Help on backtesting of new system

[jonti]

Hi
I'm not a great backtester. Could anyone help me create a backtest of this strategy?!


var lastrawtime = 0;
var BarCount = 0;
var vLastAlert = -1;
var vFlag0 = 1;
var vFlag1 = 0;

function preMain() {

setPriceStudy(true);
setStudyTitle("Long/Short");
setShowCursorLabel(false);

}

function main() {

if(lastrawtime != getValue("rawtime", 0)){
BarCount += 1;
lastrawtime = getValue("rawtime", 0);
}

if(getBarState()==BARSTATE_NEWBAR){
vFlag1 = vFlag0;
}

if(vFlag0==-1&&open()<low(-2)&&close()>=low(-2)||vFlag0==-1&&low()>=low(-2)&&close()>high(-1)){
if(vLastAlert!=1)drawShapeRelative(0, low(0), Shape.UPTRIANGLE, "", Color.blue,null,"Up"+ BarCount);
}else{
removeShape("Up"+BarCount);
}
if(vFlag0==1&&open()>high(-2)&&close()<=high(-2)||vFlag0==1&&high()<=high(-2)&&close()<low(-1)){
if(vLastAlert!=2)drawShapeRelative(0, high(0), Shape.DOWNTRIANGLE, "", Color.red,null,"Dn"+ BarCount);
}else{
removeShape("Dn"+BarCount);
}

if(getBarState()==BARSTATE_NEWBAR){
if(vFlag1==-1&&open(-1)<low(-3)&&close(-1)>=low(-3)||vFlag1==-1&&low(-1)>=low(-3)&&close(-1)>high(-2)){
drawShapeRelative(-1, low(-1), Shape.UPTRIANGLE, "", Color.blue,null,"Up"+ BarCount);
Alert.playSound("long.wav");
//Alert.addToList(getSymbol()+" "+getInterval(),"LongStop",Color.black,Color.green );
vFlag0 = 1;
vLastAlert = 1;
}
if(vFlag1==1&&open(-1)>high(-3)&&close(-1)<=high(-3)||vFlag1==1&&high(-1)<=high(-3)&&close(-1)<low(-2)){
drawShapeRelative(-1, high(-1), Shape.DOWNTRIANGLE, "", Color.red,null,"Dn"+ BarCount);
Alert.playSound("short.wav");
//Alert.addToList(getSymbol()+" "+getInterval(),"ShortStop",Color.black,Color.red) ;
vFlag0 = -1;
vLastAlert = 2;
}
}

return null;

If I am not mistaken I wrote the efs you posted (the original script is available here)
The attached revision adds Buy/Sell commands for use in back testing based on the signals generated by the script. Also, when long it paints the bars in lime and when short in red

PS. When posting an efs created by someone else please preserve also all annotations included in the original script.
