Help with indicator

Can anyone review the code and explain the vertical lines that are drawn on the chart?

Here is the code:

#property strict
#property indicator_buffers 4
#property indicator_chart_window

input int InpATRperiod=14; // ATR Periods
input float InpRisk=1; // Risk Size %
input float InpSLfactor=1.5; // Stop Loss as a factor of ATR

input int InpFontSize=12; // Font size
input color InpColor=Red; // Color
input int InpBaseCorner=CORNER_RIGHT_UPPER; // Base Corner 0=UL,1=UR,2=LL,3=LR
input float InpFixedATR=0; // Fixed ATR points

string AccntC=AccountCurrency(); //Currency of Acount eg USD,GBP,EUR
string CounterC=StringSubstr(Symbol(),3,3); //The Count Currency eg GBPUSD is USD
string ExC=AccntC+CounterC; //Create the Pair for account eg USDGBP

double UpTicks[];
double DownTicks[];

double Diff[];

SetIndexLabel(0,"UpTicks");

return(0);
}

Looks like a nice quote. If you are not sure about it, I suggest trying it on your demo account first.
