What it does
This is the operating guide for the lo2cin4bt quantitative research and backtesting repository. It covers launching the project, writing or reviewing strategy run and walk-forward analysis configs, running local backtests, Parameter Matrix and rolling validation runs, and reading the frontend metrics and AI-readable result packs. It also helps beginners who get stuck during first-run setup or at runtime.
Answers are meant to stay tied to what the repository actually contains. The agent treats the strategy run, generated snapshots, app payloads and tests as the source of truth, does not invent config fields, metrics or interface features, and labels outside finance context as external. A set of reference files covers config fields, a metric dictionary, indicator recipes, troubleshooting and the runtime architecture, and replies come in Traditional Chinese when you write in Chinese.
The skill is for research and teaching only. It will not deploy anything, place trades, enable live trading, move funds or change external accounts, and broker or exchange accounts may be used only for read-only market data. Nothing it says counts as investment advice.
When your agent uses it
- Installing and launching lo2cin4bt for the first time
- Writing or reviewing a strategy run config or a walk-forward analysis config
- Making sense of backtest metrics, artifacts and frontend pages
- Recovering from setup or runtime errors as a beginner
Example prompts
- “Help me install lo2cin4bt and run my first backtest.”
- “Review this strategy config and tell me which fields are wrong.”
- “Explain what the Sharpe ratio on the results page tells me.”
- “Set up a walk-forward analysis for my moving-average strategy.”
Requirements
- A local checkout of the lo2cin4bt repository
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Read the canonical runtime architecture and classify the task.
- Load the exact task skill and inspect current repo evidence.
- Perform the smallest structural change or operation that satisfies the request.
- Run skill-owned validation and record evidence.
- Close with a semantic summary and durable report when required.
What it can do on your machine
Read from SKILL.md and the folder at commit d2e0863. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
uv
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
lo2cin4bt Backtesting Assistant loads about 2.6k tokens when it runs, and up to ~30k if it reads all its reference files. Until then it costs about 106 tokens; SKILL.md has 1,112 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,112 words (~2,618 tokens).
“Provide the canonical project operating rules for local strategy authoring, Rust-backed simulation, explicit validation workflows, artifact interpretation, teaching, and troubleshooting.”
