API Getting Started Using Data

Hi everyone,

I want to use my own data so I tried fetch_csv code example here with the same data provided with this example, and I saved the same data on dropbox. however, I got the following error:

Something went wrong. Sorry for the inconvenience. Try using the
built-in debugger to analyze your code. If you would like help, send
us an email.

Exception: Error parsing remote CSV data. There was a
runtime error on line 7.

(line 7 is where date_format = '%m/%d/%y') at)

Could you help me figure out where went wrong?

Also does fetch_csv only accept dateformat as "%m/%d/%y"? how about "%Y/%m/%d"?

Thanks a lot

Here is the code and dropbox link:

def initialize(context):  
    # fetch data from a CSV file somewhere on the web.  
    # Note that one of the columns must be named 'symbol' for  
    # the data to be matched to the stock symbol  
    fetch_csv('https://www.dropbox.com/s/ef3aqzueaypdecq/dataTest.csv?dl=0',  
               date_column = 'Settlement Date',  
               date_format = '%m/%d/%y')  
    context.stock = symbol('NFLX')  
def handle_data(context, data):  
    if 'Days To Cover' in data[context.stock]:  
        record(Short_Interest = data[context.stock]['Days To Cover'])

I got it now, the problem is still about the public url. dropbox and google drive does not provide public url, but copy does

If you're interested in hosting your .csv file on Dropbox or Google Drive, check out the help docs for instructions on how to make the URL public!
