SPX 0DTE Iron Condor Trading Bot Product Requirements Document (PRD)

Goals and Background Context

Goals

Create multi-strategy trading bot platform with unified dashboard (not TWS replication)
Phase 1: Automate daily 0DTE Iron Condor trading on SPX with 9:32 ET execution
Phase 2: Add weekly 45 DTE SPY Strangle with rolling capability
Implement robust exit management with configurable profit targets and time-based closes
Enforce comprehensive risk controls including 300% stop-loss and kill-switch capability
Enable parallel strategy testing through Experiment Mode without capital risk
Provide strategy-centric monitoring with status tracking, P/L calculation, and dual time tracking (contract expiry vs strategy exit)
Track performance metrics per strategy with detailed logs and future parameter tuning
Ensure system resilience with automatic state recovery and collision prevention
Enable "set-and-forget" operation suitable for vacation periods
Create extensible architecture for additional strategies (Flyogonal, etc.)

Background Context

The idea for this project was to automate a proven options trading strategy that has demonstrated an 83.7% win rate over 300+ backtested trades: the "Daily 0DTE SPX Iron Condor". The current manual process requires daily attention at specific times, making it incompatible with travel or other commitments. By automating the strategy through Interactive Brokers' TWS API (via TWS or IB Gateway), we eliminate human error, ensure consistent execution, and free the trader from daily operational tasks while maintaining the strategy's edge. The system is designed with safety-first principles, ensuring that automation enhances rather than endangers the proven strategy's performance. Critical constraints include single trade per day limits, US market hours operation only, strict adherence to the proven strategy without autonomous optimization, and not overriding but intelligently accepting manual changes made in TWS by the user while a strategy order is currently running.

Strategy Validation & Correlation Considerations: Both SPX Iron Condor (Phase 1) and SPY Strangle (Phase 2) strategies have been extensively backtested over 3+ year periods, demonstrating consistent performance across various market conditions. While SPX and SPY correlation during stress events is acknowledged, the proven historical performance and individual strategy risk controls (300% stop-losses, time-based exits) provide adequate risk management for the current implementation. Portfolio-level correlation analysis and VIX-based regime detection are designated for future enhancement phases but are not required for initial deployment given the robust individual strategy performance and comprehensive risk controls already in place.

Requirements

Functional Requirements

FR1: Execute Iron Condor trades daily at 9:32 ET (2 minutes after market open) on SPX 0DTE options
FR2: Select short strikes targeting Delta 15 (±1.9 tolerance, preferring higher delta when equidistant)
FR3: Place long strikes exactly 20 points away from selected short strikes
FR4: Submit Iron Condor as single combo/BAG order to ensure atomic execution
FR5: Create three-order OCA group for exits: 25% profit target (LMT), 11:30 ET close (MKT), 300% stop-loss (STP). CRITICAL: Discord CRITICAL alert on FIRST exit order failure (not after retries). On technical failure: automatic retry with configurable attempts (default: 30 attempts over 10 minutes). If all retries fail: Position enters UNPROTECTED state (no exit orders active), emergency market close required. Discord alerts sent immediately on first error and continuously during retry period with current P/L and emergency close option
FR6: Support two trading modes: "Live" (real orders to TWS) and "Experiment" (hypothetical tracking only)
FR7: Maintain persistent state to recover from crashes and prevent duplicate trades
FR8: Send notifications via Discord for trade execution, errors, and critical events
FR9: Provide web dashboard showing real-time status, P/L, and trade history
FR10: Track and store all trade data including entry/exit prices, times, and reasons. Include user-editable notes field per trade for personal insights and commentary. Archive instances: Closed instances can be manually archived OR automatically after configurable days (default: 30 days). Active/running trades cannot be archived. After emergency market close, instances move to closed state and follow standard archiving rules
FR11: Implement kill-switch accessible via Discord and web interface with confirmation dialog
FR12: Respect US market calendar, skipping weekends and market holidays
FR13: Order execution with retry mechanism: Submit order as LMT at current mid-price, cancel and retry with updated mid-price at configurable intervals (default: every 5 seconds) until configurable timeout (default: 1 minute total). After timeout or max retries, mark instance as failed - enable manual archiving. Skip function: Available for scheduled instances with mandatory safety confirmation. Stop function: Available during active operations with confirmation. Stopped/skipped instances archive with SKIPPED status and null P/L, failed instances with ERROR status and null P/L
FR14: Position Sizing with Risk Management:
- Fixed Contract Mode: User sets number of contracts (default: 1)
- Dynamic Position Sizing Mode:
  - Base calculation: Min(% Net Liq per Trade, Available within Buying Power limit)
    - % Net Liq per Trade (default: 3%)
    - % Overall Buying Power Usage limit (default: 50%)
  - VIX-based adjustments (VIX value max 5 seconds old):
    - VIX > threshold X (default: 30): Reduce position by 50% (minimum 1 contract)
    - VIX > threshold Y (default: 50): Skip trade entirely
  - Pre-trade validation in Column 1 (NEXT): Display warnings for:
    - Insufficient Net Liquidity for requested position size
    - Insufficient Buying Power/Margin
    - VIX threshold conditions
  - Execution validation in Column 2 (SEARCH OPTIONS): Block trade with error for:
    - Cannot meet minimum position size (1 contract) due to capital constraints
    - VIX > threshold Y
    - Margin requirements cannot be met
FR15: Export trade history in CSV format for external analysis
FR16: Execute SPY Strangle trades weekly at configurable time (default Monday 11:45 ET / 18:45 CET, 2.25 hours after market open) using 45 DTE options. Skip entry if not a trading day. Skip entry if mandatory 21 DTE close date (Thursday, 24 calendar days forward) falls on non-trading day or after December 31st to prevent year-end tax complications. Record skip reason for audit trail (Phase 2)
FR17: Select SPY Strangle strikes targeting Delta 16 (±1.9 tolerance, preferring higher absolute delta when equidistant - same selection logic as SPX Iron Condor). Initial delta configurable in settings (default: 16). Submit Strangle as single combo/BAG order to ensure atomic execution (Phase 2)
FR18: [FUTURE ENHANCEMENT - Not in MVP] Implement defensive rolling: when strike tested (ATM/ITM) at ≤28 DTE, roll untested side to target Delta 30 (±1.9 tolerance, preferring higher absolute delta when equidistant). Maximum one roll per position (First-Touch-Rule). Continuous monitoring during market hours. Send standard notification when any leg becomes ATM/ITM at ≤28 DTE. Send escalated/prominent notification for any subsequent touches after First-Touch-Rule has been applied
FR19: Enforce mandatory close at 21 DTE for SPY Strangle regardless of P/L or roll status, executed on Thursday at 11:30 ET / 18:30 CET (2 hours after market open) on normal trading days, adjusted for half trading days (Phase 2)
FR20: Track dual time remaining: options expiry time (DTE) AND strategy exit time (TTC - Time to Close) for all positions. Store time values as days with decimal precision
FR21: Provide streamlined installation and setup process via Homebrew with private tap distribution, web-based configuration wizard, and automatic browser launch for initial setup
FR22: Instance ID format: [STRATEGY_ABBREV]-[YYMMDD]-[###] where STRATEGY_ABBREV is max 6 characters (e.g., SPXIC-240115-001). Each strategy must define its unique abbreviation
FR23: Unified retry configuration: Entry LMT orders: Use executionWindow (default: 60 seconds) with mid-price updates, 12 attempts distributed across window. All errors and failures: Standard error retry with 30 attempts at 5-second intervals (2.5 minutes total). Emergency close uses same error retry configuration. ExecutionWindow only applies to entry orders; exit orders and market orders use error retry on failure
FR24: TWS state reconciliation: Poll TWS every 10 seconds during retry operations to detect manual interventions (position closed, OCA manually set). Adapt system state accordingly and notify via Discord
FR25: Orphaned order detection: After position closure, scan TWS for any open orders matching the closed trade's strike prices and expiration dates. This includes both OCA group orders and standalone orders that may have been manually created. Alert via Discord CRITICAL when orphaned orders are detected, requiring manual cleanup in TWS before archiving
FR26: VIX Data Integration: Real-time VIX value retrieval via TWS API for position sizing decisions
- Request VIX index value (symbol: VIX) with max 5-second cache
- Architecture decision by Architect: Direct API call vs cached approach
- Required for Dynamic Position Sizing Mode
- Fallback: If VIX unavailable, use Fixed Contract Mode with warning
FR27: Real-time Statistics Updates: Performance metrics MUST update immediately when trades close
- Individual strategy metrics update within 100ms of state transition to CLOSED
- Portfolio-level metrics recalculate automatically after any strategy metric changes
- Updates trigger via state change events, not polling
- All connected clients receive metric updates via Server-Sent Events
- Database writes for metrics are asynchronous to maintain <100ms UI update performance

Non-Functional Requirements

NFR1: System must maintain connection to IB Gateway with automatic reconnection on disconnect
NFR2: All sensitive credentials must be encrypted and stored in environment variables
NFR3: System must run continuously in containerized environment (Podman) on Mac Mini server
NFR4: Response time for dashboard updates must be under 2 seconds
NFR5: System must log all actions with timestamps for audit trail
NFR6: Database must handle minimum 5 years of trade history without performance degradation
NFR7: System must send critical alerts within 10 seconds of event occurrence
NFR8: Architecture must support addition of new strategies without modifying core engine
NFR9: System must handle IB Gateway daily restart gracefully at any configured time
NFR10: Web interface must be mobile-responsive for iPhone access
NFR11: Store and process times in user-configurable timezone (default CET) and market time (ET). System must maintain both user timezone and market timezone for all time-based operations.

Meta-Strategy Model

The Meta-Strategy Model is the core abstraction that separates trading logic from UI representation, enabling infinite strategy variations through configuration alone.

Core Components

Note: Position sizing (fixed vs dynamic) is handled at the system level, not per-strategy configuration.

Key Principles

Complete Separation: Trading logic (Meta-Strategy) never knows about UI representation
Configuration-Driven: New strategies added via YAML, not code
State Independence: Each instance maintains its own state through Trading State Model
UI Abstraction: All strategies render identically in the UI (9-line card structure)

Trading State Model

Universal state machine for all strategy instances:

SCHEDULED → SEARCHING → ORDERING → PROTECTING → ACTIVE → CLOSED → ARCHIVED

State Definitions

SCHEDULED: Waiting for execution time
SEARCHING: Finding option contracts
ORDERING: Placing and filling orders
PROTECTING: Setting up exit orders (OCA group)
ACTIVE: Position live, monitoring P/L
CLOSED: Position closed, P/L finalized
ARCHIVED: Historical record

Sub-States

Each primary state can have sub-states:

READY, WAIT, WARNING (for SCHEDULED)
DOING, ERROR (for action states)
RUNNING, WARNING, ROLLING, ERROR (for ACTIVE)
DONE, ERROR, SKIPPED (for terminal states)

Dashboard Architecture

Revolutionary Kanban-Based Approach

The dashboard uses a Kanban board metaphor that maps directly to the Trading State Model:

┌─────────┬─────────┬─────────┬─────────┬─────────┬─────────┬─────────┐
│  NEXT   │ SEARCH  │ PLACE   │ SETUP   │ ACTIVE  │ CLOSED  │ ARCHIVE │
│         │ OPTIONS │ ORDER   │ EXIT    │         │         │         │
├─────────┼─────────┼─────────┼─────────┼─────────┼─────────┼─────────┤
│  Cards  │  Cards  │  Cards  │  Cards  │  Cards  │  Cards  │  Cards  │
└─────────┴─────────┴─────────┴─────────┴─────────┴─────────┴─────────┘

Column Mapping

NEXT → SCHEDULED state
SEARCH OPTIONS → SEARCHING state
PLACE ORDER → ORDERING state
SETUP EXIT → PROTECTING state
ACTIVE → ACTIVE state
CLOSED → CLOSED state
ARCHIVE → ARCHIVED state

Universal 9-Line Card Structure

EVERY card in EVERY column follows this exact structure:

Line 1: [Mode Badge] [Instance ID] [Status Badge]
Line 2: ─────────────────
Line 3: [Content based on column/state]
Line 4: [Content based on column/state]
Line 5: [Empty or content]
Line 6: [Empty or content]
Line 7: [Empty or content]
Line 8: ─────────────────
Line 9: [Primary Action Button if applicable]

This rigid structure ensures:

Consistent visual hierarchy
Predictable information placement
Clean abstraction from strategy specifics
Mobile-responsive design

Technical Architecture Overview

System Components

Core Engine: Python-based monolith in Podman container
TWS Integration: ib_async for reliable IB Gateway connection
Web Framework: FastAPI for REST API and WebSocket support
Frontend: HTMX + Server-Sent Events for real-time updates
Database: SQLite for persistence with encrypted secrets
Notifications: Discord.py for alerts and remote control
Deployment: Mac Mini server with Podman orchestration

Key Design Decisions

Modular Monolith: Single deployable unit with clear service boundaries
Strategy Registry: Dynamic loading of strategy configurations
State Machine: Centralized state management with event-driven transitions
Retry Patterns: Unified retry logic for orders and errors
Market Hours: Dynamic fetching and caching from IB API
OCA Management: Atomic creation of exit order groups
Position Reconciliation: Startup sync between database and TWS
Emergency Controls: Kill-switch and manual intervention handling

Technology Stack

Backend: Python 3.11+, ib_async v2.0.1, FastAPI
Frontend: HTMX, Tailwind CSS, DaisyUI (Aqua theme)
Database: SQLite with SQLAlchemy ORM
Messaging: Discord.py for notifications
Container: Podman for deployment
Monitoring: Built-in health checks and status endpoints
Configuration (Hybrid Approach):
- YAML files for non-sensitive trading parameters (deltas, timing, position sizing)
- Encrypted SQLite table for secrets (Discord token, IB credentials, API keys)
- Master encryption key stored in macOS Keychain
- Python cryptography library (Fernet) for symmetric encryption

Order Execution Framework Note for Architect

All strategies use unified order execution pattern: mid-price calculation from IB quotes, LMT order submission, and configurable retry logic with updated pricing on each attempt. Implement generic order execution engine with per-strategy configuration parameters: retry intervals (default: 5 seconds), timeout duration (default: 1 minute), and max attempts (default: 12). Strategy-specific execution windows (SPX IC: critical 9:32-9:33 ET timing, SPY Strangle: relaxed Friday evening timing) handled through different timeout configurations. All strategies use combo/BAG orders for atomic execution with ib_async bracketOrder() helper function and oneCancelsAll() method for OCA group management. OCA Implementation Details: Use ib.bracketOrder('BUY', quantity, limitPrice, takeProfitPrice, stopLossPrice) to create three-order structure, then place each order individually. For manual control, use oneCancelsAll([profit_order, stop_order, time_order], ocaGroup="strategy_id", ocaType=1) for custom OCA groups. This unified approach reduces code duplication while maintaining strategy-specific flexibility.

Operational Edge Case Handling Requirements for Architect

The system must handle critical operational failures gracefully to prevent capital loss and ensure reliable automated trading. Key requirements:

System Recovery & State Management:

Implement position reconciliation on startup by comparing database state with TWS actual positions
Handle bot crash scenarios during critical windows (e.g., 9:31-9:35 ET for SPX strategy) with missed window detection and trader alerts
Ensure database transaction consistency during order execution - treat entry order + exit orders as atomic unit
Implement graceful degradation during network outages with position status caching and recovery procedures

Market Disruption Handling:

Handle trading halts on underlying securities by queuing exit orders until market reopens
Manage circuit breaker scenarios with extended exit windows when markets are paused
Account for early assignment risks on American-style options (SPY) with position status monitoring
Adapt execution times for half-trading days while maintaining strategy integrity

Connection & TWS Integration:

Implement robust TWS connection management with automatic reconnection and session restoration
Handle TWS daily restart gracefully during market hours without losing active orders or positions
Implement API rate limiting and backoff strategies to prevent connection throttling
Ensure order status verification after connection restore to prevent duplicate or missed orders

Error Classification & Response:

Define clear error severity levels: INFO (recoverable), WARNING (requires attention), CRITICAL (immediate action required), FATAL (system halt required)
Implement escalating notification system with configurable channels (Discord, email, SMS)
Ensure all fatal errors trigger immediate trader notification with system status and recommended actions
Log all operational errors with sufficient context for post-incident analysis and system improvement

Fail-Safe Mechanisms:

Default to safe mode on ambiguous system state - prefer no action over potentially harmful action
Implement emergency position closure mechanisms when system integrity is compromised
Ensure kill-switch functionality remains accessible even during system degradation
Maintain audit trail of all system decisions and error responses for regulatory and debugging purposes

Market Hours Integration

The system will dynamically fetch and cache market hours from IB API to handle RTH-relative timing, DST transitions, and market holidays.

Future Enhancement Roadmap

Defensive Rolling for SPY Strangle (Post-Epic 8)

Priority: High - Important risk management feature Complexity: High - Requires careful implementation and testing

Implementation Requirements:

Continuous monitoring of strike positions vs underlying
Automatic roll execution when strike becomes ATM/ITM at ≤28 DTE
Roll only the untested side to Delta 30
First-Touch-Rule: Maximum one roll per position
Clear notifications and audit trail
Experiment mode testing before live deployment

Why Deferred:

Adds significant complexity to initial SPY Strangle implementation
Requires extensive testing to ensure correct execution
Better to establish stable base strategy first
Can be added incrementally once base strategy proven

Discord Command Extensions (Post-Epic 5)

After the minimal Discord integration is proven stable, consider adding:

Status & Information Commands:

!status - Current position status and P/L
!today - Today's scheduled and executed trades
!history [days] - Recent trade history
!metrics - Performance metrics summary

Control Commands:

!skip [date] - Skip specific trading day
!pause - Pause automation temporarily
!resume - Resume automation
!settings - View current settings

Advanced Features:
