# How a match works

> Long, short, damage and knockouts.

Every match is a fight on a live chart. You and your opponent trade the same price, and every trade you close in profit lands as a hit.

## Controls

| Button    | What it does                                    | Web key |
| --------- | ----------------------------------------------- | ------- |
| **Long**  | Opens a trade that gains if the price goes up   | `L`     |
| **Short** | Opens a trade that gains if the price goes down | `S`     |
| **Close** | Closes your trade                               | `C`     |

## Damage

* A trade you close in profit damages your opponent.
* A trade you close at a loss damages you. Very small losses don't.
* While a trade is in profit its multiplier climbs, so letting a winner run hits harder.

## Rounds

* A match has three short rounds, and health resets at the start of each one.
* Open trades close automatically when a round ends.
* The player with more health takes the round.

## Knockouts

A knockout happens when a winning close takes your opponent's health to zero on a big enough price move, and it ends the match at once. Cards can't knock anyone out, and knockouts can't happen in the opening seconds of a round.

A player can sit at zero health without being knocked out. They then lose the round on health.

## Winning

The player who wins more rounds wins the match. If that's level, total score decides, then health, and draws are possible. The result screen shows how it ended: **by KNOCKOUT**, **on points** or **by forfeit**.

## Cards

In **In-Game Cards** matches you also play power-up cards. See [Cards and decks](/play/cards).
