When to use
Use this skill when you are:
- Backtesting an existing strategy from
wayfinder_paths/strategies/
- Validating a new trading strategy idea before production deployment
- Analyzing historical performance (Sharpe, drawdown, CAGR, funding PnL)
- Testing any strategy type: momentum, delta-neutral, yield rotation, carry trade
- Testing different leverage levels or parameter combinations
How to use
First, determine if you're backtesting an existing strategy or a new idea:
Backtesting an existing strategy (from wayfinder_paths/strategies/)
Load these rules:
- rules/backtesting.md — Always load first. Config reference, stats format, gotchas.
- rules/existing-strategies.md — REQUIRED for existing strategies. Workflow for reading strategy source code, extracting parameters, fetching real Delta Lab data, and faithfully reproducing signal logic. Never use generic helpers with default parameters for existing strategies.
- Load the strategy-type-specific rule if applicable (yield-strategies.md).
Backtesting a new strategy idea
Load these rules in order (most to least specific for your strategy type):
rules/backtesting.md — Strategy type → helper mapping, quick start examples, config reference, stats format, gotchas, production path. Always load this first.
rules/yield-strategies.md — Detailed patterns for lending/yield strategies: supply rate rotation, leveraged yield loops, carry trade, multi-venue benchmark. Load when the user's strategy involves lending protocols, supply APRs, or borrow rates.
Examples
- examples/basic_momentum.py — Cross-sectional momentum using
quick_backtest
- examples/delta_neutral.py — Delta-neutral basis carry using
backtest_delta_neutral
- examples/yield_rotation.py — USDC rotation across lending venues using
backtest_yield_rotation
- examples/carry_trade.py — Borrow cheap / supply expensive using
backtest_carry_trade
