german stock exchange, etr vs fra

i still can't understand why there is a price discrepancancy.  there isn't. it's the same stock and price differences between such major exchanges will always be minimal. i think you simply haven't paid attention to the date range. it seems google finance only has data for fra:bmw reaching back to 2011, so if you try to look at the development of your investment since 2009, you're not getting comparable data.
