Don't have the time right now to write it, but a quick scan suggests that it
could be easily written as a function using nested "iff" statements e.g.
iff(cond,iff(cond,true, false) , iff(cond,true, false) ) statements - same
conditional syntax as Excel. Define the function as a series function and you
can check the previous period value of the function - often eliminates the need
for variables. Too complex for one function, break it into several. A complex
system can be written in QE (I've done some complex QE functions nested 6-8
levels deep) but it's a _lot_ easier to do in PE and the really complex systems
can only be done in PE.
