I am working on a project for class and am getting this message when trying to pull data from Yahoo. When I run a script that just pulls the data it works, but when I try pulling the data of two symbols I get this error

Is there a way to have matlab ignore this error and continue the script if it can't find the data. Right now it halts running with this red error message

The note on yahoo.fetch says: "Retrieving historical data for multiple securities at one time is not supported for Yahoo. You can fetch historical data for only a single security at a time."

You should build a loop assigning the result to a cell array or structure.

I have the Yahoo fetch in a loop but I still get this. It seems to only happen after hours perhaps the system is down or you can only grab during market hours?
