Is it possible to load a certain price going back to a specific timestamp, or a series of x bars from this time on? In Mql the function to copy/load prices can be overloaded, instead of bars back from current time you can use timestamp to timestamp, or number of bars from a timestamp. Can't find something like this within Zorro?

*i want/need to go back very far, (many years) like loading the price series from the 20.01.2010 0:00 till 23:59 even though the current bar is just now.

No, but that should be easy to write. Use ymd(wdate(i)) and increase i until you found the timestamp.
