Cool
So, maybe better to use
minticks={TODAY:unixtime:-P50Y}000 (one-time use)
minticks={TODAY:unixtime:-P6M}000
maxticks={TODAY:unixtime}000
Haven’t tested it yet, but I think the macro provides the timestamp in seconds, not milliseconds, hence the three zeros at the end.
EDIT: Now I’ve tested it, works like a charm
