[docs]class Client:
"""
Replacement for ``ibapi.client.EClient`` that uses asyncio.
The client is fully asynchronous and has its own
event-driven networking code that replaces the
networking code of the standard EClient.
It also replaces the infinite loop of ``EClient.run()``
with the asyncio event loop. It can be used as a drop-in
replacement for the standard EClient as provided by IBAPI.
Compared to the standard EClient this client has the following
additional features:
* ``client.connect()`` will block until the client is ready to
serve requests; It is not necessary to wait for ``nextValidId``
to start requests as the client has already done that.
The reqId is directly available with :py:meth:`.getReqId()`.
* ``client.connectAsync()`` is a coroutine for connecting asynchronously.
* When blocking, ``client.connect()`` can be made to time out with
the timeout parameter (default 2 seconds).
* Optional ``wrapper.priceSizeTick(reqId, tickType, price, size)`` that
combines price and size instead of the two wrapper methods
priceTick and sizeTick.
* Automatic request throttling.
* Optional ``wrapper.tcpDataArrived()`` method;
If the wrapper has this method it is invoked directly after
a network packet has arrived.
A possible use is to timestamp all data in the packet with
the exact same time.
* Optional ``wrapper.tcpDataProcessed()`` method;
If the wrapper has this method it is invoked after the
network packet's data has been handled.
A possible use is to write or evaluate the newly arrived data in
one batch instead of item by item.
Attributes:
MaxRequests (int):
Throttle the number of requests to ``MaxRequests`` per
``RequestsInterval`` seconds. Set to 0 to disable throttling.
RequestsInterval (float):
Time interval (in seconds) for request throttling.
MinClientVersion (int):
Client protocol version.
MaxClientVersion (int):
Client protocol version.
Events:
* ``apiStart`` ()
* ``apiEnd`` ()
* ``apiError`` (errorMsg: str)
