problems with stock ticker

Hi,

I wanted to add a stock ticker for Apple. Therefore I added the following:

Alert name: Apple
name of stock: AAPL
Audio Flash at 11:00
Light language: YES

All I SEE is now a yellow light band moving from right to left (equivalent falling of stock even it raised in the last days ...)

All I HEAR is the sound of a cashier but no change of the stock ...

Am I doing something wrong?

thanks for answers

P.S. The ticker for the DAX is working correct. even I am not able to decide in the light language between AAPL and DAX ...
