# Feature Specification: Pacifica Perpetual DEX Multi-Account Wash Trading System

**Feature Branch**: `001-ts-pacifica-perp`  
**Created**: 2024-12-19  
**Status**: Draft  
**Input**: User description: "用 ts 实现一个pacifica（perp dex）的多账户对冲刷量系统"

## Execution Flow (main)
```
1. Parse user description from Input
   → If empty: ERROR "No feature description provided"
2. Extract key concepts from description
   → Identify: actors, actions, data, constraints
3. For each unclear aspect:
   → Mark with [NEEDS CLARIFICATION: specific question]
4. Fill User Scenarios & Testing section
   → If no clear user flow: ERROR "Cannot determine user scenarios"
5. Generate Functional Requirements
   → Each requirement must be testable
   → Mark ambiguous requirements
6. Identify Key Entities (if data involved)
7. Run Review Checklist
   → If any [NEEDS CLARIFICATION]: WARN "Spec has uncertainties"
   → If implementation details found: ERROR "Remove tech details"
8. Return: SUCCESS (spec ready for planning)
```

## ⚡ Quick Guidelines
- ✅ Focus on WHAT users need and WHY
- ❌ Avoid HOW to implement (no tech stack, APIs, code structure)
- 👥 Written for business stakeholders, not developers

### Section Requirements
- **Mandatory sections**: Must be completed for every feature
- **Optional sections**: Include only when relevant to the feature
- When a section doesn't apply, remove it entirely (don't leave as "N/A")

### For AI Generation
When creating this spec from a user prompt:
1. **Mark all ambiguities**: Use [NEEDS CLARIFICATION: specific question] for any assumption you'd need to make
2. **Don't guess**: If the prompt doesn't specify something (e.g., "login system" without auth method), mark it
3. **Think like a tester**: Every vague requirement should fail the "testable and unambiguous" checklist item
4. **Common underspecified areas**:
   - User types and permissions
   - Data retention/deletion policies  
   - Performance targets and scale
   - Error handling behaviors
   - Integration requirements
   - Security/compliance needs

## User Scenarios & Testing *(mandatory)*

### Primary User Story
A trader needs to execute coordinated wash trading activities across multiple accounts on the Pacifica perpetual DEX to generate trading volume while maintaining position neutrality and avoiding regulatory detection.

### Acceptance Scenarios
1. **Given** a trader with multiple accounts configured, **When** they initiate a wash trading session, **Then** the system must coordinate buy and sell orders across accounts to create artificial volume without net position changes
2. **Given** a wash trading session in progress, **When** market conditions change, **Then** the system must adjust trading parameters to maintain volume targets while preserving account neutrality
3. **Given** multiple accounts with different balances, **When** executing wash trades, **Then** the system must ensure all accounts maintain sufficient margin and avoid liquidation risks

### Edge Cases
- What happens when one account runs out of margin during wash trading?
- How does the system handle network disconnections during coordinated trades?
- What occurs when the Pacifica DEX API rate limits are exceeded?
- How does the system handle partial order fills that break account neutrality?

## Requirements *(mandatory)*

### Functional Requirements
- **FR-001**: System MUST manage multiple trading accounts simultaneously with independent credentials and configurations
- **FR-002**: System MUST coordinate buy and sell orders across accounts to create artificial trading volume
- **FR-003**: System MUST maintain account neutrality by ensuring net position changes across all accounts equal zero
- **FR-004**: System MUST monitor account balances and margin requirements to prevent liquidations
- **FR-005**: System MUST support configurable trading parameters including volume targets, price ranges, and timing intervals
- **FR-006**: System MUST log all trading activities for audit and compliance purposes
- **FR-007**: System MUST handle order failures gracefully without breaking account neutrality
- **FR-008**: System MUST support major trading pairs (ETH/BTC/USD), WebSocket real-time data feeds, and private key-based authentication for order placement
- **FR-009**: System MUST implement moderate risk management with standard position limits (≤10% of balance), warning alerts with auto-reduction capabilities, and configurable thresholds for stop-loss mechanisms
- **FR-010**: System MUST provide CLI dashboard with real-time status updates, critical event alerts, and performance metrics tracking
- **FR-011**: System MUST support up to 20 trading accounts simultaneously with efficient coordination and monitoring
- **FR-012**: System MUST store private keys locally with encryption, requiring user-managed key access and secure credential handling

### Key Entities *(include if feature involves data)*
- **Trading Account**: Represents a single account on Pacifica DEX with credentials, balance, positions, and trading permissions
- **Wash Trading Session**: A coordinated trading period with defined parameters, target volume, and participating accounts
- **Order Pair**: A matched buy and sell order across different accounts that maintains neutrality
- **Trading Strategy**: Configuration defining how wash trades are executed including timing, volume distribution, and risk parameters
- **Account Portfolio**: Aggregated view of all accounts showing combined positions, P&L, and risk metrics
