Hi Thorsten,
This time 2:00 – 24:00 will work for most brokers but you should check if it is set to yours.
You should of course backtest any EA on your brokers data before trading it and that may show up if there is an issue with your brokers time. I am sure Petko will confirm but I would consider the times above to be adjusted to UTC +2 with daylight savings, so quickest way to adjust if necessary would just be to clarify what your brokers time is set too.
