No need technical knowledge... Just follow the signal.....

ok. but as new to amibroker, they didn't know how to solve error, cause lack of afl knowledge. so i said remove errors and repost to him. if you are expert in afl give solution to newbees. thank you.

come on! hand on yourself please
If you show me you know the syntax error no, you should be able to do it.
The solution is when the syntax error appear, click on the syntax error , the cursor will locate you the text postion.
Usually thee problem show eg "colorG een" , then delete the space.

The Corrected Code is given hereunder. Only problem was there were spaces in certain words and that was showing as an error. :thumb:

Hello

Nice code, with automation too many trend line, i prefer to draw the lines, can use the code to cleanly identify the fractal

Thanks

Code:

_SECTION_BEGIN("Fractals");
// Fractals Version 6a: 

SetBarsRequired(sbrAll,sbrAll);
xx = Cum(1);
nbar = Param("nbar",5,2,50,1); 
// define fractals
PHigh 	=	H > Ref(HHV(H,nbar),-1) AND Ref(HHV(H,nbar),nbar) <= H;
PLow 	=	L < Ref(LLV(L,nbar),-1) AND Ref(LLV(L,nbar),nbar) >= L;
HiP 	=	ValueWhen(PHigh,H) + 3;
LoP 	=	ValueWhen(PLow, L) - 3; 

PlotShapes(shapeSmallCircle*PHigh,colorRed, 0,HiP,0);
PlotShapes(shapeSmallCircle*PLow,colorGreen,0,LoP,0);
_SECTION_END();

thank you

do u need that afl i have it. its good to see afl on chart.. but performance is poor...

After 14th May 2013, suddenly why digging this thread? AFL would have come by this time, but till now if no one has published it, then it will be never.

Stop requesting again and again.

If one will not follow discipline, then the best afl in the world will not give one money. To become a successful trader, one needs the knowledge and with that discipline and patience. Everything else are BAKWAS.

So friends, please don't loss your valuable time by continuing to haunt different AFLs.

Happy trading.
