John L, here is the answer to one of your questions:

As you only want the formula to return 1 (true) or a 0 (false) you don't really need IIF() function. Actually both lines could be as follows:
NewHighs = HHV(H,5) >= HHV(H,40);
NewLows = LLV(L,5) <= LLV(L,40);
This is explained in AFL Reference Manual here:
http://www.amibroker.com/guide/a_language.html
Go to paragraph "Conditional function IIF()".
