Description:
  Hi, I'm trying to get daily closing prices of bunch of fx rates via Python.
  However, it doesn't take the starting date and the end date correctly.
da='2015-10-01' a= '2017-12-31'
ccy=['EUR=','EURTRY=','EURAUD=','EURCAD=','EURCHF=','EURGBP=','EURHKD=','EURJPY=','EURKRW=R','EURRUB=','EURSGD=','EURCNY=']
  fx=ek.get_timeseries(ccy,fields=['CLOSE'], start_date =da, end_date = a,
  interval='daily') 
I tried also to use another funciton but I don't know the
  correct field, can you please help me out? 
fx2=ek.get_data(ccy ,["TR.BID.date","TR.BID"],
  {"Sdate":da,'EDate': a,})[0] 
Thank you in advance
