# Crypto Derivatives Skill (Binance Futures Positioning) ## When to use Trigger on any crypto recommendation where you need to know: - **Is the market crowded long or short?** (funding rate, L/S ratio) - **Is open interest rising or falling?** (fresh positioning vs unwind) - **Are top traders disagreeing with retail?** (the classic divergence setup) - **Is there flush risk?** (very crowded long with positive funding = liquidation cascade fuel) - **Pre-trade event-risk check** for derivatives-driven moves before considering spot entry. Do NOT trigger this skill on US equities, KLSE, or any non-crypto asset. ## Why this exists Funding rates, open interest, and long/short ratios are first-class signals for crypto. CoinGecko (the `crypto-coingecko` skill) gives sentiment votes and dev activity but NOT derivatives positioning. Massive's crypto coverage is spot-focused. Without this skill, the "flow" leg of AGENTS.md §4 confluence is missing for crypto. ## Source **Binance Futures public REST API** (`fapi.binance.com`). No authentication required, no key needed, no rate-limit issues at retail-research scale. Binance is the largest futures venue by far — its book IS the market for BTC/ETH/SOL positioning. For altcoins with thinner Binance liquidity, the read is less reliable and you may need to cross-check with Bybit/OKX. ## Subcommands ### `snapshot` — current positioning + recent trend ``` python3 .claude/skills/crypto-derivatives/binance_derivs.py snapshot --symbol BTC
