Mybe that you are saying right but according to me you opened as yours as positions as when ever the market is in your favor, the pair that you have trade in the market , is slow in variation then try to see the situation if further down then to stop and close your positions ! yes u can open potion for long time if you have swap free account this is best cool oppertunity for forex traders they can easily earn money after closing position 1 or two month later but keep in mind always take care of your balance before taking such type of big risks
