### Comment:
Pretty solid idea. I think it would be useful to track the RMSE across different tests, though I might add the scaling I use would make it slightly confusing. 
  
 I also track the correlation between the forecast and the true close, though this is a more subjective measure. 
  
 Thanks for the input man.

Np. Good luck with the project. Be sure to interpret small RMSE correctly because of the scale. You can also compute MAE and do interse transform to see what kind of $ value it has...
