Hyperliquid Perps & Spot

Hyperliquid永续合约与现货

Playbook for trading perpetuals and spot on Hyperliquid through OpenFinance, plus the real-time WebSocket for market data.

本指南介绍如何通过OpenFinance在Hyperliquid上进行永续合约与现货交易，以及获取实时WebSocket市场数据。

Prerequisite

前置条件

User completed
```
openfin-setup
```
(API key + EVM wallet delegation).
For trading: USDC in the user's wallet, then deposit USDC into the Hyperliquid account via
```
GET /agent/trading/deposit-address
```
(send USDC to that deposit address; chain routing is handled automatically).
For perp orders specifically: margin must be in the perp account, not spot. Transfer with
```
POST /agent/trading/transfer
```
.

用户已完成
```
openfin-setup
```
（API密钥 + EVM钱包授权）。
交易前：钱包中需有USDC，然后通过
```
GET /agent/trading/deposit-address
```
获取Hyperliquid账户的存款地址（向该地址发送USDC；链上路由将自动处理）。
永续合约订单专属要求：保证金必须在永续账户中，而非现货账户。可通过
```
POST /agent/trading/transfer
```
进行划转。

Historical candles (OHLCV)

历史K线（OHLCV）

Not a backend route — hit Hyperliquid's info endpoint directly:

http

POST https://api.hyperliquid.xyz/info
Content-Type: application/json

{
  "type": "candleSnapshot",
  "req": {
    "coin": "BTC",
    "interval": "1h",              // 1m,3m,5m,15m,30m,1h,2h,4h,8h,12h,1d,3d,1w,1M
    "startTime": 1706659200000,    // ms
    "endTime": 1706745600000       // ms, optional (defaults to now)
  }
}

Returns up to 5000 most recent candles. For HIP-3 spot tokens, prefix the coin with the dex name, e.g.

"xyz:XYZ100"

此功能并非后端路由——需直接调用Hyperliquid的info端点：

http

POST https://api.hyperliquid.xyz/info
Content-Type: application/json

{
  "type": "candleSnapshot",
  "req": {
    "coin": "BTC",
    "interval": "1h",              // 1m,3m,5m,15m,30m,1h,2h,4h,8h,12h,1d,3d,1w,1M
    "startTime": 1706659200000,    // 毫秒
    "endTime": 1706745600000       // 毫秒，可选（默认当前时间）
  }
}

最多返回5000根最新K线。对于HIP-3现货代币，需在币种名称前添加DEX前缀，例如

"xyz:XYZ100"

。

Market data (WebSocket)

市场数据（WebSocket）

Hyperliquid exposes a real-time feed at

wss://api.hyperliquid.xyz/ws

Subscribe message shape:

json

{ "method": "subscribe", "subscription": { "type": "<channel>" } }

Common channels:

```
allDexsAssetCtxs
```
— funding rate, mark price, OI, 24h volume per asset
```
allMids
```
— real-time mid prices for every coin
```
l2Book
```
(
```
{type, coin: "BTC"}
```
) — orderbook updates
```
trades
```
(
```
{type, coin}
```
) — trade tape
```
candle
```
(
```
{type, coin, interval: "1m"}
```
) — streaming candles
```
orderUpdates
```
/
```
userFills
```
/
```
userFundings
```
— user-scoped; requires signing

Hyperliquid提供实时数据流，地址为

wss://api.hyperliquid.xyz/ws

。

订阅消息格式：

json

{ "method": "subscribe", "subscription": { "type": "<channel>" } }

常用频道：

```
allDexsAssetCtxs
```
—— 每个资产的资金费率、标记价格、持仓量、24小时交易量
```

Backend-managed WS

后端管理的WebSocket

The OpenFinance backend keeps one shared connection to

wss://api.hyperliquid.xyz/ws

and caches the latest snapshot per channel. Use this when multiple agents share the backend and you want a single connection + consistent state. MCP tools:

```
subscribe_all_dexs_asset_ctxs
```
— start the shared backend subscription
```
unsubscribe_all_dexs_asset_ctxs
```
— stop it
```
get_all_dexs_asset_ctxs
```
— read the latest cached snapshot
```
get_ws_status
```
— is the backend's connection alive

⚠ The

allDexsAssetCtxs

array has no asset names — each entry maps by index to the

universe

from

GET /agent/trading/market/metas

. Call

/market/metas

at least once to build the index→name map.

OpenFinance后端保持一个与

wss://api.hyperliquid.xyz/ws

的共享连接，并缓存每个频道的最新快照。当多个Agent共享后端且需要单一连接+一致状态时使用此方式。MCP工具：

```
subscribe_all_dexs_asset_ctxs
```
—— 启动后端共享订阅
```
unsubscribe_all_dexs_asset_ctxs
```
—— 停止订阅
```
get_all_dexs_asset_ctxs
```
—— 读取最新缓存快照
```
get_ws_status
```
—— 查询后端连接是否存活

⚠

allDexsAssetCtxs

数组不包含资产名称——每个条目通过索引与

GET /agent/trading/market/metas

返回的

universe

对应。需至少调用一次

/market/metas

来构建索引→名称的映射。

Direct WS from the client

客户端直接连接WebSocket

For reactive UIs or per-client streams, open your own WS to

wss://api.hyperliquid.xyz/ws

and subscribe. Don't expect the backend's cache to reflect connections that weren't opened through it.

对于响应式UI或客户端专属流，可自行打开WebSocket连接至

wss://api.hyperliquid.xyz/ws

并订阅。此时后端缓存不会反映非通过其建立的连接状态。

Orders

订单

Placing orders

下单

POST /agent/trading/orders
— Place one or more orders. Each order needs
```
a
```
(asset index from
```
perp-metas

```
(price as string),
```
s
```
(size as string),

Grouping:
```
"normalTpsl"
```
groups take-profit/stop-loss child orders with a primary;
```
"positionTpsl"
```
attaches them to an existing position. Fetch market metas first to get correct asset indices and szDecimals.

POST /agent/trading/orders
—— 下达一个或多个订单。每个订单需要
```
a
```
（来自
```
perp-metas
```
的资产索引）、
```
b
```
（true=买入）、
```
p
```
（价格字符串）、
```
s
```
（数量字符串）、

```
  —— 取消前有效（挂单限价）
- ```
"Ioc"
```
  —— 立即成交或取消（类市价；穿透订单簿成交）
- ```
"Alo"
```
  —— 仅增加流动性（仅挂单；若将成为吃单者则拒绝）
分组：
```
"normalTpsl"
```
将止盈/止损子订单与主订单分组；
```
"positionTpsl"
```
将其附加至现有持仓。下单前需先获取市场元数据以获取正确的资产索引和szDecimals。

Hyperliquid rejects prices too far from mid (price bands, ~5-10%). For aggressive fills cross the book but stay in-band.

规范。
Hyperliquid会拒绝与中间价偏差过大的价格（价格区间约5-10%）。若要激进成交，可穿透订单簿但需保持在价格区间内。

Cross margin: all positions share one margin pool. Default.
