Use expected move and IV context before choosing a structure.
Use the yield tool to stop headline premium from misleading you.
Fit the trade to a risk budget before you think about "just one more contract".
Approximate one-standard-deviation move based on spot price, implied volatility, and days to expiry.
Compare option income with the capital it actually ties up.
Translate a risk budget into a contract count.
