Hi,

Which is the range of the values shown by the Linear Regresion Angle indicator ?
I usually see values between ~ -0.1 and + 0.1.
What they mean ? degrees/radians ?

I got a look at the ta_lib code for the Linear Regression Angle
and I see:

outReal[outIdx++] = Math.atan (m) * ( 180.0 / 3.14159265358979323846 );
where outReal is the returned value for the indicator

Math.atan() returns a value between -pi/2 .. pi/2
and the above would translate in a range -90 .. 90 which would be degrees
so that the indicator in JForex should display also ranges between -90 and 90
but I only see values small values as above.

Can you clearify me ?
I need to be sure the linear regression angle fits into a range but for that
I have to know what it displays degrees/radians/pips or what ?
Thank you

Hi,
Linear Regression Angle is a Ta-Lib indicator, the following is an extract from the Ta-Lib documentation:
Linear Regression is a concept also known as the "least squares method" or "best fit." Linear Regression attempts to fit a straight line between several data points in such a way that distance between each data point and the line is minimized.

For each point, a straight line over the specified previous bar period is determined in terms of y = b + m*x:
TA_LINEARREG: Returns b+m*(period-1)
TA_LINEARREG_SLOPE: Returns 'm'
TA_LINEARREG_ANGLE: Returns 'm' in degree.
TA_LINEARREG_INTERCEPT: Returns 'b'
TA_TSF: Returns b+m*(period)
