StdError, calculate Linear Regression, divisor starts at 0, slope becomes NaN. bug

[balltrader]

I think I discovered a bug in the calculation of linear regression in the built-in indicator StdError

On the reading of the first bar of the data series, the variable named "divisor" will be set to 0, and the calculation of the variable named "slope" will result in a NaN value. The values of intercept and linReg rely on slope, therefore their values are also NaN.

This only seems to occur on the first bar, but I was using the calculated value of linReg to set the value of my custom series, and then passing that custom series to the SMA method, and that is how I discovered the Nan bug.

Consider testing the value of divisor inside the IsFirstTickOfBar conditional.

psuedocode

if (divisor != 0 )
{	Print("divisor is not 0"); 	}
else
{      Print("divisor IS 0, so we set it to 1 ");
	divisor = 1;
}
