Best backtesting years period

 

Hi,

Iam working on an EA wich works with price action setup (pinbar only) and EMAs and I have doubts on which period should I make the backtesting. There are many articles of optimization and backtesting of stategy but there is no reference to the period to use.

Should we use an random period? Or a period that as some financial problem? Is there any favourite period (years) to use on forex? I was thinking to use:

=> 2006 - 2010 for Training Series and parameters optimization;

=> 2011 - 2015 to testing Series;

 

Because the chosen training period will influence the EA parameters and it will behave different in some occasions. What are your advices?

Best regards,
