optimization results

I am sure this is in the manual simewhere but I can't seem to find it. After you run optimization, you see results that look like this:


EUR/CHF:: 48.5 6.92 6.91 => 0.814

I am guessing that the first three numbers represent the best results for the variables you chose to optimize, but what does the last part represent? (=> 0.814)

It's only the profit factor of the training run - it has otherwise not much meaning. I believe the results are explained in workshop 5.
