One problem that is evident with your 'stlong' variable is that the
BarsSince() function is often returning a "zero" value. This is not
acceptable for the HHV(H,periods) function, as I think I pointed out in my
earlier post. So the problem at this point is not so much that the code
won't work as that it won't work with the parameters you are supplying it.
Try adding some number to BarsSince(rmbtl=0) so that you have an expression
like (BarsSince(rmbtl=0)+5) instead. This should at least get an output
instead of N/A - It does for me. Because I don't yet understand the thinking
behind the formula I can't offer further suggestions, but using a variable
as a constant does not appear to be the only issue.
You can dispense with the If function in "stlong" (to simplify the code a
little) because any output signal will be the same whether or not you use
If(). But the main task is to rethink the BarsSince() function usage so the
result is never zero and always a whole number, as required by HHV()
