Yahoo Data Download "Database Corruption" and Inability to Download More Data

[Anagoge]

I setup a default data connection to Yahoo in NT7-64. I added a stock instrument mapping to the Nyse exchange and the ^GSPC symbol on Yahoo (S&P 500). I created a chart with the last 365 days of data. That showed fine. Then I changed the dataseries to 1000 days and the chart did not re-download the added data from Yahoo. I had to close and re-create a new chart to get it to load the full 1000 days of data. I did the same with a 20000 day chart.

Then, I closed and recreated another chart this time trying to show 25000 days of daily data (back a bit farther then Yahoo actually supplies). NT7 reported database corruption as attached. [It would be helpful if the text in this type of error message was copyable to the clipboard.]

To reproduce, delete the instrument historical data, load 20,000 days, close the chart and then try to load 25,000. Somehow, it corrupts the database when merging the new days into the database. I can reproduce at will.

Hello Anagoge,

Thank you for reporting. I was able to reproduce the corruption in the database as well when performing the same steps.

I will forward your findings to our Development department.
