Yes. But I am not sure how that creates the problem I am seeing.
Because when TestAFL.afl is processed, say for a =1, it simply results
in the following statement first being placed into memory:
FastMALength = 1;
then the main AFL is processed, and this should result in the
crossover trade being processed with the above variable assignment.
But instead of the above variable assignment, it instead is:
FastMALength = 5;
How and why does it skip from 1 to 5?
