Building an Institutional-Grade Bot: Full Architecture & Starter Code
Study the complete multi-layer architecture of an automated trading robot and grab full, ready-to-deploy Python and Node.js starter code templates.
1. The Four-Tier Bot Architecture
- Tier 1: Data Ingestion & Normalization: Ingests WebSockets and transforms tick streams into uniform OHLCV candles and clean numeric arrays.
- Tier 2: Quantitative Signal Matrix: Evaluates mathematical indicators, machine learning weights, or support/resistance bounces.
- Tier 3: Risk & Position Sizing Gatekeeper (Airbag): Calculates dynamic lot sizes, enforces daily max drawdown limits, and blocks trades if spread is too high.
- Tier 4: Execution & Lifecycle Monitor: Transmits orders, monitors fills, tracks Trailing Stop Losses, and logs performance telemetry to a web dashboard.
