I should check - am I reinventing the wheel here? My basic aim is to
be able to find new highs without limiting the search to a certain
period (e.g. if I search for prices crossing the prior 100 period
high, this will miss the break of a 110 day high, and so on). Is this
built into a function? or has someone already written the code for
this?
I've looked but can't find anything.
Thanks
Chris
