Fixed a stupid copy/paste mistake. Now you can see the 0.618 line too.
Added transparency: 45
P line thickness is 2, the rest are 1
Please adjust it to your liking and screen res.
Any ideas or requests? Please post as comments.
PS! The way I use it is that I fire it up, use line tool to draw over today's and yesterdays lines and then hide the script. This way charts zoom in/out, scale etc work better.
