One of the most common way to research CFD and Forex positions is through analysis, that relies on interpreting data from past market performance to establish some kind of prediction towards future pricing. However, it should be noted that past performance of CFDs is not an indication nor guarantee of future performance. It means that traders might use the data from past performance to speculate on the market, but they should not rely on it. When referring to past performance, an investment firm must disclose the sources, currency, commission paid and a warning that the figures are merely historic.
