How to get multiple stock data from dropbox by Ka Ho Cheung

From Documentation, I find an example, which can get data from a csv file. I copy it and link to dropbox successfully.

The problem is that if I have multiple stocks and multiple csv files, I may need to create links from dropbox one by one. Now I have many stocks and I may need to copy those links one by one, I have too many files and it is not possible for me to manage them.

I would like to ask if there is a way to handle this process ?

Thank you very much.

Hi Ka Ho Cheung ,

Given that the files have the same structure, we can use the same custom data class. We can use a dictionary, keyed by the ticker, of links to the Dropbox data:

    def GetSource(self, config, date, isLiveMode):

        # Use a Dictionary for each file in Dropbox keyed by the ticker

        sources = {

            'MSFT': "https://www.dropbox.com/s/qjfem6mw5cpozdw/MSFT.csv?dl=1",

            'AAPL': "https://www.dropbox.com/s/ok4d5hzrkozt41l/AAPL.csv?dl=1"

            }

            

        return SubscriptionDataSource(sources[config.Symbol.Value], SubscriptionTransportMedium.RemoteFile);

Please find a working example in the attachment.

Dear Alexandre,

Thank you for your reply. I can see that you have 2 links

I would like to ask if there is a way to create a link to the folder first:

https://www.dropbox.com/s/ooooooooo

And then I can have:

I have do some research and find that there is apis for dropbox, but it is a little bit complicated for me. So I would like to ask for a simpler method. It is okay if there is no way to do it at this moment. Thank you very much.

Hi Ka Ho Cheung,

This is not currently possible. When sharing Dropbox files that are in the same folder, the parent directory is still different. For example, if we have sheet1.csv and sheet2.csv in the folder, after sharing them, the links will look like:

https://www.dropbox.com/s/wvkw8sdtsmxv01d/sheet1.csv?dl=1
https://www.dropbox.com/s/tki5hrnvkymoqlm/sheet2.csv?dl=1

It's also not possible to add onto the Dropbox folder URL to access the contents of the folder.

I suggest storing the files on GitHub instead. Accessing the files in a folder would then be possible.

Best,
Derek Melchin
