size=2>Gilles,
put
another way flip simply hold the condition true until cond 2 "Flips" it to
false. Consider this
<FONT face=Arial color=#0000ff
size=2>
<FONT face=Arial color=#0000ff
size=2>Cond1=c>10;
cond2
c<8;
<FONT face=Arial color=#0000ff
size=2>
using
flip if the price of your stock rises to 11 then drops back to 9 the condition
is still considered true (1), even though your price is now below the thresh
hold. Once the price drops below 8 the cognition is now considered (flipped to)
false (0).
Regards,
Jayson

Graham again( was AFL help...)Gilles, sorry my French
is a bit rusty, over 30 years since learning someand none understood me
anyway on my last trip to ParisIf you do an exploration (with cond1 and
cond2 in the columns) over a periodwhere the conditions exist you would see
that once Cond1 becomes 1 normallythe next day it returns to zero, but the
flip will carry forward that 1until Cond2 is true. At this day Cond1 becomes
0 and Cond2=1.Hope this helpsCheers,Graham<A

[amibroker] Graham again( was AFL help...)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
