[Why
not just specify a start date? Mostly just because client views
(layout maths) should not need to be concerned with what the
source/resulting time period is; they should just be able to say how
much data they need (or will fit) in the easiest way possible and the
backend figures out the rest.]<br></blockquote><div><br>On second thought, specifying a start date would still be an "easiest way possible." This could be used to track individual investments, say, by displaying all the price history starting from a user's initial investment. Then further investments could be marked by a triangle showing time/performance stats or whatever.<br>
