venue-expert

This skill should be used when the user asks about "market microstructure", "exchange mechanics", "order book", "auction", "NBBO", "Reg NMS", "trading venue", "halt", "LULD", "tick size", "maker-taker", "price-time priority", "SIP", "direct feed", "TRF", "wholesaler", "PFOF", "best execution", "trade-through", "ISO", "opening cross", "closing cross", "NOII", "ITCH", "OUCH", or mentions specific exchanges (Nasdaq, NYSE, CME, Binance, SHFE, DCE, CZCE, CFFEX, INE, etc.). For Chinese futures: "CTP", "综合交易平台", "夜盘", "night session", "看穿式监管", "position limits", "持仓限额", queue position in Chinese markets, or Chinese product codes (rb, cu, sc, if, ic, i, j, ta, ma, etc.).

SKILL.md

Venue Expert

Hierarchical microstructure knowledge base for trading venues. Primary use cases: research, debugging, and building trading systems.

Purpose

Provide deep venue-specific expertise for:

  • Quants building execution models and alpha signals
  • Developers implementing feed handlers and order entry
  • Researchers studying market microstructure
  • Debuggers diagnosing trading system issues

Hierarchy Model

Knowledge is organized in an inheritance hierarchy:

Asset Class (equity, futures, crypto, fx)
    |
    v
Geography (amer, emea, apac)
    |
    v
Exchange (nasdaq, nyse, cme, binance)

Each level inherits concepts from its parent. Exchange-level files assume familiarity with geo-level and asset-class-level concepts.

Current Coverage

Implemented paths:

  • equity/ - Equity market fundamentals
  • equity/amer/ - US equity market structure (Reg NMS, NBBO, SIP, TRF)
  • equity/amer/nasdaq/ - Nasdaq-specific mechanics (ITCH, OUCH, crosses)
  • futures/ - Futures market fundamentals
  • futures/apac/ - APAC futures overview
  • futures/apac/china/ - Chinese futures (CTP, 5 exchanges, regulatory)
  • futures/apac/china/shfe/ - SHFE metals/energy
  • futures/apac/china/dce/ - DCE ferrous/agricultural
  • futures/apac/china/czce/ - CZCE agricultural/chemicals
  • futures/apac/china/cffex/ - CFFEX financial futures
  • futures/apac/china/ine/ - INE internationalized products

Planned paths:

  • equity/amer/nyse/ - NYSE mechanics
  • equity/emea/lse/ - London Stock Exchange
  • futures/amer/cme/ - CME Group
  • crypto/binance/ - Binance exchange

Navigation

Context Detection

Route to appropriate depth based on query specificity:

Query Pattern Target File
Generic equity concepts equity/equity.md
US market structure, Reg NMS, NBBO equity/amer/equity_amer.md
Nasdaq-specific (ITCH, NOII, crosses) equity/amer/nasdaq/nasdaq.md
Generic futures concepts futures/futures.md
APAC futures overview futures/apac/futures_apac.md
Chinese futures, CTP, 夜盘 futures/apac/china/futures_china.md
SHFE-specific (metals, CloseToday) futures/apac/china/shfe/shfe.md
DCE-specific (iron ore, stop orders) futures/apac/china/dce/dce.md
CZCE-specific (3-digit years, UpdateMillisec=0) futures/apac/china/czce/czce.md
CFFEX-specific (index futures, restrictions) futures/apac/china/cffex/cffex.md
INE-specific (crude oil, foreign access) futures/apac/china/ine/ine.md

Drill-Down Behavior

Start at the most specific applicable level. Reference parent concepts without repeating them. For example, when discussing Nasdaq auctions, assume familiarity with US equity auction concepts from equity_amer.md.

Reference Organization

Each level has a references/ directory with subdirectories:

  • regulatory/ - Rules, regulations, compliance guidance
  • specs/ - Protocol specifications, data formats

Reference files provide deep detail on specific topics. Load them when queries require specification-level precision.

Debugging Checklist

When debugging trading system issues:

US Equity

  1. Feed issues - Check sequence gaps, timestamp alignment, halt state handling
  2. Auction issues - Verify order type eligibility, cutoff times, NOII parsing
  3. Execution issues - Validate tick/lot compliance, fee tier, priority rules
  4. Regulatory issues - Confirm trade-through protection, best execution logic

Chinese Futures (CTP)

  1. Data issues - DBL_MAX validation (1.7976931348623157e+308), CZCE UpdateMillisec=0, night replay filtering
  2. Session issues - TradingDay vs ActionDay semantics, 21:00 reset, trading breaks (10:15-10:30)
  3. Order issues - CloseToday/CloseYesterday (SHFE/INE), cancel-replace queue loss, DCE stop orders
  4. Auth issues - 看穿式监管 AppID/AuthCode, CTP version ≥6.3.15, physical machine required
  5. Gap issues - CTP has NO replay; reconnection gaps are permanent data loss
