Long and Short Strategies in Margin Trading: From Theory to Practice

Margin trading offers traders two opposing strategies — long and short positions. These tools allow for profit both when the asset’s price rises and when it falls. Understanding how both positions work is critically important for successful leverage trading.

What are long and short positions

A long position is a bet on the price going up. A trader opening a long predicts that the asset’s value will increase in the future. The strategy is straightforward: buy the asset at the current (or lower, using leverage) price and sell it at a higher price, locking in the difference as profit.

A short position operates on the opposite principle — it is a bet on the price decreasing. If a trader expects the value to fall, they can borrow the asset, sell it immediately at the current price, and then buy it back at a lower price, returning the loan and keeping the profit.

Mechanics of a long position: an example with increasing value

Let’s consider a specific scenario. A trader expects the price of BTC to rise in the coming days.

Initial parameters:

• Trading pair: BTC/USDT
• Current price: 68,000 USDT
• Leverage: 5x
• Spot account balance: 13,600 USDT

With these conditions, the trader can buy 1 BTC, even though their own funds amount to only 13,600 USDT. The system automatically provides a loan of 54,400 USDT (68,000 × 4). After placing the order, the position is open: the spot account holds 1 BTC valued at 68,000 USDT.

After two days, the BTC price increases to 71,000 USDT. The trader decides to close the position by selling 1 BTC and repaying the loan of 54,400 USDT. The final calculation:

Profit = (71,000 − 68,000) × 1 = 3,000 USDT

Mechanics of a short position: an example with falling value

Now, let’s examine the opposite scenario, where the trader expects the price to decrease.

Initial parameters:

• Trading pair: BTC/USDT
• Current price: 68,000 USDT
• Leverage: 5x
• Spot account balance: 13,600 USDT

The trader opens a short position on 1 BTC. The system borrows 1 BTC and immediately sells it at the current price (68,000 USDT). Now, the spot account contains 68,000 USDT in USDT equivalent.

The forecast is correct: after two days, the BTC price drops to 63,500 USDT. The trader buys 1 BTC for 63,500 USDT and repays the loan. The final result:

Profit = 68,000 − 63,500 = 4,500 USDT

Key differences between long and short

A long position implies that profit depends directly on the price rising — the higher the asset goes, the more you earn. A short position inverts this logic: profit increases as the price falls.

Leverage amplifies both effects. With a correct market prediction, leverage can significantly increase the percentage return. However, if the prediction is wrong, it can also greatly increase losses.

Important clarifications

The examples above do not account for trading fees or interest rates for borrowed funds. In real operations, these costs will be deducted from the final profit. To fully understand the expense structure, it is recommended to review detailed information on trading commissions and interest rates for margin trading.

Long and short positions are two poles of a strategic approach to margin trading. The choice between them depends solely on the trader’s analysis and market forecast.
