作为一名在加密货币量化领域深耕多年的工程师,我今天要分享一个让很多量化团队头疼的问题:如何高效获取 Deribit 期权 orderbook 快照数据并进行回测。在正式开讲之前,先让我用一组真实数字说明为什么我选择使用 HolySheep AI 作为主力 LLM 供应商。
先算一笔账:LLM 成本对比与节省测算
让我们先用 2026 年 5 月最新官方 output 价格做个横向对比:
| 模型 | 官方 Output 价格 | HolySheep 结算价 | 节省比例 |
|---|---|---|---|
| GPT-4.1 | $8.00/MTok | ¥8.00/MTok | 85%+ |
| Claude Sonnet 4.5 | $15.00/MTok | ¥15.00/MTok | 85%+ |
| Gemini 2.5 Flash | $2.50/MTok | ¥2.50/MTok | 85%+ |
| DeepSeek V3.2 | $0.42/MTok | ¥0.42/MTok | 85%+ |
HolySheep 按 ¥1=$1 结算,而官方汇率为 ¥7.3=$1。这意味着什么?
假设你每月消耗 100 万 token output:
- 使用 DeepSeek V3.2:官方 $420 ≈ ¥3066,HolySheep 仅需 ¥420,节省 ¥2646/月
- 使用 Gemini 2.5 Flash:官方 $2500 ≈ ¥18250,HolySheep 仅需 ¥2500,节省 ¥15750/月
- 使用 Claude Sonnet 4.5:官方 $15000 ≈ ¥109500,HolySheep 仅需 ¥15000,节省 ¥94500/月
对于需要处理海量市场数据的量化团队来说,这个差距意味着每年可以节省数万甚至数十万的 LLM 调用成本,而这些钱完全可以投入到更好的服务器和策略研发中。
为什么需要 Deribit 期权 Orderbook 快照
Deribit 作为全球最大的加密货币期权交易所,其期权市场深度数据对于以下场景至关重要:
- 波动率曲面建模:通过快照数据计算隐含波动率
- 流动性分析:识别大单支撑/阻力位
- 价差策略回测:验证期权价差策略的可行性
- 希腊字母对冲:实时计算 Delta、Gamma 等敏感度
HolySheep API 的 国内直连延迟 <50ms 特性,对于需要低延迟获取快照的场景非常友好。
获取 Deribit 期权 Orderbook 快照的方法
方法一:WebSocket 实时订阅(推荐用于生产环境)
import asyncio
import json
import websockets
from datetime import datetime
class DeribitOptionBook:
def __init__(self, api_key, api_secret):
self.api_key = api_key
self.api_secret = api_secret
self.ws_url = "wss://test.deribit.com/ws/api/v2"
self.snapshots = []
async def authenticate(self, ws):
auth_params = {
"method": "public/auth",
"params": {
"grant_type": "client_credentials",
"client_id": self.api_key,
"client_secret": self.api_secret
},
"id": 1
}
await ws.send(json.dumps(auth_params))
response = await ws.recv()
return json.loads(response)
async def subscribe_option_book(self, ws, instrument_name):
"""订阅期权 orderbook"""
subscribe_params = {
"method": "private/subscribe",
"params": {
"channels": [f"book.{instrument_name}.none.10.100ms"]
},
"id": 2
}
await ws.send(json.dumps(subscribe_params))
print(f"已订阅 {instrument_name} 的 orderbook")
async def on_message(self, ws, msg):
data = json.loads(msg)
# 过滤 orderbook 快照数据
if 'params' in data and 'data' in data['params']:
book_data = data['params']['data']
snapshot = {
'timestamp': datetime.utcnow().isoformat(),
'instrument': book_data.get('instrument_name'),
'bids': book_data.get('bids', []),
'asks': book_data.get('asks', []),
'type': book_data.get('type'),
'change_id': book_data.get('change_id')
}
self.snapshots.append(snapshot)
# 打印前3档行情
if len(book_data.get('asks', [])) > 0:
best_ask = book_data['asks'][0]
best_bid = book_data['bids'][0]
print(f"[{snapshot['timestamp']}] {snapshot['instrument']} - "
f"Bid: {best_bid[0]} @ {best_bid[1]} | "
f"Ask: {best_ask[0]} @ {best_ask[1]}")
async def run(self, instruments):
async with websockets.connect(self.ws_url) as ws:
# 认证
auth_result = await self.authenticate(ws)
if 'result' in auth_result and auth_result['result']:
print("Deribit 认证成功")
# 订阅多个期权合约
for inst in instruments:
await self.subscribe_option_book(ws, inst)
# 持续接收数据
async for msg in ws:
await self.on_message(ws, msg)
使用示例
if __name__ == "__main__":
# BTC 期权合约示例
btc_options = [
"BTC-27JUN2025-95000-C", # 95000 Call
"BTC-27JUN2025-95000-P", # 95000 Put
"BTC-26SEP2025-100000-C", # 100000 Call
]
client = DeribitOptionBook(
api_key="YOUR_DERIBIT_API_KEY",
api_secret="YOUR_DERIBIT_API_SECRET"
)
asyncio.run(client.run(btc_options))
方法二:REST API 获取历史快照(用于回测)
import requests
import time
from typing import List, Dict
import pandas as pd
class DeribitHistoricalBook:

response = requests.get(
f"{self.BASE_URL}/public/get_order_book",

)
if response.status_code == 200:
return response.json().get('result', {})
else:
raise Exception(f"API 请求失败: {response.status_code}")
def get_all_option_instruments(self, currency: str = "BTC",
expired: bool = False) -> List[str]:
"""获取所有期权合约列表"""
params = {
"currency": currency,
"expired": expired,
"kind": "option"
}
response = requests.get(
f"{self.BASE_URL}/public/get_instruments",
params=params
)
if response.status_code == 200:
instruments = response.json().get('result', [])
return [inst['instrument_name'] for inst in instruments]
return []
def collect_snapshots_for_backtest(self, instruments: List[str],
interval_seconds: int = 60,
duration_minutes: int = 30) -> pd.DataFrame:
"""

Args:

"""
snapshots = []
end_time = time.time() + (duration_minutes * 60)
print(f"开始采集 {duration_minutes} 分钟数据,采样间隔 {interval_seconds}s")
while time.time() < end_time:
for inst in instruments:
try:
book = self.get_option_book_snapshot(inst)
snapshot = {

}
snapshots.append(snapshot)
print(f"✓ {inst}: Bid={snapshot['best_bid']}, Ask={snapshot['best_ask']}")
except Exception as e:
print(f"✗ 获取 {inst} 失败: {e}")
time.sleep(0.5) # 避免 API 限流
time.sleep(interval_seconds - 0.5 * len(instruments))
return pd.DataFrame(snapshots)
使用示例
if __name__ == "__main__":
client = DeribitHistoricalBook()
# 获取可用合约
instruments = client.get_all_option_instruments("BTC")
print(f"发现 {len(instruments)} 个 BTC 期权合约")
# 采集回测数据(测试用 1 分钟)
test_instruments = instruments[:3]
df = client.collect_snapshots_for_backtest(
instruments=test_instruments,
interval_seconds=30,
duration_minutes=1
)
print(f"\n采集完成,共 {len(df)} 条快照")
print(df.head(10))
使用 LLM 分析期权 Orderbook 数据

常见报错排查
错误 1:Deribit API 认证失败 (401 Unauthorized)
# 错误信息
{'error': {'message': 'Invalid credentials', 'code': 13009}}

Deribit 需要先获取 access_token,不能直接用 API Key 认证
正确流程:

适合谁与不适合谁
| 场景 | 适合使用本文方案 | 不适合/需要额外考虑 |
|---|---|---|
| 数据规模 | 每日 <100 万条快照 | 每日 >500 万条快照(需要专业数据管道) |
| 延迟要求 | 亚秒级延迟可接受 | 微秒级超低延迟(需硬件加速/FPGA) |
| 预算 | 希望控制 LLM 成本 85%+ | 有无限预算,追求最低官方价 |
| 技术栈 | Python 为主 | 纯 C++/Rust 高频交易系统 |
| 目标市场 | Deribit 期权 / 国内用户 | 需要 CME Group 等传统交易所数据 |
价格与回本测算
假设一个典型的量化团队使用 LLM 分析期权数据的场景:
| 指标 | 官方 API | HolySheep API | 节省 |
|---|---|---|---|
| 月均 output token | 500 万 (DeepSeek V3.2) | ||
| DeepSeek V3.2 单价 | $0.42/MTok | ¥0.42/MTok | 按 ¥7.3=$1 换算 |
| 月度 LLM 费用 | $2,100 ≈ ¥15,330 | ¥2,100 | ¥13,230/月 |
| 年度 LLM 费用 | ¥183,960 | ¥25,200 | ¥158,760/年 |
