cutebacktests: Historical and Intraday Options Backtesting Runtime

Historical options backtesting, intraday options backtesting, quote-aware backtesting, and walk-forward strategy research for U.S. equities. cutebacktests is the public runtime behind CuteMarkets research: a DuckDB-backed options backtester, a historical options feed, market-data adapters, and an opening-range profile registry that you can run on your own machine.

This repository is designed for developers and quantitative researchers who need more than chart-level ideas. It focuses on causal entry logic, historical contract reconstruction, options microstructure filters, and reproducible evaluation surfaces instead of paper-only strategy descriptions.

• Historical options feed for contract reconstruction and close snapshots
• CuteMarkets-backed market-data access for public examples and default workflows
• Optional compatibility layers for auxiliary providers
• Opening-range profile registry and profile helpers
• Walk-forward and robustness helpers

This repository does not ship the congressional-disclosure engine, live/paper bots, remote server launch tooling, or phase orchestration from the private repo.

Install

python3 -m venv .venv
source .venv/bin/activate
python -m pip install -e '.[dev]'

Configure

cp .env.example .env

Required credentials depend on the commands you run:

• CUTEMARKETS_API_KEY

Optional compatibility workflows may also use:

• ALPACA_API_KEY
• ALPACA_SECRET_KEY

Package-local paths use:

• CUTEBACKTESTS_DATA_DIR
• CUTEBACKTESTS_DB_PATH

Example

from datetime import datetime

from cutebacktests import (
    IntradayOptionsBacktestConfig,
    IntradayOptionsBacktester,
    get_opening_range_profile,
)
from cutebacktests.providers import CuteMarketsProvider
from cutebacktests.settings import Settings
from cutebacktests.storage import DataStore

settings = Settings.from_env(".env")
store = DataStore(settings.db_path)
profile = get_opening_range_profile("c4_long_only_rr15")

try:
    backtester = IntradayOptionsBacktester(
        store=store,
        cutemarkets_provider=CuteMarketsProvider(settings),
    )
    result = backtester.run(
        IntradayOptionsBacktestConfig(
            ticker="SPY",
            start=datetime(2025, 1, 1),
            end=datetime(2025, 1, 31),
            return_trade_log=True,
            **profile.to_intraday_strategy_kwargs(),
        )
    )
    print("trades:", result["trades"])
finally:
    store.close()

If you need an auxiliary provider for a private workflow, the runtime still supports that path. The public examples and the default research path in this repo use CuteMarkets directly.

CLI

Show the public CLI:

python -m cutebacktests.cli --help

Run the intraday/options backtester directly:

python -m cutebacktests.cli run-intraday-options-backtest \
  --ticker SPY \
  --start 2025-01-01 \
  --end 2025-12-31

The public CLI uses CuteMarkets by default. Add --with-alpaca only if you explicitly want the auxiliary provider enabled.

Run a named opening-range profile:

python -m cutebacktests.cli run-opening-range-profile-backtest \
  --profile-name c4_long_only_rr15 \
  --ticker SPY \
  --start 2025-01-01 \
  --end 2025-12-31

Tests

PYTHONPATH=src python -m pytest tests/test_public_surface.py -q
