I just realized that many new traders still confuse Long and Short positions. Today I will explain in detail these two concepts because they are truly the foundation of all derivatives trading.

A Long position is when you predict the price will go up. You buy at a low price and sell at a higher price to make a profit. Conversely, a Short position is when you predict the price will go down. You borrow the asset from the exchange to sell at the current high price, then buy it back at a lower price, return it to the exchange, and keep the difference.

But here’s the important part that many people overlook: the real power of Long/Short lies in leverage. You don’t need to have 100% of the funds to trade. By depositing a small margin, you can control a trading volume many times larger. For example, with $1,000 and 1:10 leverage, you can open a position worth $10,000. If the price moves in your favor by 10%, you make a $1,000 profit — doubling your account. But if the price moves against you, you could lose your entire initial capital.

This is why Long/Short is very dangerous if you don’t understand the risks. There are two main risks traders need to know:

First is Margin Call. When you hold a Long/Short position and the market moves against you, your losses will increase rapidly. If the loss exceeds your maintenance margin, the exchange will issue a warning and require you to deposit more funds. If you don’t, the system will automatically close your position (Liquidation), and your account will be wiped to zero.

Second is Short Squeeze, a trap many fall into. If a Long position has a maximum loss of 100% (if the price drops to zero), Short positions have unlimited risk because prices can rise infinitely. When an asset suddenly surges in price, Short sellers are forced to buy back to cut losses. This buying pressure pushes the price even higher. The GameStop event in 2021 is a prime example — it wiped out billions of dollars from hedge funds.

Besides speculation, Long/Short is also used for hedging risk. Suppose you hold 1,000 shares of Apple long-term but fear a short-term market decline due to bad news. Instead of selling off, you can open a Short position on the S&P 500 index or Apple itself. The profit from the Short position will offset the decline in your underlying portfolio, helping your assets stay safe through tough times.

Quick comparison between Long and Short: Long helps you profit when prices rise, and you own the actual product and can receive dividends if it’s stocks. But you lose when prices fall. Short, on the other hand — you profit when prices drop, especially useful in a prolonged downtrend, but the risk of loss is unlimited if prices spike suddenly.

An important point: do not open Long and Short positions on the same asset at the same time. Many think this will hedge their risk, but in reality, you only pay trading fees without gaining anything. However, you can definitely use Long/Short on different products simultaneously. For example, if the USD strengthens, you might Short EUR/USD but Long USD/JPY to take advantage of the opportunity.

In the crypto market, Long/Short is basically similar to stocks, but with much higher risks. Crypto operates 24/7, with extreme price volatility, and leverage can reach up to 1:100. This means liquidations happen quickly and violently compared to traditional stocks.

A common question is: when I Short an asset I don’t own, where do I get it from? The answer is you are borrowing it from the exchange via CFD or margin trading. The system automatically records this, and you only need to deposit enough margin to secure the loan.

Finally, remember that holding a Long/Short position overnight incurs overnight fees (Swap/Funding Rate). If you trade long-term, these fees will gradually eat into your profits. Therefore, risk management and understanding costs are key to success in Long/Short trading.
