Options Risk Management Basics

Good strategy selection without risk management is incomplete. Size for survival, not for the best-case payoff diagram.

Defined vs undefined risk

• Defined risk — max loss known at entry (long options, debit/credit verticals with long wings, iron condors, butterflies).
• Undefined / large risk — naked calls, naked puts, short straddles/strangles without wings. Require experience, margin, and strict sizing.

Position sizing ideas

• Risk only a small fraction of portfolio equity on any single trade’s max loss.
• For credit structures, size off max loss (width − credit), not just credit received.
• Correlated underlyings stack risk — many “different” tickers can move together.

Plan exits

Decide in advance: profit target (e.g. 50% of max credit), time stop (e.g. close by 21 DTE), or invalidation level on the chart. Hoping through assignment week is not a plan.

Use the calculator as a risk tool

1. Enter realistic premiums from the chain (mid or worse fill).
2. Check max loss and breakevens at expiration.
3. Scan the heatmap for ugly regions before expiry (especially multi-expiry trades).
4. Stress strikes wider/narrower and see how risk changes.
