3. Functional Requirements as Story Points

• As a Trader, I should be able to perform market analysis with low latency by connecting to my broker to make informed trading decisions. explicit
• As a Trader, I should be able to execute trades with low latency by connecting to my broker to ensure timely transactions. explicit
• As a Trader, I should be able to sign up for an account to access the trading dashboard. required_inference
• As a Trader, I should be able to log in to my account to access the trading dashboard. required_inference
• As a Trader, I should be able to manage my session to maintain persistent identity while using the system. required_inference

4. User Personas

• Traders: The primary users who will perform analysis and execute trades using the system. They require a dedicated interface to connect with brokers and perform real-time trading activities.

5. Core User Flows

• Trader Flow:
  1. Access the Landing page to understand the system's capabilities.
  2. Navigate to the Authentication page to sign up or log in.
  3. Upon successful authentication, access the Trading Dashboard.
  4. Perform market analysis using real-time data and trading indicators.
  5. Execute trades by confirming trade parameters and connecting to the broker.
  6. Receive trade execution confirmation and review trade records.

6. Visuals Colors and Theme

• Primary: #1E90FF (Dodger Blue)
• Primary Light: #63B8FF (Light Dodger Blue)
• Secondary: #FFD700 (Gold)
• Accent: #FF4500 (Orange Red)
• Highlight: #32CD32 (Lime Green)
• Background: #F0F8FF (Alice Blue)
• Surface: #FFFFFF (White)
• Text: #000000 (Black)
• Text Muted: #696969 (Dim Gray)
• Border: #D3D3D3 (Light Gray)

7. Signature Design Concept

The Trading Dashboard will feature a clean and intuitive interface with a focus on real-time data visualization. The design will incorporate a grid layout to display market data and trading indicators prominently. The use of contrasting colors will highlight actionable items such as trade execution buttons. Typography will be clear and legible, ensuring traders can quickly interpret information. The dashboard will provide immediate feedback on actions, with loading indicators and error messages where necessary.

8. Interaction Model & Motion Direction

• Trading Dashboard: Animated

  • Moderate scroll-triggered reveals and hover transitions will enhance user interaction.
  • Interactive elements will employ spring physics for a polished experience.

• Landing: Static

  • The page will provide a clear and concise overview without motion distractions.

• Authentication: Static

  • Focus on clarity and ease of use for form interactions.

9. Non-Functional Requirements

• Real-time Low Latency: The system must support extremely low latency to ensure timely trade execution and analysis. explicit
• Persistent Identity: The system must maintain persistent identity for traders to ensure secure and continuous access to trading functionalities. required_inference

10. Tech Stack

• Frontend: React for Web
• Backend: Python, FastAPI
• Database: MySQL or MariaDB, use Alembic for migrations
• Local Orchestration: Docker, docker-compose
• Server-side Orchestration: Kubernetes

11. Assumptions and Constraints

• The system will focus on real-time low latency trading functionalities and will not include generic trading platform features unless explicitly required.
• Persistent identity is necessary for traders to access and utilize the trading dashboard.

12. Glossary

• Trader: An individual who performs market analysis and executes trades using the system.
• Real-time Trading: The ability to perform trading activities with minimal delay.
• Low Latency: The minimal time delay between a trader's action and the system's response.
• Persistent Identity: The continuous recognition of a user's identity across sessions.
