Re: Website with practice examples

Something like advent of code might be more like what you're looking for, it's not language specific but the problems are fun and it's good practice.

Re: Rounding in select statement

I would define round:{(floor 0.5+y*i)%i:10 xexp x} and then you can do select time, sym, round[1]price from trade. As a bonus, this works with negative numbers too, round[-3; 12345.678] is 12000.

Each is an iterator/adverb - what that line does is applies pub to each item of 'til count subs', not applying pub to 'each til count subs'.
