As you go about evaluating the profit and loss, drawdown and smoothness of the equity curve increase, you’re likely to focus on the one set of parameters that looks best. This is the first danger. It’s better to look for a cluster of superior results than for just one outstanding set of parameters. Choosing parameters that are in the middle of a good cluster of results are likely to lead to more consistent results in the future.
