Yes .. looking for an indicator that plots the DIFFERENCE between the price of two pairs in a seperate window as one single line..
THIS IS NOT CORRELATION..NOR CHART TRANSPOSITION..JUST SIMPLE PRICE DIFFERENCE..
Obviously for use on pairs that have the same base currency ..eg AUDUSD v NZDUSD...

The thing is.. does any one know of one... you know of any such indicator?
As a nonprogramer it seems a very simple idea? Maybe not?
I came across CurrencyChart.mq4 by Strator ( k-v-p@yandex.ru) which plots price action of a single pair in a seperate window, I'm using this by overlaying two instances in one window with scales synchronised.. but but I dont know how to add a second pair to the code (looks very complicated) or how to plot the difference between them.
