Package: valr-python
A Python SDK for VALR cryptocurrency exchange APIs.Installationpip install valr-pythonYou can also install the in-development version with:pip install https://github.com/jonathanelscpt/valr-python/archive/master.zipAuthenticationAuthenticating to VALR API private resources requires a valid API Key from theVALR exchange.Synchronous REST API ClientTo use thesynchronousREST API client:>>>fromvalr_pythonimportClient>>>fromvalr_python.exceptionsimportIncompleteOrderWarning>>>fromdecimalimportDecimal>>>>>>c=Client(api_key='api_key',api_secret='api_secret')>>>c.rate_limiting_support=True# honour HTTP 429 "Retry-After" header values>>>limit_order={..."side":"SELL",..."quantity":Decimal('0.1'),..."price":Decimal('10000'),..."pair":"BTCZAR",..."post_only":True,...}>>>try:...res=c.post_limit_order(**limit_order)...order_id=res['id']...print(order_id)...exceptIncompleteOrderWarningasw:# HTTP 202 Accepted handling for incomplete orders...order_id=w.data['id']...print(order_id)...exceptExceptionase:...print(e)"558f5e0a-ffd1-46dd-8fae-763d93fa2f25"Asynchronous REST API ClientTheasynchronousREST API client is still in development.Coming soon!WebSocket API ClientTo use the WebSocket API client:>>>importasyncio>>>fromtypingimportDict>>>frompprintimportpprint>>>fromvalr_pythonimportWebSocketClient>>>fromvalr_python.enumimportTradeEvent>>>fromvalr_python.enumimportWebSocketType>>>>>>defpretty_hook(data:Dict):...pprint(data)>>>>>>c=WebSocketClient(api_key='api_key',api_secret='api_secret',currency_pairs=['BTCZAR'],...ws_type=WebSocketType.TRADE.name,...trade_subscriptions=[TradeEvent.MARKET_SUMMARY_UPDATE.name],...hooks={TradeEvent.MARKET_SUMMARY_UPDATE.name:pretty_hook})>>>loop=asyncio.get_event_loop()>>>loop.run_until_complete(c.run()){'currencyPairSymbol':'BTCZAR','data':{'askPrice':'151601','baseVolume':'314.7631144','bidPrice':'151600','changeFromPrevious':'2.14','created':'2020-02-06T22:47:03.129Z','currencyPairSymbol':'BTCZAR','highPrice':'152440','lastTradedPrice':'151600','lowPrice':'146765','previousClosePrice':'148410','quoteVolume':'47167382.04552981'},'type':'MARKET_SUMMARY_UPDATE'}This library leverageswebsocketsandasyncioand is thus a coroutine-based API client.  Both of
VALR’sAccount WebSocket connectionandTrade WebSocket connectionAPI endpoints are included.  Furthermore,
the SDK fully supports VALR’s subscription methods for bothAccountandTradeendpoints.
Please see theVALR API documentationfor further information.For each subscription, a hook must be provided to process the WS responses.  Failing to do so raises
aHookNotFoundErrorexception.  For ease of use, severalEnumclasses have been implemented
(as showcased above) for client instantiation and hook consumption of API responses. However, client input is
accepted instrformat.Although not completely minimalistic, please note that the SDK is implemented as a thin client and parsing of API
streams response is left up to the application user.DevelopmentTo execute all tests run:toxNote, to combine the coverage data from all the tox environments run:Windowsset PYTEST_ADDOPTS=--cov-append
