What is buy long and sell short in Binance futures?

In Margin trading, “Long” refers to buying at a low price and then selling at a higher price . In this way, you can earn a profit from the price difference.

By going long, a trader buys a futures contract with the expectation that it will rise in value in the future. Conversely, a trader sells a futures contract to go short, to bet on prices to decline in the future.

Buy at a lower price. Sell at a higher price.
