# Long/Short

## Long – Buy Call Option

When you believe a token’s price will rise, you can pay a premium to go Long.

**What You do:**

* Open a Long Position
* Pay the premium (in tokens)<br>

**P\&L before maturity:**

* 📈 Current Price > Strike Price → Profit is obtained through **Exercise – Net Settle or Exercise – Delivery**.
* 📉 Current Price < Strike Price → Loss limited to premium; you may “Close Position” early to stop losses (the remaining premium will be settled in tokens)

## Short – Buy Put Option

When you believe a token’s price will fall, you can pay a premium to go Short.

**What You do:**

* Open a Short Position
* Pay the premium (in USDT)<br>

**P\&L before maturity:**

* 📉 Current Price < Strike Price → Profit is obtained through **Exercise – Net Settle or Exercise – Delivery**.
* 📈 Current Price > Strike Price → Loss limited to premium; you may “Close Position” early to stop losses (the remaining premium will be settled in USDT).

**Risk Warning:**

**Market liquidity is not guaranteed.** Closing a Long/Short position early requires a counterparty. In low-liquidity conditions, you may be unable to unwind your position or may suffer significant price impact (slippage) to execute the trade. Please ensure you are comfortable with the associated risks before trading.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.ts.finance/protocol-mechanisms/alpha-market/long-short.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
