1. Two-way trading means that in futures trading, traders can buy futures contracts as the beginning of futures trading (called buying positions) or sell futures contracts as the beginning of trading (called selling positions), commonly known as "short selling".

2. Two-way trading is one-way trading, which can be bought first and then sold (long position) or sold first and then bought (short position), so that in the process of price decline, investors can increase their profit opportunities by shorting. In other words, no matter whether the price goes up or down, there is a chance to make money. Two-way trading is also one of the differences between futures and stocks.
