[amibroker] Re: How to plot lines 10% up and down from zero line of a monthly indicator

["Mike" <sfclimbers@xxxxxxxxx>]

I'm not clear on what it is you are asking for. Are you wanting +/- bands surrounding your ROC similar to bollinger bands? Or are you asking for the +/- bands but centered on the zero line? Or are you wanting a constant line parallel to zero for each of +10 and -10?

Here is an example of all three. Hopefully one will be what you are after. I think the second one is what you want.

TimeFrameSet(inMonthly);
MonthlyROC = ROC(Close,10);
TimeFrameRestore();

Expanded = TimeFrameExpand(MonthlyROC, inMonthly);
Delta = abs(Expanded) * 0.10;
Plot(Expanded , "Monthly ROC", colorBlue, styleLine);
Plot(Expanded + Delta, "Plus 10", colorGreen, styleLine);
Plot(Expanded - Delta, "Minus 10", colorDarkRed, styleLine);

Plot(Delta, "Plus 10", colorGreen, styleThick);
Plot(-Delta, "Minus 10", colorDarkRed, styleThick);

Plot(0,"ZERO LINE",colorBlack, styleThick);
Plot(10, "Plus 10", colorGreen, styleThick);
Plot(-10, "Minus 10", colorDarkRed, styleThick);
