InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
One more option is my own fully open-source library, but it has only partial implementation for some brokers. Some of them provide market data, some - execution. Nevertheless, you can implement IGatewayModel interface for multiple brokers and use them together using unified API.
