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.

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

            ticker="SPY",
            start=datetime(2025, 1, 1),

finally:

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.

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

Run the public walk-forward wrapper:

python -m cutebacktests.cli run-walk-forward-profile-backtest \
  --profile-name c4_long_only_rr15 \
  --ticker SPY \
  --start 2025-01-01 \
  --end 2025-12-31 \
  --output-dir tmp/walkforward_spy

Audit daily options tradability before a backtest:

python -m cutebacktests.cli sample-option-tradability \
  --ticker SPY \
  --end-day 2025-12-31 \
  --lookback-days 30 \
  --output-dir tmp/tradability_spy
