Why do the in-transfer values differ from the out-transfer values after the changeover of my custody account from Baader to Scalable?

In the Transaction Overview in your client area, you will see both the out-transfers from the Baader Account and the in-transfers to your Scalable Account. 

The number of units is the same. 

Possible differences in the Euro valuation are due to the different prices at different valuation times. The out-transfer is valued at the market price at the time of the booking out. Similarly, the in-transfer is valued at the market price at the time of the booking in. 

The difference between the two valuations therefore reflects the price development in the meantime.
