Hi.
I noticed that Drägerwerk, A German stock in one of my systems displays €50.60 price in P123 but in reality on exchange it is €62.90.
I don't know if this is an outlier error or something. Also I don't know if this also distorts the calculated multiples etc. The chart progression looks fine but with wrong price range.
Does someone have experiences with such issues? Do I have to worry that such errors also distort my general backtests?
Kind regards, Tony
