Yahoo Historical Data - Did they change the URL recently?

[HobbyTrading]

This might be old news but I just got an email from yahoo saying Verizon has purchased many of their online services and the terms of service have changed.

And in the sense of true customer service, did they not include an overview of the changes. Yahoo only included a link to the webpage where the T&C's can be found.

True, but the bottom line is that they were giving the data for free without any advertising to support it. Why do it? What do they gain by hosting data for nothing? I wish they would give away the data for free, but it can't be expected.

I agree with what you are saying but lets say you were an end user of the yahoo finance website and follow their expected typical use cases. Simply viewing the site with your browser is now extremely slow. They are screwing things up even among their intended end users.

It's a company that had a ton of potential in the 90s, but its management did not live up to the optimism. Not sure why Verizon bought them. Pulling EOD historical data was the only thing I used Yahoo for. I use Finviz whenever I want to pull up a quick chart.

There seems to be a general crackdown on financial data scraping. It used to possible to scrape free historical currency data from oanda until just recently.

I never understood why financial exchanges want to tightly regulate their real-time data distribution and historical data redistribution...is it nothing more than they just want to make more money on selling the data?

All of these ISPs and triple play companies here in the USA have horrible customer service as well as slow and messed up websites. If you thought it was not possible for yahoo to get any worse well....yeah it is possible lol.

yes. i got it too. about a week ago

What do you mean by "15 seconds time restrictions between requests"?
If you are requesting live market data you can do so for 100 tickers in parallel, at the same time (unless your account size is large, or paid for a larger quantity of tickers, then you can do more). If you are asking for historical data you can request 60 items per 10 minute period, is what their documentation states. However, lately some people reported that they were able to download more than that limitation.

i was referring to limitation on historical data requests,not requests for real time data

------------
Pacing Violations
All of the API technologies support historical data requests. However, requesting the same historical data in a short period of time can cause extra load on the backend and subsequently cause pacing violations. The error code and message that indicates a pacing violation is:

162 - Historical Market Data Service error message: Historical data request pacing violation

The following conditions can cause a pacing violation:

• Making identical historical data requests within 15 seconds;
• Making six or more historical data requests for the same Contract, Exchange and Tick Type within two seconds.
