Quote from jcl:
No reason not to believe it, as ~80% profit in 7 months can be a quite realistic result.
However, the equity curve looks as if it's calculated with reinvesting, which makes it hard to tell if the system is any good. And you can't see data mining in an equity curve anyway. So, posts with some equity curve and "any good" questions are pointless. Better describe your backtest and optimization methods and ask if they are any good.
