Workflow

工作流程

  1. Identify legs — extract each leg: side (buy/sell), type (call/put), strike, expiry, quantity, premium paid/received.
  2. Fetch live data — call 
    longbridge option quote
    for each OCC symbol; if not known, use 
    option chain
    to find it. Fetch underlying spot with 
    longbridge quote
    .
  3. Compute at-expiry payoff for each leg:
    • Long call: 
      max(S − K, 0) − premium
    • Short call: 
      premium − max(S − K, 0)
    • Long put: 
      max(K − S, 0) − premium
    • Short put: 
      premium − max(K − S, 0)
    • Net payoff = sum across all legs.
  4. Find breakeven(s) — stock price(s) where net payoff = 0.
  5. Find max profit and max loss — scan payoff at key price points (strikes + beyond).
  6. Summarise Greeks from 
    option quote
    output; compute net Greeks for multi-leg.
  7. Output payoff table + summary (template below).
  1. 识别头寸腿 — 提取每条腿的信息：方向（买/卖）、类型（认购/认沽期权）、行权价、到期日、数量、支付/收到的权利金。
  2. 获取实时数据 — 为每个OCC合约代码调用
    longbridge option quote
    ；若合约代码未知，使用
    option chain
    查找。通过
    longbridge quote
    获取标的现货价格。
  3. 计算到期时的盈亏：
    • 认购期权多头：
      max(S − K, 0) − premium
    • 认购期权空头：
      premium − max(S − K, 0)
    • 认沽期权多头：
      max(K − S, 0) − premium
    • 认沽期权空头：
      premium − max(K − S, 0)
    • 净盈亏 = 所有头寸腿的盈亏之和。
  4. 查找盈亏平衡点 — 净盈亏为0时的股票价格。
  5. 查找最大盈利和最大亏损 — 扫描关键价格点（行权价及以外）的盈亏情况。
  6. 汇总Greeks数据 — 从
    option quote
    输出中提取；计算多腿头寸的净Greeks。
  7. 输出结果 — 盈亏表格 + 总结（模板如下）。
