Update: When I set Lookback to 0 I get the correct closePrice(); But just one line. What I need is an export of n prices.

Does it have to do with my historical data source? I am using ICMarkets for it and I discovered that the the price which can be downloaded (UpdateDays = -1;) feels like about a day older. That seems to me the cause.

But if so, how does Zorro say that f.I. priceClose(24hago) is the priceClose(now)?

This is for instance supposed to be a closePrice(0) but it's from about closePrice(24hago):


I am irritated.
