if i optimize an ea for a long period of more than 15 years, do i still run the risk of overfitting?

[Pipperoni]

Test and curve fit it on 15 years of data, and than (forward) test it on 15 years of OTHER data of the same instrument. Than ... you will be 1 disappointment richer.

@luanainteglia this mainly depends on the style of your ea and which trade logic it applies.
