Understanding Sell to Close in Options Trading
Sell to close refers to the process of exiting an options trade by selling a contract you currently own. This action effectively closes your existing long position in the market.
Key Characteristics of Sell to Close:
- Used to exit positions originally opened with "buy to open" orders
- Common in derivatives trading but also applicable to equities and fixed-income
- Allows traders to realize profits or cut losses before expiration
- Often contrasted with "buy to close" and "sell to open" strategies
How Sell to Close Works in Practice
When traders own options contracts, they have three potential exit strategies:
- Letting the option expire worthless (if out of the money)
- Exercising the contract (if in the money)
- Selling to close the position (regardless of moneyness)
