# Multi-Exchange Consolidated Order Book (COB) Data Provider
|
||||
|
||||
## Overview
|
||||
|
||||
This document describes the implementation of a comprehensive multi-exchange Consolidated Order Book (COB) data provider for the gogo2 trading system. The system aggregates real-time order book data from multiple cryptocurrency exchanges to provide enhanced market liquidity analysis and fine-grain volume bucket data.
|
||||
|
||||
## BookMap API Analysis
|
||||
|
||||
### What is BookMap?
|
||||
|
||||
BookMap is a professional trading platform that provides:
|
||||
- **Multibook**: Consolidated order book data from multiple exchanges
|
||||
- **Real-time market depth visualization**
|
||||
- **Order flow analysis tools**
|
||||
- **Market microstructure analytics**
|
||||
|
||||
### BookMap API Capabilities
|
||||
|
||||
Based on research, BookMap offers three types of APIs:
|
||||
|
||||
1. **L1 (Add-ons API)**: For creating custom indicators and trading strategies within BookMap
|
||||
2. **L0 (Connect API)**: For creating custom market data connections (requires approval)
|
||||
3. **Broadcasting API (BrAPI)**: For data sharing between BookMap add-ons
|
||||
|
||||
### BookMap Multibook Features
|
||||
|
||||
BookMap's Multibook provides:
|
||||
- **Pre-configured synthetic instruments** combining data from major exchanges:
|
||||
- **USD Spot**: BTC, ETH, ADA, etc. from Bitstamp, Bitfinex, Coinbase Pro, Kraken
|
||||
- **USDT Spot**: BTC, ETH, DOGE, etc. from Binance, Huobi, Poloniex
|
||||
- **USDT Perpetual Futures**: From Binance Futures, Bitget, Bybit, OKEx
|
||||
- **Consolidated order book visualization**
|
||||
- **Cross-exchange arbitrage detection**
|
||||
- **Volume-weighted pricing**
|
||||
|
||||
### Limitations for External Use
|
||||
|
||||
**Important Finding**: BookMap's APIs are primarily designed for:
|
||||
- Creating add-ons **within** the BookMap platform
|
||||
- Extending BookMap's functionality
|
||||
- **NOT for external data consumption**
|
||||
|
||||
The APIs do not provide a simple way to consume Multibook data externally for use in other trading systems.
|
||||
|
||||
### Cost and Accessibility
|
||||
|
||||
- BookMap Multibook requires **Global Plus subscription**
|
||||
- External API access requires approval and specific use cases
|
||||
- Focus is on professional institutional users
|
||||
|
||||
## Our Implementation Approach
|
||||
|
||||
Given the limitations of accessing BookMap's data externally, we've implemented our own multi-exchange COB provider that replicates and extends BookMap's functionality.
|
||||
|
||||
## Architecture
|
