|
||
|
||
# attempt to enable the display of the EURCAD in MarketWatch
|
||
selected=mt5.symbol_select("EURCAD",True)
|
||
if not selected:
|
||
print("Failed to select EURCAD, error code =",mt5.last_error())
|
||
else:
|
||
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()
|
||
|
||
# convert the dictionary into DataFrame and print
|
||
df=pd.DataFrame(list(symbol_info_dict.items()),columns=['property','value'])
|
||
print("symbol_info_dict() as dataframe:")
|
||
print(df)
|
||
|
||
# shut down connection to the MetaTrader 5 terminal
