It is the process of testing a specific trading strategy or idea, and see how it behaved in the past, or, simulate it with past data. All this with the aim of measuring the effectiveness of that strategy/idea.

Ariel,

Why on earth do you compare the performance of a currency pair to the S&P 500 ? These are totally different asset classes. FX can be used as a diversification away from bonds and stocks and the performance (which is related to the leverage deployed) is not comparable.

it'a an example... But you're right, I would compare s&p with equities... But again, this was intended to show how to backtest, and you can benchmark your results with anything you think is best. The idea is to see how good/bad is your strategy doing.

Yeah, it's probably an apples & oranges comparison to some extent. Regardless, it still goes to the classic argument of whether to choose a strategy (active management) or to just invest in a broad market index. Showing a favorable comparison to an SPY buy-hold strategy is arguable an almost universal step 1.
