Vibe-Trading is a personal trading agent that gives an AI system tools for market analysis, algorithmic trading, backtesting, and related workflows. It is for users who want an agent to research and evaluate trading strategies or manage simulated and other trading activities. The catalogue contains skills that expose these trading capabilities to compatible agents.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

- NVIDIA SkillSpector warn
SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00042 | $0.01935 |
| Opus 5 | $0.00021 | $0.00967 |
| Sonnet 5 | $0.00008 | $0.00387 |
| Haiku 4.5 | $0.00004 | $0.00194 |
Grade A, and why
options-advanced scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Advanced Options Strategies
Overview
Go beyond basic option strategies (covered call / protective put) and focus on trading opportunities along the volatility dimension. Core idea: option price = intrinsic value + time value, and advanced trading essentially trades the volatility expectations embedded behind that time value.
Applicable scenarios:
- Identifying arbitrage opportunities when the volatility surface is abnormal (
skew/term structure) - Fine-grained management of portfolio Greeks exposures (not just Delta hedging)
- Building structured strategies across maturities and strikes
- Practical application in 50ETF / 300ETF / commodity options
Core Concepts
Volatility Surface
Three-dimensional structure: strike × expiry × implied volatility.
Key dimensions:
| Dimension | Meaning | Typical Shape |
|---|---|---|
| Smile / Skew | IV across strikes for the same expiry | China A-shares: left-skewed (put IV > call IV) |
| Term Structure | IV across expiries for the same strike | Normal case: near-month IV < far-month IV |
| Surface dynamics | Parallel or nonlinear movement of the entire surface | In panic, the whole surface lifts, and near-month IV lifts faster |
SABR model parameters:
α (alpha): initial volatility level, around 0.2-0.5
β (beta): CEV exponent, equities usually use 0.5-1.0
ρ (rho): correlation between volatility and the underlying, usually -0.3 to -0.7 in China A-shares (negative = left skew)
ν (nu): volatility of volatility (vol of vol), around 0.3-0.8
Local Vol vs SABR:
- Local Vol (Dupire): backed out from market prices, exact fit but unstable extrapolation
- SABR: parameterized model, 4 parameters capture surface dynamics and extrapolate more reasonably
Dynamic Greeks Management
First-order Greeks:
| Greek | Meaning | Management Approach |
|---|---|---|
| Delta (Δ) | Sensitivity to underlying price | Hedge frequency: daily for ATM, every 2-3 days for OTM |
| Vega (ν) | Sensitivity to IV | Calendar spreads can isolate Vega exposure |
| Theta (Θ) | Time decay | Short-option strategies are naturally positive Theta, but watch Gamma risk |
| Rho (ρ) | Sensitivity to rates | Relevant for long-dated options, usually ignorable for short-dated options |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

options-advanced is a skill published in the GitHub repository HKUDS/Vibe-Trading (33,177 stars, last pushed today), licensed MIT. It adds 42 tokens to every session and 1,935 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

polymarket

backtesting
Use when running, interpreting, or designing backtests on Superior Trade — anything about backtest windows, trade-count thresholds, exit-reason mix, parameter sweeps, walk-forward validation, zero-trade diagnosis, compute-cost estimation, or "is this backtest result trustworthy?". Pair with the relevant strategy…
basis-arb
Use when the user asks for spot-perp basis trade, basis arbitrage, cash-and-carry, perp discount, or any setup that reads the spot–perp basis as a positioning signal. Long-perp leg only — pure two-leg basis arb requires a paired spot short (or long) which Freqtrade can't run cleanly. The strategy below captures the…

Use when the user asks about fees, fee optimization, slippage, maker vs taker, post-only or ALO orders, fee tiers, builder code fees, effective spread, order pricing, lowering trading costs, or why a live Hyperliquid Freqtrade strategy underperforms its backtest. Also use proactively for high-turnover designs (5m or…
