A clip from Corey Saxe ....to convert radians to degrees and vice versa. AB native functions expect/yield radians
Y= Price;
pi = 4 * atan(1) ; //Pi
RTD = 180/pi;//radians to degrees
DTR = pi/180;//degrees to radians
Here's a clip from the users guide with the conversion in the title statement.
Hope this helps
JOE
x = Cum(1);
lastx = LastValue( x ); Daysback = 20; aa = LastValue( LinRegIntercept( Close, Daysback) );
bb = LastValue( LinRegSlope( Close, Daysback ) );
y = Aa + bb * ( x - (Lastx - DaysBack) ); Plot( Close, "Close", colorBlack, styleCandle );
pi = 4 * atan(1) ; //Pi
Plot( IIf( x >= (lastx - Daysback), y, -1e10 ), "LinReg", colorRed );
Title="ANGLE="+WriteVal(bb)+" RADS"+", ["+WriteVal(45*bb/atan(1),1.0)+" DEGS]"
+ "\n" + WriteVal(bb*(180/pi));

The angle to the vertical (if memory is OK - double check me) in radians of a line with slope x = atan(x). And the angle in degrees is 45 * atan(x) / atan(1).
