Richard, The code set started from an article someone read from the WSJ.
Related to "...gain the skills necessary to program in AFL..."; when you figure that out, please let me know. I purchased the program on Friday and have been reading the manual, sample code and posts. I'm not going to win the "caught on fast" award. :-) The "4 out of last 5 bars making lower low and lower high"; I would guess this wouldn't require a loop but that is just a guess.
