看得眼花繚亂。這個計策比writeCC好是把向上的覆蓋率提高了

For writing CC at $150 (premium $4.50):

• f NVDA stays below $150: You keep the premium, and your shares.

• If NVDA rises above $150: Your shares are called away at $150, and you keep the premium. Your total gain = ($150 − $142) × 100 + $450 = $1250.

• If NVDA goes to $160+: Your upside is capped at $150 + premium = $154.50 effective sale price. You miss gains above that. 

下麵是蝴蝶部分的分析（AI 提供）

To avoid the open-ended risk above $165, consider:

• 1× Buy @ $150

• 2× Sell @ $160

• 1× Buy @ $170
