导读

投资标的：BTC-USD、ETH-USD。再平衡：每月。Universe: BTC-USD, ETH-USD. Parameters: rebalance=monthly.

策略概要

该策略投资于 BTC-USD、ETH-USD，仅在价格高于 200 日均线时等权做多，否则持有现金，并按月再平衡。论文用固定均线规则检验 BTC/AUD、BTC/EUR、BTC/JPY、BTC/ZAR（2010-06-19 至 2020-10-30）的实际收益与动态 CAPM 均衡收益，判断技术分析能否跑赢买入持有。

经济逻辑

相关证据来自“技术交易规则盈利与加密汇率的动态风险溢价”：时变风险溢价可能解释表面上的技术分析超额收益；在新兴市场汇率中，均线规则仍常显示盈利。

入场与出场

入场

每月检查 BTC-USD, ETH-USD。收盘价高于 200 日均线的标的等权做多；若无一合格则空仓。空仓（目标权重为空字典）等于 100% 现金。

出场

下一再平衡日收盘价跌破 200 日均线即剔除该标的。全部跌破均线时组合转为现金。引擎按 5 bps 佣金 + 2 bps 滑点成交。

所需行情数据

需要 BTC-USD, ETH-USD 至少 200 根复权收盘价，才能形成第一个有效信号。加密货币列为日历日（含周末）。实验室通过 backtest.data.load_daily_prices 读取 Yahoo Finance。

标的

BTC-USD, ETH-USD

频率

每月 · 日频复权收盘价；信号按月再平衡（用当月最后一个有效交易日）

所需历史

每个标的至少 200 根交易日 K 线（约 10 个交易月），外加数根缓冲才能发出第一个信号。

字段

复权收盘价（Adj Close / auto_adjust Close）
交易日日期索引

凭证

回测与实验室：无需密钥
实盘下单才需要券商 / 交易所 API

API 与数据源

Quant Buffet 数据 API

实验室用 load_daily_prices 拉取 ASSETS 的复权收盘价面板，磁盘缓存后回测可复现。

提供方: backtest.data.load_daily_prices
鉴权: 回测无需密钥
接口: load_daily_prices(ASSETS, start="2000-01-01")

API / docs → /zh/docs/data-api

Yahoo Finance（yfinance）

ETF 与 BTC-USD / ETH-USD 等加密代理共用 Yahoo 日线（auto_adjust=True）。

提供方: yfinance → Yahoo Finance
鉴权: 公开历史无需密钥
接口: Ticker.history / yf.download(auto_adjust=True)

Quant Buffet syntax cheat sheet (copy / insert)

Paste these fragments into the editor. The sandbox rejects QuantConnect, os, and network libraries.

Required imports

Only these libraries are allowed in the sandbox.

from __future__ import annotations

import numpy as np
import pandas as pd

from backtest.data import load_daily_prices
from backtest.engine import EngineConfig, PortfolioEngine
from backtest.metrics import compute_metrics

ASSETS list (whitelisted ETFs)

Module-level list. Tickers must be in the Quant Buffet whitelist.

ASSETS = ["SPY", "QQQ", "TLT", "GLD", "BIL"]

make_on_day contract

Must return (on_day, ready). on_day calls engine.set_target_weights.

def make_on_day(prices: pd.DataFrame):
    cols = [c for c in ASSETS if c in prices.columns]
    sma = prices[cols].rolling(200, min_periods=200).mean()
    state = {"last": None}

    def on_day(engine: PortfolioEngine, dt: pd.Timestamp) -> None:
        if sma.loc[dt].isna().all():
            return
        key = (dt.year, dt.month)
        if state["last"] == key:
            return
        state["last"] = key
        long = [

        ]
        weights = {} if not long else {s: 1.0 / len(long) for s in long}
        engine.set_target_weights(dt, weights)

    ready = sma.dropna(how="all").index.min() if sma.notna().any().any() else None
    return on_day, ready

Set target weights

Weights should sum to about 1.0. Empty dict = 100% cash.

engine.set_target_weights(dt, {"SPY": 0.60, "BIL": 0.40})
