Teaser

Hold assets with positive trailing return; equal-weight the winners. Universe: BTC-USD, ETH-USD. Parameters: lookback=252; rebalance=monthly. Rebalanced on the engine's template schedule with 5 bps commission and 2 bps slippage.

Strategy in a nutshell

The purpose of the article is to identify the determinants of cryptocurrency returns. To achieve this goal, the article presents an attempt to create factors that reflect the characteristics of the cryptocurrency market, and uses Fama–French type multifactor models for analyzing the returns of cryptocurrencies. Standard factors based on capitalization indicators, cryptocurrency trading volumes and the third momentum were built. The paper also presents an estimation of the impact of these factors on various groups, or portfolios, of cryptocurrencies in certain periods of time (the period of market formation and the period of high price volatility of the market, including its division into two sub-periods: before the coronavirus pandemic and during the pandemic), which allows us to consider

Economic rationale

Positive time-series momentum indicates a favorable trend state; holding only assets with positive trailing returns tilts toward that premium.

Entry & exit

Entry

On each month, compute 252-day total return on BTC-USD, ETH-USD. Hold only names with positive absolute momentum, equal-weight.

Exit

Sell a name when its trailing 252-day return turns non-positive. If none remain positive, sit in cash.

Market data required

Needs at least 252 adjusted daily closes on BTC-USD, ETH-USD before the first signal is ready. Crypto columns include weekend rows. The lab loads Yahoo Finance via backtest.data.load_daily_prices.

Symbols

BTC-USD, ETH-USD

Frequency

Monthly · Daily adjusted close; signals rebalance on the month change (last available session)

History needed

≥ 252 trading days per symbol (about 12 months), plus a few extra bars so the first signal can fire.

Fields

Adjusted close (Yahoo auto_adjust)
Session date index

Credentials

None for paper and the onsite lab
Broker or exchange API keys only for live orders

APIs & providers

Quant Buffet Data API

The lab calls load_daily_prices for the ASSETS panel of adjusted closes, then caches CSV so backtests replay the same series.

Provider: backtest.data.load_daily_prices
Auth: None for paper / sandbox backtests
Endpoints: load_daily_prices(ASSETS, start="2000-01-01")

API / docs → /en/docs/data-api

Yahoo Finance via yfinance

ETFs and crypto proxies such as BTC-USD / ETH-USD share Yahoo daily bars (auto_adjust=True).

Provider: yfinance → Yahoo Finance
Auth: None for public history
Endpoints: 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.

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}

    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})
