Conditions are true or false.
AFL conditions are also true or false.
AFL conditions are equal to 1[true] or 0[false].
The value of a
Cond=...
array will be, for example,
...,1,0,0,1,0,0,1,1,0,...
If a condition is true *only once* the last 5 bars then the value
will be
1,0,0,0,0
or
0,1,0,0,0
or
0,0,1,0,0
or
0,0,0,1,0
or
0,0,0,0,1
There are many ways to express this fact in AFL.
Here is a short one
Cond=...
Last5bars=Sum(Cond,5)==1;
If the condition is true *at least once*, then
Cond=...
AnyoftheLast5bars=Sum(Cond,5)!=0;
