And that’s why the Yahoo! finance data is free…
Earlier this month Yahoo!’s finance data feed application programming interface (or API) was changed. This made thousands of Excel spreadsheets pulling stock prices or fundamental data from Yahoo! fall over.
Our software can also pull data from Yahoo! – notably prices, earnings and ex-dividend dates.
Fortunately, when we built the software we hedged on data sources and included redundancy: there are several feeds to pick from, both free and paid. So users are covered on that count.
However, the earnings and ex-dividend dates are tougher to come by and pipe into ArbMaker elegantly. We are seeing what we can do and will update here accordingly.
