<SPAN

The
Flip() function keeps a signal active for every bar between the specified start
and end of the signal.
The
Exrem() function does the opposite. It makes a signal active only on the first
occurance.
<SPAN
class=181005522-24032003>
Oops,
replace && with AND. Sorry, I sometimes confuse the operators in
different programming languages.
<SPAN
class=181005522-24032003>
<SPAN
class=181005522-24032003>Perhaps this will work for you now:
<SPAN
class=181005522-24032003>
startOfCond1 =
...endOfCond1 = ...
startOfCond2 =
...endOfCond2 = ... cond1 = flip(startOfCond1,
endOfCond1);cond2 = exrem(startOfCond2, endOfCond2); detection
= cond1 AND cond2;
<SPAN
class=181005522-24032003>Cheers,

[amibroker] Sequence of two conditions
Folks,
maybe you have a solution for the
following:
IŽd like to detect the first occurence of
cond2 after cond1 has happened.
I seemingly canŽt use Valuewhen function
since it calculates from the last bar, not from cond1 (i.e. I nedd a
calculation forward rather than backward).
So, in case that there are several instances
of cond2 after cond1, I might get a wrong result.
Could anyone help me, please?
Thanks a lot
