About Option Payoff Diagrams

Option payoff diagrams help traders visualize the potential profit or loss of an option strategy at expiration across a range of underlying prices. These diagrams are essential tools for option traders to understand risk, identify break-even points, and optimize strategies.

Understanding the Diagram

  • X-axis: Represents the potential price of the underlying asset at expiration
  • Y-axis: Shows the potential profit or loss of the strategy
  • Break-even point(s): Where the line crosses the x-axis (zero profit/loss)
  • Max profit/loss: The highest and lowest points on the payoff line

Popular Option Strategies

  • Directional Strategies: Long Call/Put, Bull/Bear Spreads - Profit from price movement in a specific direction
  • Volatility Strategies: Straddles, Strangles - Profit from significant price movement in either direction
  • Income Strategies: Covered Calls, Cash-Secured Puts - Generate income through premium collection
  • Defined Risk Strategies: Iron Condors, Butterflies - Limit risk while targeting specific price ranges

交易提示

風險管理

Always define your maximum acceptable loss before entering a position. Consider the worst-case scenario shown in the payoff diagram and ensure it aligns with your risk tolerance.

Strategy Selection

Choose strategies that align with your market outlook. Bullish strategies profit when prices rise, bearish when prices fall, and neutral when prices remain stable.

Break-even Analysis

Pay close attention to break-even points, as they define the price range where your strategy begins to profit. Wider break-even ranges often provide more flexibility.

Probability Assessment

Consider the likelihood of reaching your profit target. An attractive payoff with a low probability of success may not be as valuable as a modest payoff with higher probability.

本工具計算什麼

繪製期權持倉在到期日、不同正股價格下的盈虧圖。

公式
買入認購損益 = max(S − K, 0) − 期權金；買入認沽 = max(K − S, 0) − 期權金
計算示例
以 5 元買入行使價 100 的認購期權，105 為打和點；正股低於 100 則損失全部 5 元。
何時使用
建立多腿組合前，先看清損益形態。
常見錯誤
此圖只反映到期日情況。到期前受時間值及波幅影響，持倉甚少落在該線上。
