Matlab access historical Data
Hello, I'm a retail trader but my trading style is heavily statistical. I wrote some code in MATLAB to grab historical data from Yahoo Finance for about 1000 stocks and run my statistical analysis on a daily basis. Lately however, about half the symbols queried return no data. It is inconsistent but in general significant amounts of data is missing when I query more than 250 symbols or so. Does the Yahoo Finance server have a limit on the amount of symbols that can be queried in a given amount of time from an IP address? If so, does Yahoo Finance plan on adding premium access to historical data to paid memberships to guarantee unlimited data access?
Thanks in advance,
