Until last week I was using stocknod.com to get daily historical prices including percent change. But for some reason the data there now stops at 9/26/16. Anyone have another source? Note: Even a dollars and cents daily change without a percent change figure would be helpful. Since each historical price site has its own idiosyncrasies, any and all suggestions people can come up with would be greatly appreciated.
Barchart looks like a good source, but I often like to look at a table rather than a chart. Barchart does have great table info for the last 5 days (or 5 weeks or 5 months, but not daily within that). Thanks.
yahoo... https://ca.finance.yahoo.com/q/hp?s=YHOO They give you the daily prices, put in excel and calculate the percent changes.
Thanks, that may help. I'm still hoping for a quick tool. Stocknod takes about 10 seconds; I hate it when things that worked no longer do.
you can plugin the yahoo api to python, that way it takes about a second per symbol to get a good chunk of daily data, make calculations on it and dump it to csv or have it loaded in memory and ready to work... this guy explains how to do it in a pretty straight fwd way. https://streamofconscientia.wordpress.com/2015/01/22/using-pandas-to-get-stock-data/
This gives you one year of historical data http://chartapi.finance.yahoo.com/instrument/1.0/AAPL/chartdata;type=quote;range=1y/csv
stdy, try this: https://tradefinder.net/#/main You can use TF to get all percentage changes (from last, from open, gaps, whatever) for each listed symbol. 20 years back, CSV format at the end, EOD updates, no real time however.
