Gilles, sorry my French is a bit rusty, over 30 years since learning some
and none understood me anyway on my last trip to Paris
If you do an exploration (with cond1 and cond2 in the columns) over a period
where the conditions exist you would see that once Cond1 becomes 1 normally
the next day it returns to zero, but the flip will carry forward that 1
until Cond2 is true. At this day Cond1 becomes 0 and Cond2=1.
Hope this helps
Cheers,
Graham

Graham, You're right, that's not the problem, but...can you
express :Cond3 = Flip(Cond1,Cond2);in english?
Well, french would do even better, but :o)
Something obviously is missing in my brain, but I can't see the
relationship between this line and the crossings that are sooo easy
to see on a graph....
Thanks for your patience, I owe you a couple of bbelgian) beers! Gilles
