# Options principles

## When to use

- The question is how options work, not which contract to trade.
- A later playbook needs a shared vocabulary: calls, puts, debit versus credit, defined versus undefined risk.

## Setup

- Use {symbol} as the placeholder and replace it with the ticker that was named.
- Single-leg: buy or sell one call or one put.
- Multi-leg: vertical spreads, iron condors, butterflies, straddles, strangles, calendars, and diagonals.
- State the outlook the structure expresses (bullish, bearish, or range) without turning it into an instruction to trade.

## Rules of thumb

- Name time decay (theta) and volatility (vega) when they drive the example.
- Long options can expire worthless. The premium paid is the defined loss.
- A naked short call has undefined risk. Do not present it as a routine structure.
- Mention assignment and early exercise when a short option is part of the example.

## Pitfalls

- Shortening or skipping the disclosure.
- A payoff sketch treated as a forecast.
- Examples that ignore commissions, fees, margin, interest, and taxes.
- Mixing a single long option with a spread and calling both the same risk.

## Disclaimer

Options involve risks and are not suitable for everyone. Individuals should not enter into options transactions until they have read and understood the options disclosure document, *Characteristics and Risks of Standardized Options*, available at OptionsEducation.org or from your broker or the Options Clearing Corporation. Commissions, fees, margin, interest, and taxes affect outcomes and are not included in examples. These explanations are illustrative education. They are not a signal, an endorsement, a recommendation, or a solicitation to buy or sell. Past performance is not indicative of future results. All content of that disclosure document is from the Options Clearing Corporation.
