Hi guys,
I'm trying to get the standard deviation for each stocks. So far I have the following, but nothing comes back in the exploration.
Period = 20;
CloseTotal = Close[0];
CloseMean[0] = Close[0];
SumDeviation =
0;
SqDev = 0;
for( i = 0; i > Period; i++ )
{
CloseTotal = CloseTotal + Close[i];
CloseMean[i] = Close[(i * -1)];
}
Mean = CloseTotal / Period;
for( i = 0; i > Period; i++ )
{
CloseMean[i] = Close[i] - Mean;
}
for( i = 0; i > Period; i++ )
{
CloseMean[i] = CloseMean[i] * CloseMean[i];
}
for( i = 0; i > Period; i++ )
{
SumDeviation = SumDeviation + sqrt(CloseMean[i]);
}
SqDev = SumDeviation / (Period - 1);
SqDev = sqrt(SqDev);
Filter = SqDev;
AddColumn( SqDev, "Standard Dev");
Thanks for any help!
