Hedging in forex is a strategy used to reduce or offset the risk of unfavorable price movements in a currency pair. It involves opening a trade that goes in the opposite direction of an existing or anticipated trade to protect against potential losses.
Profession trader's definition: The market is against you. And you want to HODL and refuse to cut loss. So you trade another product. And take a small position to trade with the new market direction. Professional writer's definition: Hedging is a risk management strategy employed to offset losses in investments by taking an opposite position in a related asset. The reduction in risk provided by hedging also typically results in a reduction in potential profits. Hedging requires one to pay money for the protection it provides, known as the premium. Hedging strategies typically involve derivatives, such as options and futures contracts.
So far I know hedging means maintaining both buy and sell positions and taking off either side for maximum profit.
One of the most common hedging methods is to open positions opposite to existing ones. For example, if you have a long position (buy) on a certain currency pair, you can open a short position (sell) on the same currency pair. But you need to be able to exit with a profit on such opposite positions, which is not so easy for many traders.
