Hi,

I am trying to test / understand RateOfChange results so have attempted to create a test set. These are not working and I post one test set code below:

Why does the VolumeRateOfChange work but RateOfChange does not with the following error? (Message::name: "Message name \!(\"RateOfChange\"::\"bprcss\") is not of the form symbol::name or symbol::name::language.")

FinancialIndicator["VolumeRateOfChange", 2][{{{2000, 1, 1}, 100 {1, 1, 0, 0, 1}}, {{2000, 1, 2}, 
   100 {0, 2, 0, 2, 2.01}}, {{2000, 1, 3}, 
   100 {2, 3, 2, 3, 3}}, {{2000, 1, 4}, 100 {3, 3, 2, 1, 1}}}]

%[{2000, 1, 2}]

FinancialIndicator["RateOfChange", 
  2][{{{2000, 1, 1}, 100 {1, 1, 0, 0, 1}}, {{2000, 1, 2}, 
   100 {0, 2, 0, 2, 2.01}}, {{2000, 1, 3}, 
   100 {2, 3, 2, 3, 3}}, {{2000, 1, 4}, 100 {3, 3, 2, 1, 1}}}]

%[{2000, 1, 2}]

Thanks, --Christian
