Beginner's Quick Guide to Long and Short Contract Operations

1. Analysis of Short Selling and Short Selling Mechanisms#

Short Selling: Holding a bearish outlook on market trends
Short Selling Strategy: A trading strategy implemented based on a bearish judgment. Direct short selling is not possible in the spot market and must be achieved through futures contracts or leveraged trading.

Principle of Short Selling Operations:
Investors believe that the current coin price is overvalued and predict a future decline. They arbitrage through the "borrow first, sell later - buy back at a low price" model:

  1. Borrow and sell digital assets at the current high price
  2. Buy back at a low price after the coin price drops
  3. Earn the price difference (interest on borrowing must be deducted)

Practical Case:
A certain token is currently priced at 10 yuan, and the investor pledges 2 yuan as margin to borrow 1 unit of the token:

  • Immediately sell to obtain 10 yuan (funds in a frozen state)
  • If the coin price drops to 5 yuan, use 5 yuan to buy back and return
  • After unfreezing the funds, net profit of 5 yuan (interest not accounted for)
  • If the coin price rises to 15 yuan, additional margin must be provided, or liquidation will occur

2. Detailed Explanation of Bullish and Long Strategies#

Bullish: Holding a bullish outlook on market trends
Long Strategy: A basic trading strategy to obtain profit from price differences through "buy low, sell high"

Bullish Operation Model:
Investors are optimistic about the asset's appreciation potential and execute the "buy at current price - sell at high price" strategy:

  1. Buy the target asset at the current price
  2. Sell at an opportune time after the price rises
  3. Achieve capital appreciation

Practical Case:
Establish a position by buying when SOL is priced at 140U:

  • Close the position when the price rises to 280U
  • Achieve a 100% return (140U profit)

Note: Both bulls and bears are not specific individuals but a collective of investors with similar market expectations.

Core Summary:

  • Long: Expectation of rise → Build position at low price → Close position at high price
  • Short: Expectation of decline → Borrow coins and sell → Buy back at low price
  • Bull: Market participants with a bullish outlook
  • Bear: Market participants with a bearish outlook
