Hedging is to conduct two transactions at the same time that are related to the market, in opposite directions, of equal quantity, and with profits and losses offsetting. Hedging can lock in losses when a trade loses and hold on to profits when it makes a profit. It is also very simple to do hedging transactions. For example, on the Domain Kingdom platform, we can go long on the U.S. dollar against the Japanese yen on one side and short on the stock index on the other side. This is a kind of hedging.
