Data problem

Every time when I start QuantShare ALUM (in example) starts downloading wrong values (from where?)
When I delete the wrong data and download it manually with the right downloader the values are OK.

Next time when I start QS I have the wrong values again?

Where does QS take these wrong values from?

Best Answer

This is because you have "Download -> Auto-Download Quotes" enabled and the auto-downloader gets data (when chart is loaded after app starts) from another downloader (Probably Historical Stock Market Data item).

I will go crazy!

Because there where some "runaways" in my data i decided to download all ETF again with option "remove old data".
start end end dates: from 01.01.1900 to Today

After downloading i have data starting in april 2011. (despite of that i have had data from years before....) Where have they been gone?
And where did i download it earlier?

It seems that one should take into consideration that i will last months to learn QS :-(

Only a few data after downloading all again:

If "Last symbol date" is checked then "From" date will not be used. Make sure it is unchecked.

I found the problem.
It is because the data provider uses a default start date (2010) if the provided date is far (1900).

Change 1900 to 2000.
