how to create a 2 % system

[shogun]

i am trying to create a efs which will draw a line 2% above the current swing low and 2% below the current swing high. the 2% would be of the current share price ,
so if the share price was 400 the line would be drawn 8 above the current swing low,
is this possible any help will be much appreciated

thanks.

See if this is what you want.

You can change the percentage and turn the lines on and off.



function preMain() {
setStudyTitle("% Pivot");
setDefaultBarFgColor(Color.green, 0);
setDefaultBarFgColor(Color.red, 1)
setDefaultBarThickness(2, 0);
setDefaultBarThickness(2, 1);
setCursorLabelName("High Pivot", 0);
setCursorLabelName("Low Pivot", 1);
setPriceStudy(true);

var fp1 = new FunctionParameter("vPercent", FunctionParameter.NUMBER);
fp1.setName("% of Pivot");
fp1.setDefault(2);
fp1.setLowerLimit(0);

var fp2 = new FunctionParameter("vDrawPivot", FunctionParameter.STRING);
fp2.setName("Draw Lines");
fp2.addOption( "Yes" );
fp2.addOption( "No" );
fp2.setDefault("No");
}

var vHighLine = null, vLowLine = null;

function main(vPercent, vDrawPivot) {


if (getBarState() == BARSTATE_ALLBARS) {
}

if ( vDrawPivot == "Yes"){

vPercent = vPercent/100;

if ( high(-2) < high(-1) && high(-1) > high(0)){
vHighLine = high(-1)*(1-vPercent);
drawLineAbsolute(-2, vHighLine, 2, vHighLine, PS_SOLID, 3, Color.green, "nHL");
}

if ( low(-2) > low(-1) && low(-1) < low(0)){
vLowLine = low(-1)*(1+vPercent);
drawLineAbsolute(-2, vLowLine, 2, vLowLine, PS_SOLID, 3, Color.red, "nLL");
}
return;
}
return;
}

whatever thanks this will be a big help, its not exactly what i am after but it gives me some building blocks to start with as i did not have a clue where to start, alexis put me onto a efs by jason on zig zags which might be able to pinpoint the swing lows/highs,

are there supposed to be 2 " returns; " at the bottom of the script or is one a printing error.
