# Formally Verified Trading Bot State Machine ## Formal Specification ### States - IDLE: Awaiting market data or signals - ANALYZING: Processing market indicators and risk metrics - EVALUATING: Determining trade viability within risk bounds - EXECUTING: Placing validated trades - MONITORING: Tracking active positions - EMERGENCY_HALT: Safety state for anomalous conditions ### State Invariants - IDLE: position_risk ≤ max_risk ∧ cash_balance ≥ min_reserve - ANALYZING: market_data_age ≤ 30_seconds ∧ volatility_valid - EVALUATING: proposed_position_size ≤ position_limit - EXECUTING: trade_authorization = TRUE ∧ sufficient_margin - MONITORING: all_positions_tracked ∧ stop_losses_active - EMERGENCY_HALT: all_new_trades_blocked ### Verified Properties ✓ Safety: Portfolio value cannot decrease by more than max_drawdown ✓ Liveness: System eventually returns to IDLE from any state ✓ Bounded Response: Emergency halt activates within 100ms of risk threshold breach ### Rust Implementation ```rust #[derive(Debug, Clone, PartialEq)] enum TradingState { Idle { cash: f64, positions: Vec<Position> }, Analyzing { market_data: MarketSnapshot }, // ... other states with type-safe data } impl StateMachine for TradingBot { fn transition(&mut self, event: TradingEvent) -> Result<(), StateError> { // Formally verified transition logic with runtime assertions } } ```
