Quote from ammo:
it just came out in 86, a guy next to me in the pit was hand drawing it on an index card,showed me how to draw the pics,and just learned it by repetition afterwards, didnt start doing the multi day charts til o8 when picasso pointed out that it was available on tos,in 86 it worked like a charm in the 80's early 90's,the spx had a 3 pt daily range and traded in nickels,you hand charted it and got your trendlines by marking up the wall street journal , a 60 pt dow move back then was big ,so was a 5 pt spx move, back then you knew exactly what was going on a much larger percentage of the time and less people had adopted it so it was a big edge, the majority of floor traders back then didn't believe in charts, one adage was that every ship at the bottom of the sea was loaded with charts
