For most things, AB is way simpler that other languages out
there.
Try (one line):
plot(C-ref(C,-1), " Change from Yesterdays Close
",colorred,1);
-CS

Subject: [amibroker] simple code
question
I have had Amibroker for awhile now but continued to use
TradeStation
because that is what I have been used to and it worked for
most of
what I needed. I decided to dust off Amibroker and see what
it can
do but I am having a coding problem. I want to plot a simple
indicator that measures change.
In TS, the formula is a
relatively simple:
Chg = Close - Close[1];
Plot1(Chg);
In
Amibroker what I have is:
for( i = 1; i < BarCount; i++
)
{
Chg = Close[ BarCount - 1 ] - Close[ BarCount - 2
];
}
Plot (Chg, "Change", colorBlue, styleLine);
The problem is
that the indicator's value is correct on the last bar
of the chart, but it
plots that same value on every bar preceding it,
so all that results is a
straight line. I tried it with the Plot
statement inside the For
loop but then all I get is a straight line
with many instances of the same
value (obviously due to the loop).
I figured I could work it out from
the code for Rate of Change, but
that is simply coded with the 'ROC'
function, and the code for the
functions are not available to my
knowledge.
Any help is appreciated, thanks.
