Hi There. I'm trying to run the following using pycharm IDE (python 2.7). I however get a "400 Ba...

...d Request" error as per below. This error does not always occur, sometimes the exact same script runs fine. Please advise.

My Script:

df, err = ek.get_data(000001.SZ,000002.SZ,000030.KS,000039.SZ,000050.SZ,
TR.PriceClose.calcdate;
TR.EPSActValue(Period=FY - 3);
TR.EPSActValue(Period=FY - 2);
TR.EPSActValue(Period=FY - 1);
TR.EPSActValue(Period=FY0);
TR.EPSMean(Period=FY1);
TR.EPSMean(Period=FY2);
TR.EPSMean(Period=FY3);
TR.NumberOfAnalysts(Period=FY - 3);
TR.NumberOfAnalysts(Period=FY - 2);
TR.NumberOfAnalysts(Period=FY - 1);
TR.NumberOfAnalysts(Period=FY0);
TR.NumberOfAnalysts(Period=FY1);
TR.NumberOfAnalysts(Period=FY2);
TR.NumberOfAnalysts(Period=FY3);
TR.EPSMean(Period=FY - 3).periodenddate;
TR.EPSMean(Period=FY - 2).periodenddate;
TR.EPSMean(Period=FY - 1).periodenddate;
TR.EPSMean(Period=FY0).periodenddate;
TR.EPSMean(Period=FY1).periodenddate;
TR.EPSMean(Period=FY2).periodenddate;
TR.EPSMean(Period=FY3).periodenddate
,SDate=2017-01-01,EDate=2017-03-31,Frq=M)

Error I get:

I'm afraid the method you're executing doesn't make sense to me on more than one level.
The request example you provided has so many syntax errors, I don't see how it can possibly ever run fine. I have to assume that somehow the text must have been altered in transfer between IDE and your post here? Otherwise you'd be getting syntax errors instead of HTTP 400.
Semantically why do you want to mix the last business day of the month between January and March 2017 (provided by TR.PriceClose.calcdate with {'SDate':'2017-01-01','EDate':'2017-03-31','Frq':'M'} parameters) with EPS estimates for the previous and the next 3 years? But assuming for whatever reason this is indeed what you want to retrieve, the correct syntax is:

df, err = ek.get_data(['000001.SZ','000002.SZ','000030.KS','000039.SZ','000050.SZ'], ['TR.PriceClose.calcdate', 'TR.EPSActValue(Period=FY-3)', 'TR.EPSActValue(Period=FY-2)', 'TR.EPSActValue(Period=FY-1)', 'TR.EPSActValue(Period=FY0)', 'TR.EPSMean(Period=FY1); TR.EPSMean(Period=FY2)', 'TR.EPSMean(Period=FY3)', 'TR.NumberOfAnalysts(Period=FY-3)', 'TR.NumberOfAnalysts(Period=FY-2)', 'TR.NumberOfAnalysts(Period=FY-1)', 'TR.NumberOfAnalysts(Period=FY0)', 'TR.NumberOfAnalysts(Period=FY1)', 'TR.NumberOfAnalysts(Period=FY2)', 'TR.NumberOfAnalysts(Period=FY3)', 'TR.EPSMean(Period=FY-3).periodenddate', 'TR.EPSMean(Period=FY-2).periodenddate', 'TR.EPSMean(Period=FY-1).periodenddate', 'TR.EPSMean(Period=FY0).periodenddate', 'TR.EPSMean(Period=FY1).periodenddate', 'TR.EPSMean(Period=FY2).periodenddate', 'TR.EPSMean(Period=FY3).periodenddate'],{'SDate':'2017-01-01','EDate':'2017-03-31','Frq':'M'})

I noticed in your example you have white spaces in some of the field level parameters, e.g. there are two spaces in TR.NumberOfAnalysts(Period=FY - 3). Not sure of you had them in your script, but these spaces will certainly result in HTTP 400 error.
