Options Trading 101
Calls, puts, the Greeks, and common strategies — the building blocks every options trader needs to understand.
What Are Options?
An option is a financial contract that gives you the right, but not the obligation, to buy or sell an underlying asset at a specific price (the strike price) before a certain date (the expiration date). If you are new to the markets, start with our trading basics guide first.
Options are powerful because they allow you to:
- Profit from price movements with less capital than buying stock directly
- Generate income by selling options and collecting premium
- Hedge existing positions against adverse price moves
- Define your exact maximum risk before entering a trade
Key Terminology
- Premium
- The price you pay to buy an option, or the price you receive when you sell one. This is the option's market price.
- Strike Price
- The price at which the option allows you to buy (call) or sell (put) the underlying asset.
- Expiration Date
- The last day the option is valid. After this date, the option ceases to exist. 0DTE options expire on the same day they are traded.
- In-the-Money (ITM)
- A call is ITM when the stock price is above the strike price. A put is ITM when the stock price is below the strike price. ITM options have intrinsic value.
- Out-of-the-Money (OTM)
- The opposite of ITM. A call is OTM when the stock price is below the strike price. OTM options have only time (extrinsic) value.
- At-the-Money (ATM)
- When the stock price is very close to the strike price.
Calls vs. Puts
There are two types of options, and each can be bought or sold:
Call Option
Right to: Buy
Buyer bias: Bullish
Seller bias: Bearish / Neutral
Profit when the price goes up. The higher above the strike, the more the call is worth.
Put Option
Right to: Sell
Buyer bias: Bearish
Seller bias: Bullish / Neutral
Profit when the price goes down. The further below the strike, the more the put is worth.
Buyers vs. Sellers
Every options trade has a buyer and a seller. Their roles and risk profiles are very different:
| Buyer (Long) | Seller (Short) | |
|---|---|---|
| Pays/Receives | Pays premium (debit) | Receives premium (credit) |
| Max Loss | Limited to premium paid | Can be substantial (unless spread) |
| Max Profit | Potentially unlimited (calls) | Limited to premium received |
| Time Decay | Works against you | Works in your favor |
The Greeks
The Greeks are measurements that describe how an option's price changes in response to various factors. Understanding them is essential for managing options positions.
Delta
Measures: $1 price change
A delta of 0.30 means the option gains $0.30 for every $1 the stock moves. Calls = positive, puts = negative.
Gamma
Measures: Delta change rate
High gamma = delta changes rapidly. Foundation of GEX analysis — tells us how market makers hedge.
Theta
Measures: Daily time decay
Theta of −0.50 = loses $0.50/day. Accelerates near expiration — why 0DTE selling works.
Vega
Measures: 1% IV change
High vega = very sensitive to volatility swings. Rising VIX generally increases all option premiums.
Options Pricing
An option's price (premium) has two components:
Intrinsic Value
The amount the option is in-the-money. A call with a strike of 6000 when SPX is at 6050 has $50 of intrinsic value. Out-of-the-money options have zero intrinsic value.
Extrinsic (Time) Value
Everything beyond intrinsic value. This is the "hope" premium — the chance that the option could become more valuable before expiration. Extrinsic value is influenced by:
- Time to expiration — More time = more extrinsic value
- Implied volatility — Higher volatility = more extrinsic value
- Distance from the money — ATM options have the most extrinsic value
Common Strategies
Rather than buying or selling single options, most traders use spreads — combinations of options that define both maximum risk and maximum reward.
Credit Spread (Vertical Spread)
Sell one option and buy another at a different strike, same expiration. You collect a net credit. If the underlying stays away from your sold strike, you keep the credit as profit.
Bull put credit spread payoff at expiration: max profit when price stays above the short put strike, max loss when price falls below the long put strike.
- Bull Put Spread bullish — Sell a put, buy a lower-strike put. Profit if price stays above your sold strike.
- Bear Call Spread bearish — Sell a call, buy a higher-strike call. Profit if price stays below your sold strike.
Iron Condor (IC)
A combination of a bull put spread and a bear call spread. You collect credit from both sides, creating a "profit zone" between the two sold strikes. Best used when you expect the market to stay range-bound.
Bear Call Spread (above) Sell 6080C / Buy 6100C
─────────────────────────────────────────────────
SPX Price: 6050
─────────────────────────────────────────────────
Bull Put Spread (below) Sell 6020P / Buy 6000P
Iron Fly (IF)
Like an Iron Condor, but the sold call and sold put share the same strike (at-the-money). Collects more premium than an Iron Condor but has a narrower profit zone. Best used when you expect the market to pin at a specific level — exactly what GEX analysis can predict.
Directional Spreads
When the market has a clear direction, IntelliTrade uses directional spreads:
- Put Spread (bullish) — Used in positive GEX regimes when the market bias is upward
- Call Spread (bearish) — Used in negative GEX regimes when the market bias is downward
