# Your code here - no need to call ib.run()
```

--------------------------------

### Asynchronous Start for IBC

Source: https://ib-api-reloaded.github.io/ib_async/_modules/ib_async/ibcontroller.html

```python
if self._proc:
    return
self._logger.info("Starting")

# map from field names to cmd arguments; key=(UnixArg, WindowsArg)
args = dict(
    twsVersion=("", ""),
    gateway=('--gateway', '/Gateway'),
    tradingMode=('--mode=', '/Mode:'),
    twsPath=('--tws-path=', '/TwsPath:'),
    twsSettingsPath=('--tws-settings-path=', ''),
    ibcPath=('--ibc-path=', '/IbcPath:'),
    ibcIni=('--ibc-ini=', '/Config:'),
    javaPath=('--java-path=', '/JavaPath:'),
    userid=('--user=', '/User:'),
    password=('--pw=', '/PW:'),
    fixuserid=('--fix-user=', '/FIXUser:'),
    fixpassword=('--fix-pw=', '/FIXPW:'),
    on2fatimeout=('--on2fatimeout=', '/On2FATimeout:'),
)

# create shell command
cmd = [
    (
        f"{self.ibcPath}\\scripts\\StartIBC.bat"
        if self._isWindows
        else f"{self.ibcPath}/scripts/ibcstart.sh"
    )
]
for k, v in util.dataclassAsDict(self).items():
    arg = args[k][self._isWindows]
    if v:
        if arg.endswith("=") or arg.endswith(":"):
            cmd.append(f"{arg}{v}")
        elif arg:
            cmd.append(arg)
        else:
            cmd.append(str(v))
```

--------------------------------

### Clone ib_async Repository

Source: https://ib-api-reloaded.github.io/ib_async/index.html

Clones the `ib_async` project repository from GitHub to a local machine. This is the first step in setting up the project for local development.

git clone https://github.com/ib-api-reloaded/ib_async.git
cd ib_async
```

### Create a Bracket Order

Source: https://ib-api-reloaded.github.io/ib_async/index.html

Illustrates the setup for a bracket order, which includes a parent order and associated stop-loss and take-profit orders. Note that `transmit=False` is used for parent and child orders, requiring explicit transmission.

```python
from ib_async import *

ib = IB()
ib.connect('127.0.0.1', 7497, clientId=1)

# Create a bracket order (entry + stop loss + take profit)
contract = Stock('TSLA', 'SMART', 'USD')

# Parent order
parent = LimitOrder('BUY', 100, 250.00)
parent.orderId = ib.client.getReqId()
parent.transmit = False

# Stop loss
stopLoss = StopOrder('SELL', 100, 240.00)
stopLoss.orderId = ib.client.getReqId()
stopLoss.parentId = parent.orderId
stopLoss.transmit = False

```

--------------------------------

### Get All Executions

Source: https://ib-api-reloaded.github.io/ib_async/_modules/ib_async/ib.html

    """List of all executions from this session."""
    return list(fill.execution for fill in self.wrapper.fills.values())
```

--------------------------------

### Get All Orders

Source: https://ib-api-reloaded.github.io/ib_async/_modules/ib_async/ib.html

Returns a list of all orders from the current session, extracting the order object from each trade.

```python
def orders(self) -> list[Order]:
    """List of all orders from this session."""
    return list(trade.order for trade in self.wrapper.trades.values())
```

--------------------------------

### Initialize ib_async Client

Source: https://ib-api-reloaded.github.io/ib_async/_modules/ib_async/client.html

Initializes the asynchronous client with a wrapper object. It sets up event handlers and internal state for connection management and request throttling.

```python
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.

    Parameters:
      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)
      * ``throttleStart`` ()
      * ``throttleEnd`` ()
