I’m looking for a way to reset mins, or scan by group.

For example, I want to query, “What is the running min for column low, since column cond was last true” ?
mins doesn't work as it returns a running min of the entire list
mmins doesn't work as the size of the window changes from group to group
for example:

t:([]low:30?20; cond:30?01b)

Any suggestions on how I could update a column C that stores the moving low as long as cond=0?

And that moving low resets everytime cond=1?

Thanks
