1. Iron Condor

Structure:
- Sell 1 out-of-the-money (OTM) call.
- Buy 1 further out-of-the-money (FOTM) call.
- Sell 1 out-of-the-money (OTM) put.
- Buy 1 further out-of-the-money (FOTM) put.

Profit and Risk:

Profit: The maximum profit is limited to the net credit received from the premiums of the sold options, and it is realized when the underlying asset stays between the two strike prices of the sold call and put.

Risk: The maximum risk is limited to the difference between the strike prices of either the calls or puts, minus the net premium received.

Best for:
Low-volatility environments where the underlying asset is expected to remain within a narrow trading range.

2. Butterfly Spread

Structure:
- Buy 1 lower-strike call (or put).
- Sell 2 at-the-money (ATM) calls (or puts).
- Buy 1 higher-strike call (or put).

Profit and Risk:

Profit: The maximum profit is achieved if the underlying asset’s price is at the middle strike price (the sold options) at expiration. The profit is limited to the difference between the two outer strike prices minus the net premium paid.

Risk: The maximum loss is limited to the initial net debit paid to establish the position.

Best for:
Traders with a neutral outlook on the underlying asset, expecting minimal price movement around the current market price.

3. Calendar Spread

A Calendar Spread (also known as a Time Spread) involves buying and selling options of the same type (call or put) with the same strike price but different expiration dates.

Structure:
- Buy 1 longer-term call (or put) option.
- Sell 1 shorter-term call (or put) option at the same strike price.

Profit and Risk:
Profit: Maximum profit occurs if the underlying asset remains near the strike price of the sold option at expiration. The strategy benefits from the faster time decay of the short-term option.
- **Risk:** The risk is limited to the net debit paid to establish the spread.

**Best for:**
- Traders expecting low volatility in the short term but a more significant move in the longer term.

4. Iron Butterfly

Structure:
- Sell 1 at-the-money (ATM) call.
- Sell 1 at-the-money (ATM) put.
- Buy 1 out-of-the-money (OTM) call.
- Buy 1 out-of-the-money (OTM) put.

Profit and Risk:
Profit: The maximum profit is achieved when the underlying asset is exactly at the strike price of the sold options at expiration, capturing the full premium received.
Risk: The maximum risk is limited to the difference between the strike prices of the calls or puts, minus the net premium received.

Best for:

Traders with a strong conviction that the underlying asset will not move significantly in either direction.

5. Straddle and Strangle

Straddle Structure:
- Buy 1 at-the-money (ATM) call.
- Buy 1 at-the-money (ATM) put.

Strangle Structure:
- Buy 1 out-of-the-money (OTM) call.
- Buy 1 out-of-the-money (OTM) put.

Profit and Risk:
Profit: Both strategies profit from large price movements in either direction. A Straddle is more aggressive, while a Strangle is less expensive but requires a more substantial move for profitability.

Risk: The maximum loss for both is limited to the total premium paid.

Best for:
Situations where high volatility is expected, such as earnings reports or significant news events.

6. Ratio Spread

Structure:
Buy 1 call (or put) option.
Sell 2 or more calls (or puts) at a different strike price (usually closer to the current market price).

Profit and Risk:

Profit: The strategy profits if the underlying asset moves in a particular direction but stays within a certain range.

Risk: The risk can be unlimited if the underlying moves significantly against the position, especially with uncovered sold options.

Best for:
Traders with a specific directional bias but who are also looking to reduce the initial cost of the position.

7. Condor Spread

Structure:
- Buy 1 lower-strike call (or put).
- Sell 1 lower-middle-strike call (or put).
- Sell 1 higher-middle-strike call (or put).
- Buy 1 higher-strike call (or put).

Profit and Risk:
Profit: The maximum profit is achieved when the underlying asset’s price is between the middle strike prices at expiration.
Risk: The maximum loss is limited to the initial debit paid to establish the position.

Best for:
Traders expecting low volatility but seeking a lower-risk profile than the Butterfly Spread.
