Deevsdeevs Agent System Venue Expert

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

Navigation

Context Detection

Route to appropriate depth based on query specificity:

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
