OK, the portfolio we have at the moment - how to select the shares of the instruments in the portfolio?

Here is Leonid's simple example of a portfolio of two instruments. Here, theoretically, you can pick it up by eye. But what if there are more instruments?

Perhaps this indicator (or rather a set of indices) would be a good idea = https://www.mql5.com/ru/code/10096

But all questions about it - only to the author! I am not an expert on it.

 
Thank you. I'll have to think about it.
 
pair trading and spread trading are based on the immutability of correlation coefficients. In forex, in the medium and long term, they change dramatically, right down to the sign. In fund and commodity markets they are more stable. I think so....

For pair trading, correlation is irrelevant.

Have you ever seen an example of pair trading for two instruments that have the property of cointegration and, at the same time, have a low correlation?

And I doubt that cointegration in pure form exists in forex - it would mean a risk-free TS based on paired trading (for classically cointegrated series the spread is guaranteed to 0)
