Bases: Thread

A Python SDK by LUCIT to access and manage multiple local Binance DepthCaches with Python in a simple, fast, flexible, robust and fully-featured way.

Binance API documentation:
Parameters:

  • exchange (str) – Select binance.com, binance.com-testnet, binance.com-futures, binance.com-futures-testnet (default: binance.com)

  • default_refresh_interval (int) – The default refresh interval in seconds, default is None. The DepthCache is reset and reinitialized at this interval.

  • init_interval (float (seconds)) – Only one request to the Binance REST API is permitted to all DepthCaches.

  • init_time_window (int (seconds)) – Only one request to the Binance REST API is permitted per DepthCache in this time window (specified in seconds).

  • high_performance (bool) – If True, access to the depth snapshots via REST in the INIT process is not regulated. Be careful!

  • auto_data_cleanup_stopped_streams (bool) – The parameter “auto_data_cleanup_stopped_streams=True” can be used to inform the UBWA instance that all remaining data of a stopped stream should be automatically and completely deleted.

  • depth_cache_update_interval (int) – Update speed of the depth stream in milliseconds. More info: https://github.com/LUCIT-Systems-and-Development/unicorn-binance-local-depth-cache/wiki/update_intervals

  • 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. 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()

  • 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

  • ubra_manager (BinanceRestApiManager) – Provide a shared unicorn_binance_rest_api.manager instance

  • 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
