I am of course talking about Portfolio API as with that you can actual create useful applications.

1 / second is how the stock exchanges works, so creating application that would have slower frequency would not be in sync the actual action frequency - intra-day or not.

so if I do something that's requests data once a second, what would be maximum amount of stocks that this kind of application use? less means less useful analysis.

1 / second seems excessive, and will probably be disallowed, especially if you plan on doing this across thousands of stocks.

Are you talking about the PortfolioAPI, or the iGoogle gadget dataAPI?

Hello,

Just wondering are there any usage amount limits of using this API?

This API just calls for retrieving data once a second for thousands of stocks (=max 200/portfolio) even though data is intra-day. Applications using this API has to work on-demand and/or retrieve data once a second.

Is that much of usage allowed? - better ask this before I start coding
