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?
