Test Multi-Exchange Consolidated Order Book (COB) Provider
|
||||
|
||||
This script demonstrates the functionality of the new multi-exchange COB data provider:
|
||||
1. Real-time order book aggregation from multiple exchanges
|
||||
2. Fine-grain price bucket generation
|
||||
3. CNN/DQN feature generation
|
||||
4. Dashboard integration
|
||||
5. Market analysis and signal generation
|
||||
|
||||
Run this to test the COB provider with live data streams.
