I am trying to connect to Yahoo Finance with the Datafeed Toolbox, but I obtain the following error:
>> c = yahoo
Error:
Error using yahoo
Unable to connect or retrieve data from given URL.
>> fetch(yConnect,’AAPL’) % generates an error
>> fetch(yahoo,'%5EGSPC',{'Last'}) % either returns empty or generates an error
Error using urlreadwrite (line 98)

For those who have active accounts with TD Ameritrade / Thinkorswim, I have a solution to this problem. This involves use of a Matlab toolbox I developed so it can be considered a solicitation. Therefore, if you want to know more then just send me an email and we can discuss through other channels.

I implemented the fix (I am using R2017a), and it does not work for historical data. It only works for current data:
>> fetch(yahoo,'IBM')
ans =
struct with fields:
Symbol: {'IBM'}
Last: 152.6400
Date: 736837
Time: 0.6681
Change: 0.6600
Open: 152.1000
High: 152.8400
Low: 151.6000
Volume: 3302539
But when I try for historical data I get an error:
>> fetch(yahoo,'IBM','02/01/2017','03/20/2017')
Error using yahoo/fetch (line 387)
Unable to return historical data for given security.

I hope your fix work and can be shared to the community in the File Exchange. Not historical but is something
