# Multi-Modal Trading System Design Document

## Overview

The Multi-Modal Trading System is designed as an advanced algorithmic trading platform that combines Convolutional Neural Networks (CNN) and Reinforcement Learning (RL) models orchestrated by a decision-making module. The system processes multi-timeframe and multi-symbol market data (primarily ETH and BTC) to generate trading actions.

This design document outlines the architecture, components, data flow, and implementation details for the system based on the requirements and existing codebase.

## Architecture

The system follows a modular architecture with clear separation of concerns:
