You are correct. When I referred to 'real-time', I meant it in the sense that it is as efficient as consuming data directly from the exchange's WebSocket because, during the consumption stage, data is directly consumed from the exchange, not an intermediate server.

Since Binance only provides 100ms diffs, there isn’t 'real-time' in the sense of receiving each atomic orderbook change. Thank you for your feedback, I changed the description.

Whew! 100ms??
