以下为不同市场环境下常见的期权策略介绍，仅供教育性参考，不构成操作建议。

| Market view | IV level | 常见策略参考 / Common strategy reference | Risk profile | |---|---|---|---| | Bullish | Any | Long call / bull call spread | Limited loss, capped or unlimited gain | | Bullish | Rich | Bull put spread (sell put spread) | Collect premium, limited risk | | Bearish | Any | Long put / bear put spread | Limited loss, capped or large gain | | Bearish | Rich | Bear call spread (sell call spread) | Collect premium, limited risk | | Neutral (range-bound) | Rich | Short strangle / short straddle | Collect premium, unlimited risk | | Neutral (range-bound) | Rich | Iron condor | Collect premium, defined risk both sides | | Neutral (vol expansion) | Cheap | Long straddle / long strangle | Pay premium, profit from large move | | Income on holding | Any | Covered call | Reduce cost basis, cap upside | | Downside protection | Any | Protective put | Insurance premium, preserve upside |

Workflow

1. Clarify user's market view (direction + conviction) and time horizon.
2. Fetch underlying spot (longbridge quote), option chain expiries, near-term strikes, and call/put volume.
3. Assess IV from ATM IV in chain vs rough HV proxy (see longbridge-options-volatility).
4. Select 1–2 strategies from the matrix; explain structure, legs, and cost.
5. Show example legs using live strikes from the chain (ATM and nearby).
6. Output structured recommendation (template below).
