Hi all,
I am getting a strange error on a what i think is a simple for loop.
The alphavantage function is located-
I want the loop, to loop over symbols and create a seperate table for each symbol.
My attempt is below. The function buy itself works as expected.
Best,
Andrew
>> symbols = {'^GSPC', 'DAX', '^N225', 'GLD', 'QQQ'};
for k = 1:length(symbols)
symbols{k} = table2timetable(F_Alphavantage('time_series_daily_adjusted', 'symbol',...
symbols{k}, 'outputsize', 'full'));
end
disp(head(data{1}))
Subscripting a table using linear indexing (one subscript) or multidimensional indexing (three or more
subscripts) is not supported. Use a row subscript and a variable subscript.

The error seems to be in the disp, not in the rest of the code. Can you copy all the red text that is showing up?

Andrew
symbols = {'^GSPC', 'DAX', '^N225', 'GLD', 'QQQ'};
for i = 1:length(symbols)
data{i} = table2timetable(F_Alphavantage('time_series_daily_adjusted', 'symbol',...
symbols{i}, 'outputsize', 'full'));
end
