Hello,
In addition to that, if you want to accumulate 5 over
subsequent days (so it adds 5 to every bar after initial one) you can
use:
Surrogate = Close[ 0 ] + Cum( 5 );
Best regards,

Not sure what you are really after.
What you did was
create a reference to YESTERDAY's close. It will change
every day as you
discovered. If you just want the first close of the
data to remain
constant, try this:
InitalSurrogateClose = C[0] + 5;
Gets and
stores the very first piece of data into a NUMERIC variable.
This is
essentially now a CONSTANT you can use in further
calcs.

Subject: [amibroker] Creating a surrogate for
price?
Question: How do I reference the first close in a data set,
perform a
calculation on it and that becomes the new surrogate close going
forward?
ie. Dow close 5 yrs ago = 9500
surrogate dow close = 9500+5
If I use:
InitalSurrogateClose =
ref(c,-1)+ 5 ;
SurrogateClose = InitalSurrogateClose + 5;
it works
for the first bar in the data set but then continues to
reference the real
close. I need to Isolate this first surrogate close
and I an just not
seeing it. Please help if you understand what I'm
after.
Thank
you!
