Thanks for the suggestion.

Notes for implementation perspective:

• BasicClient will work. It supports subscribing to multiple topics from a single socket.
• Subscription format takes the form: ws.send('{"op":"subscribe","args":["trade.BTCUSD|XRPUSD"]}') where each market is concatenated
• The use of semaphore is likely not required, it supports a "subscribe all" functionality and has a limited number of markets.
• Heartbeats are recommended every 30s - ws.send('{"op":"ping"}');
• Subscription responses are provided for each subscribed topic

The following relevant APIs are supported:

• Ticker - https://bybit-exchange.github.io/docs/inverse/#t-websocketinstrumentinfo
• Trades - https://bybit-exchange.github.io/docs/inverse/#t-websockettrade
• L2Updates (with initial L2Snapshot) - https://bybit-exchange.github.io/docs/inverse/#t-websocketorderbook200
• Candles - https://bybit-exchange.github.io/docs/inverse/#t-websocketklinev2
