As part of the redesign of the market price page, I re-engineered the underlying algorithm and made it more sophisticated. So instead of simply taking the last prices into account as before, a more complex calculation now takes place including the use of weighted averages and better outlier detectors. The market prices should be more accurate now and that is the reason for your jump upwards. 
Feel free to take a closer look at the market prices and let me know how good you think they are. I’m happy about any feedback and improvement ideas.
