Giełda chińska
Akcje chińskie, którymi handluje się najczęściej
Te akcje są obecnie bardziej popularne niż Britney i mają największy wolumen obrotu na rynku. Ogromne wolumeny chodzą zwykle w parze z wysoką wyceną i często są wynikiem dużej liczby zleceń realizowanych na określonych poziomach cenowych, gdy na rynek wchodzą wieloryby. Jak każdy trader wie: tam, gdzie jest aktywność, jest potencjał na dużą zmienność, a tam gdzie jest zmienność, jest też potencjał na zyski. Giełda chińska ma wiele możliwości, sprawdź sam.
