Can anybody modify this afl.

As seen in the image it is full of fib.levels in the screen. how to remove these keeping only the last one.

here is the code:

_SECTION_BEGIN("Price");
SetChartOptions(0,chartShowArrows|chartShowDates);
SetBarFillColor(IIf(C>O,ParamColor("Candle Up Color",colorBrightGreen),IIf(C<=O,ParamColor("Candle Down Color",colorRed),colorLightGrey)));//Up=Lime/Down=Red
Plot(C,"Price",IIf(C>O,ParamColor("Shadow Up Color",colorBlack),IIf(C<=O,ParamColor("Shadow Down Color",colorBlack),colorLightGrey)),64,0,0,0,0);//Up=DarkGreen/Down=DarkRed/64=Candle/128=Bar
SetChartBkColor(ParamColor("Panel Color",colorPaleGreen));
SetChartBkGradientFill(ParamColor("Upper Chart",colorLightGrey),ParamColor("Lower Chart",colorLightGrey));
dec=(Param("Decimals",2,0,7,1)/10)+1;
GraphXSpace=Param("GraphXSpace",20,-10,25,1);
_SECTION_END();

_SECTION_BEGIN("Fibonacci Fractals");

PLowPrice = ValueWhen(PLow,L);

Bear = ValueWhen(PHigh, DateTime());
Bull = ValueWhen(PLow, DateTime());

PlotShapes(shapeSmallCircle*PLow,colorGreen,0,L,-10);
PlotShapes(shapeSmallCircle*PHigh,colorRed,0,H,10);

//Plot(PLowPrice, "Fractal Low", colorGreen, styleDots | styleNoLine);
//Plot(PHighPrice, "Fractal High", colorRed, styleDots | styleNoLine);

phase = IIf(bull > bear, 0, 1);

//Fib Level Calculation
//If previous fractal was down fractal, then Fib Level is worked out
//by subtracting the down fractal from the up fractal and vice versa

Title =

// -- will comment out the code.
For example in the above plot - is used to plot the levels.
Plot(Level0382,"38.2%=",colorGold, styleDots | styleNoLine|styleNoRescale );

// Plot(Level0382,"38.2%=",colorGold, styleDots | styleNoLine|styleNoRescale); - means the code will be commented out.

So just use // and comment out which ever plot levels you want to comment out.
And if you remove the // to uncomment.

Thank you JK. But my problem is different.i dont want the previous fib.levels which are normally of no use. I want only the latest plotted one on the screen.
