Gr8. On prices no they should be the same. You would need to let me know exactly what you are looking at for me to understand. Keep in mind in addition to market level Zorro is showing traded level, stops, trails etc. These are all dif to the current market level.

On the GUI side Zorro is um-ashamedly minimalistic. They are leaving the GUI up to other packages that exist like you say MT4 (yuck!). Actually what I am currently personally working on is using R to visualize/chart the Zorro data files in a better way. I've made good progress but it is summer time - so project only moves on rainy days wink

FYI I'll be offline this weekend but back at it Monday.
