The Test period is 1990 to May 2017 (you can kind of see that from the years at the top of the chart).
MDD did go up 3.5%, but overall profit did not go down.
It went from 31,000% to 169,000%.
Over 5 times increase in profit for just a 3.5% increase in MDD.
Profit factor did go down, but Calmar Ratio went up.
And for that 5 times increase in profit it only added another 2000 trades over 27 years.
