Lows are correctly plotted with all red boxes. pls help.
 _SECTION_BEGIN("MA5");
 UpTrend=StaticVarGet("StaticUpTrend");
 //Plot(C,"",colorBlue,64);
 
 MA5=MA(C,5);
 Plot(MA5,"",colorAqua,styleDashed);
 //FINDING PEAK
 TOP1=(Ref(MA5,-1)>Ref(MA5,0) //RIGHT SIDE
   AND Ref(MA5,-1)>Ref(MA5,-2));//LEFT SIDE
 
 MA5_HValue =  ValueWhen(TOP1,MA5,1);
 UpTrend=IIf(Ref(MA5_HValue,0)>Ref(MA5_HValue,-1),True,
       IIf(Ref(MA5_HValue,0)==Ref(MA5_HValue,-1), Ref(UpTrend,-1),False)   );
 Vcolor1=IIf(UpTrend,colorGreen,colorRed);
PlotShapes(shapeSmallCircle,Vcolor1,0,MA5_HValue,0,0);//Red OR Green
StaticVarSet("StaticUpTrend",UpTrend);
_SECTION_END();

There is lots of help available, but you need to ask more specific questions.

What parts of the model do you need help with?
