You can prevent more loss by selling your position exactly the same as by "hedging" with an opposite position. There is absolutely no benefit, none at all, to this "hedging" over just simply selling the open position.Yes open two order also will charged by spread fee and this commission will giving more benefit for broker I think, as I know hedging position is only to prevent from more loss because order against the trend, and with open oposite order, where ever price move floating loss remain same.
