I have developed and tested with the this API last week. Today I am noticing I am not receiving any results even from the sample query.
https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.historicaldata%20where%20symbol%20%3D%20%22YHOO%22%20and%20startDate%20%3D%20%222009-09-11%22%20and%20endDate%20%3D%20%222010-03-10%22&diagnostics=true&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys
Anyone else experiencing this?
