like, you could use Param statements to make the MA period and each threshold
adjustable without changing the
code.

that many operations work on entire arrays at once. This means that in many
cases, you don't need any looping or other bar-by-bar constructs. For example,
BarsAboveMA is an array, where each bar's data is the number of bars since Close
was above the MA, and that entire array was built without looping, in one
line of code.

>Can
someone point me in the right direction on developing an indicator that
can highlight sections of a chart that's above an MA?I'm also hoping
to be able to set criteria of highlighting secitions of the chart that are
X number of days above the MA, and that X number can vary or even be
different numbers with different numbers being highlighted as different
colours. eg. 10days=yellow, 8days=purple, etc.I'm looking into
AFL, and it looks like I would need to do it by using a starting reference
time which crossed MA and then looping forwards or backwards in time until
the next time it crosses. This would be the obvious solution of doing
this.Any assistance would be greatly
appreciated.Albert
