Each color is a different currency. In
>>20687632, it's simply the $DXY equivalent for that currency, scaled between -1 to +1.
In this image, I'm instead transforming the index into a rate of change by looking at the slope between two values and averaging it. Then, a positive slope is bright, while a negative slope is red.
It's still scaled (from 0 to 1), and the most recent color change is telling me that either CAD is softening, or JPY is rallying, or both. Curious to see if I blow my ass out on this one, since it's about $20 of risk against the $35 left in my forex account. I don't want to top it up but I'm really hoping it works in my favor this time
