# Trading

OptSwap provides users with a number of tools to trade quickly and efficiently on-chain. It is important to understand how each of them works so that the various advanced order types and settings can be utilized correctly.

In general, all limit orders and trades are always matched on the Decentralized Exchange (DEX). The Automated Market Maker (AMM) manages orders on your behalf by constantly re-pricing the options contracts based on your pre-defined risk criteria until a counterparty is available who is willing to trade at the latest price.

Batch Orders allow traders to post multiple orders as part of a single transaction; and can ensure that all orders within the batch are either completely filled or the whole batch gets reverted. This is useful for option spread traders who want to be guaranteed the complete fill of all the legs within an advanced multi-legged strategy.

Buying options requires paying the premium denominated in cash tokens. Selling options requires posting the margin, which may be denominated in either the underlying asset or cash tokens depending on the option type. Spreads are always cash settled.
