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.
