Hi ibne,

thank you, now it works better, less computing power needed.
The usetickcallback parameter kills a relative big M3.medium AWS instance, so it won't work on other smaller instances like T2.micro or similar, where Zorro is normally used for long term live trading.

By the way, alsoo the PIN recongition works fine, it was a failure on my configuration side. The log files really misleeded in this particular point.
