Owen,
There are 3 different things here [with the respective AFL solutions]:
When a COND is true for many concecutive bars, we may ask
a. To remember the value of an array from the last bar the COND was
true, solved through Valuewhen(COND,array) or the equivalent
AMA(array,COND)
b. To remember the value of an array from the first bar the COND was
true, solved through Valuewhen(COND AND Ref(COND,-1)==0,array) or the
equivalent AMA(array, COND AND Ref(COND,-1)==0)
c. To remember the value of an array exclusively from the [confirmed]
last bar the COND was true, solved through
Valuewhen(COND==0 AND Ref(COND,-1),Ref(array,-1)) or the equivalent
AMA(Ref(array,-1), COND==0 AND Ref(COND,-1))
The choice depends on the question.
