Thread
A local Binance DepthCache Manager for Python that supports multiple depth caches in one instance in an easy, fast, flexible, robust and fully-featured way.
Binance API documentation: https://developers.binance.com/docs/binance-api/spot-detail/web-socket-streams#diff-depth-stream https://binance-docs.github.io/apidocs/futures/en/#diff-book-depth-streams
- Parameters:
exchange (str) – Select binance.com, binance.com-testnet, binance.com-margin, binance.com-margin-testnet, binance.com-isolated_margin, binance.com-isolated_margin-testnet, binance.com-futures, binance.com-futures-testnet, binance.com-coin_futures, binance.us, trbinance.com, jex.com, binance.org or binance.org-testnet (default: binance.com)
default_refresh_interval (int) – The default refresh interval in seconds, default is None.
default_update_interval (int) – Update speed of the depth webstream in milliseconds. More info: https://github.com/LUCIT-Systems-and-Development/unicorn-binance-local-depth-cache/wiki/update_intervals This can be overwritten with update_interval of create_depth_cache().
default_websocket_close_timeout (int) – The close_timeout parameter defines a maximum wait time in seconds for completing the closing handshake and terminating the TCP connection. This parameter is passed through to the websockets.client.connect()
default_websocket_ping_interval (int) –
Once the connection is open, a Ping frame is sent every ping_interval seconds. This serves as a keepalive. It helps keeping the connection open, especially in the presence of proxies with short timeouts on inactive connections. Set ping_interval to None to disable this behavior. This parameter is passed through to the websockets.client.connect()
default_websocket_ping_timeout (int) –
If the corresponding Pong frame isn’t received within ping_timeout seconds, the connection is considered unusable and is closed with code 1011. This ensures that the remote endpoint remains responsive. Set ping_timeout to None to disable this behavior. This parameter is passed through to the websockets.client.connect()
disable_colorama (bool) – set to True to disable the use of colorama
warn_on_update (bool) – set to False to disable the update warning
lucit_api_secret (str) – The api_secret of your UNICORN Binance Suite license from https://shop.lucit.services/software/unicorn-binance-suite
lucit_license_ini (str) – Specify the path including filename to the config file (ex: ~/license_a.ini). If not provided lucitlicmgr tries to load a lucit_license.ini from /home/oliver/.lucit/.
lucit_license_profile (str) – The license profile to use. Default is ‘LUCIT’.
lucit_license_token (str) – The license_token of your UNICORN Binance Suite license from https://shop.lucit.services/software/unicorn-binance-suite
ubra_manager (BinanceRestApiManager) – Provide a shared unicorn_binance_rest_api.manager instance
ubwa_manager (BinanceWebSocketApiManager) – Provide a shared unicorn_binance_websocket_api.manager instance. Use enable_stream_signal_buffer=True otherwise the depth_cache will not work as it should!

refresh_interval (int) – The refresh interval in seconds, default is the default_refresh_interval of BinanceLocalDepthCache.
websocket_close_timeout (int) –
The close_timeout parameter defines a maximum wait time in seconds for completing the closing handshake and terminating the TCP connection. This parameter is passed through to the websockets.client.connect()
websocket_ping_interval (int) –
Once the connection is open, a Ping frame is sent every ping_interval seconds. This serves as a keepalive.
