Sorry. I didn't copy all the code since the example already had the
following which you need to add at the top of your code, at least
above where ai is used:
bi = BarIndex();
ai = bi - bi[0];
In AFL all the variables have to be declared and assigned some
initial value before they are used. Since ai is used inside a
statement it needed to be declared first. The above code declares ai
and assigns it to the value of bi - bi[0];
I used ExRem in my example but Ara said he used Flip instead. Play
with both and see what differences there are.
