Been a while... Presenting... Relative cross currency correlation with MO's Vector Channels...
Its a mess but it is VERY interesting in spotting relative over bought, over sold... Don't worry it also hurts my eyes...
Wtf I remember trading like this in the past off of netdania charts,but only with 2 polar opposite pairs like ie eurusd & usdchf. The idea was to use the computer screen as support and resistance (before learning about the ratzone) Wait for price on each currency to reach the edge of the screen and form an open gap. Enter at S/R levels in attempts to close the gap. Yes, Visually it looks best with line charts zoomed out as you have here.
