Is there a limit to amount of symbols you can request at once? about yahoofinanceapi

Unfortunately the Yahoo API is not something that you can blindly relay on.
I mainly using historical API, but the failing reason should be similar.

I found out that there are symbols that keep failing more than others (for instance PPC, MU).
By more I mean: many bad requests (400) or success (200) with empty data (nulls).
I have no idea why, but maybe those requests are collected from different endpoints than others.

Moreover I observe that when queried those tickers for 2 to 3 years of data can failed persistently while passing against small amount of data (like 30days).

That's lead me to conclusion that if you ask for smaller data then the better are chances to retrieve valid response.

@delvier thanks for the information, do you happen to know if there is a rate limit for making calls to the Yahoo API?

[pljanot]

@dotnetshadow I don't know to be honest. But I think it's quite high, I could not reach any limits making thousand of requests per minute during intensive testing.

YahooFinanceApi does not impose any limitations on the number of symbols requested. I was able to download 1000 symbols. I noticed that larger number of symbols is limited by URI length.
