Re: [amibroker] Creating a HHV Indicator

Sorry (getting late).  Just noticed that startplotbar is wrong:
 
startplotbar = selectedvalue(barindex()) - extendline; //hhv line starts at selected bar
 
Don't have time now to work out starting from hhv bar so take a crack at it.

Not sure I fully understand what you want but try something along these lines which assumes that you select a bar and that you only want the HHV line drawn from the HHV bar associated with the selected bar.  If that's not right then you can tweak the code to produce what you want.
 
hhvperiod = param("hhvperiod", ....
extendline = param("extendline", ...; //max = blank space specified in preferences
startplotbar = selectedvalue(hhv(h, period) - extendline;
plot(iif(barindex() >= startplotbar, selectedvalue(hhv(h, period)), null), "", color, styleline, null, null, extendline);
