What's the rate limit?

[sbr2567]

I've been fetching stocks in a for loop. I notice after about 110 stocks, the fetch no longer is returning any data whatsoever. I am catching any errors and have avoided all errors, but when this occurs there is no error. It's simply not supplying me data. So i'm assuming this is because i'm meeting yahoo-finance's rate limit.

What is the rate limit for this package?
