You have explained in your basic and general words about cross asset correlation. Correlation between different currencies can be measured by using a scale I agree with it as you have also explain a little about reading of its scale that it is calculated as a scale as -1, 0, + 1 as well as you have also explained some of the portfolio management strategies. The more good things which is looking much presentable is that you have also shared some of the most interesting charts of the historical data which are showing that you made reasonable efforts to participate in this challenge I wish you success...
