Hi, please help me,

this script is writing out the data from opened chart. (high, low....)

I would like to modify this script, to take as input the currency pairs

(aud-usd, or eur-usd...) and the time frame and write out the data to file

extern datetime BeginDate = D'2009.02.11';
extern datetime EndDate = D'2009.03.31';
extern string Separator = ",";

void start()
{
int i, b=0, bb=0, eb;
string comm, st;
string fn=Symbol()+Period()+" "+
TimeToStr(BeginDate, TIME_DATE)+"-"+
TimeToStr(EndDate, TIME_DATE)+".csv";

for (i=Bars; i>0; i--)
{
if (Time[i]>=BeginDate && Time[i]<=EndDate)
{
if (bb==0) bb=i;
st=TimeToStr(Time[i], TIME_DATE)+Separator+

DoubleToStr(Volume[i], 0);
WritingLineInFile(fn, st);
b++;
eb=i;
}
}

comm="Íŕ÷ŕëî: "+TimeToStr(Time[bb], TIME_DATE|TIME_MINUTES)+"\n";
comm=comm+"Ęîíĺö: "+TimeToStr(Time[eb], TIME_DATE|TIME_MINUTES)+"\n";
comm=comm+"Âűăđóćĺíî áŕđîâ: "+DoubleToStr(b, 0);

Comment(comm);
