Hi Ricky,
Finally what I did was to generate strategies from October 2018 through October 2023, 5 years for EURUSD. I set the OOS to 30% to see profit for last one year of trading. By using 5 years of data the indicators used have settings that generate profits over the long term which then includes many periods of trending and ranging periods. This is why Petko uses 5 years of historical data when generating strategies. I then looked at profits generated while trading during the month of November 2023. Results show a profit of $188.75 for the month of November 2023 with 13 trades.
What all this testing shows is when generating strategies you need to include multiple periods of trending and ranging markets to create strategies that will work well in future market conditions.
Also by using an OOS equal to one year shows how well the indicators work when actually trading over a future one year market conditions.
