hi,
After looking at how SAR is plotted:
Plot( SAR( acc, accm ), _DEFAULT_NAME(), ParamColor( "Color",
colorCycle ), ParamStyle("Style", styleDots | styleNoLine, maskDefault
| styleDots | styleNoLine ) );
I find the algorism is not implemented using the Plot function, it is
in the SAR function. So my suggestion is:
A function, let's call it MyStop:
//pls refer to AFL syntax, I am a newbe
function (return type) MyStop(...){
...
if(LongSignal){
stpValue=[calculate long stop value];
}
else{
stpValue=[calculate short stop value];
}
return stpValue;
}
Then plotting is simple and easy:
Plot( MyStop(...), ...);
//Note here: Just as SAR, plot it as dots, not line. If line, looks
too strange.
