Hi there, i would like to have a analysis done on a graph/data etc. Im attaching a graph that contains the USD/ZAR and the platinum price $/ounce. Definitions: Blue line is USD/ZAR(USD is US $, ZAR is South African Rand). Its a daily graph, this can back 10years. I trade futures and ive noticed there is a reverse or inverse correlation between the two entities. What i would like to know/have is some kind of a model/indication of what that relationship exactly is. For example, what is the typical time lag between the USD/ZAR moving vs the platinum price moving, if the USD/ZAR moves by x% or cents how much will the plaitnum price move. This i can use to try and determine trading positions. At this stage i do not have the data behind the graphs. I am still look to where i can find it.
