It depends where you get your data. IF you use AmiQuote to get EOD data from Yahoo just download the historical quotes again. If you want to back your data up find the database on your hard drive and just copy the database into a backup folder. If you are talking about intraday data that can't be retrieved again then back it up as defined above. And do it within the period that you can get the data. In other words if your supplier has a month of back fill then back your data up monthly.
Don't just delete your database and start over. If you do that you will lose all your layouts and it is a real pain in the butt to recreate them. If you want to delete your database save your layout files first. Barry --- In [email protected], "aussiejhv" <[EMAIL PROTECTED]> wrote: > > I have recently started to use Amibroker.
