# Infrastructure Overview

#### 1. **Token Management & Data Layer**

* Users can track and manage tokens by providing contract addresses directly.
* The system collects price data, transaction history, and liquidity details.
* Historical data is stored for trend tracking and strategy backtesting.

#### 2. **Strategy & Risk Layer**

* User-defined strategies specify entry/exit rules, stop-loss, and profit targets.
* Risk thresholds (price drops, position size limits, slippage tolerances) are applied before any trade is executed.
* This layer acts as a filter, ensuring only valid trades move forward.

#### 3. **Core Engine**

* Handles real-time market monitoring.
* Executes trades based on configured strategies.
* Optimized for high throughput, with faster execution and improved RPC handling for reliability.

#### 4. **Execution Handlers**

* Specialized services that construct, send, and confirm buy/sell transactions on the Solana blockchain.
* After each trade, token states are updated (holdings, PnL, active orders).

#### 5. **Persistence Layer (Database)**

* MongoDB stores all relevant data: token states, trading history, risk events, and execution logs.
* Ensures persistence across sessions and enables accurate reporting/analysis.

#### 6. **User Dashboard & Communication Layer**

* The dashboard, connected via **Socket.IO**, streams real-time data to users.
* Displays balances, active orders, historical trades, and live execution updates.
* Provides configuration panels for strategies, risk parameters, and wallet details.
