Not really though, you just trade points instead of dollar value, whereq point equals some value for ES its 12,5$ per tick. Plus futures like it name impies trade for future value so its value little bit higher than actual item, depending how much time till contract expiry. Closer expiry time more on pair value would be. That point value calcualted based on money cost (FED rate)
