I used R and the rank function to create the following ranks for the original var x : x average first last random max min 3 4.5 4 5 5 5 4 1 1.5 1 2 2 2 1 4 6.0 6 6 6 6 6 1 1.5 2 1 1 2 1 5 8.0 7 9 9 9 7 9 11.0 11 11 11 11 11 2 3.0 3 3 3 3 3 6 10.0 10 10 10 10 10 5 8.0 8 8 7 9 7 3 4.5 5 4 4 5 4 5 8.0 9 7 8 9 7 I am struggling to implement the min -version in MQL5. First, you probably need to sort the Array but you need to take care of the original order. How the ranks are assigned manually is quite logical but I have no clue how to implement this in MQL5.
