Here's code for Gann Angles originally coded by Mobius and modified for highs and lows by someone else. I posted this for those who already know how to use Gann's Angles. There are courses in Udemy.com, if you don't know already. Also look here: The Best Gann Fan Trading Strategy


Code:
# Gann Angles by Mobius
# Modified
# V02.03.03.2019
#hint: The primary Gann angles: 1X2, 1X1 and 2X1.  1X1 is moving one unit of price with one unit of time. Additional angles 1X8, 1X4, 4X1 and 8X1.

def barNum       = if IsNaN( close ) then Double.NaN else BarNumber();
def endBar      = HighestAll( barNum );
def startBar    = if endBar <= numBars then 1 else endBar - numBars;

def hData       = If( barNum < startBar, Double.NaN, high );

def Apex = HighestAll(hData);
def Apex_Bar = if high == Apex
                then bar
                else Double.NaN;

def Nadir = LowestAll(lData);
def Nadir_Bar = if low == Nadir
               then bar
               else Double.NaN;

                      then Nadir
                      else FirstValue[1];

Any way to modify this to draw a -45 degree angle from the HOD and a 45 degree angle from the LOD?
