"Headless Mode" for In-App Scripting and Development

“Somewhat Interactive” Development Mode

As you’re developing apps, it’s sometimes useful to just create a scratch file containing a bit of code that grabs some input. You can watch the information get printed by the async reader loop as it becomes available off the socket, and maybe copy-paste it from the terminal printout do perform some of your exploratory development work.

Simple exploratory example:

import shinybroker as sb
import pandas as pd


con_id = 265598  # AAPL Stock


ib_conn = sb.create_ibkr_socket_conn()
ib_socket = ib_conn['ib_socket']

sb.send_ib_message(
    s=ib_socket,
    msg=sb.req_sec_def_opt_params(
        reqId=1,
        underlyingSymbol="AAPL",
        futFopExchange="",
        underlyingSecType="STK",
        underlyingConId=265598
    )
)

# start_time = datetime.datetime.now()
# while (datetime.datetime.now() - start_time).seconds < timeout:
incoming_msg = sb.read_ib_msg(sock=ib_socket)
sdops = []
while incoming_msg[0] != sb.functionary['incoming_msg_codes'][
    'SECURITY_DEFINITION_OPTION_PARAMETER_END'
]:
    incoming_msg = sb.read_ib_msg(sock=ib_socket)
    if incoming_msg[0] == sb.functionary['incoming_msg_codes'][
        'SECURITY_DEFINITION_OPTION_PARAMETER'
    ]:
    sdops.append(sb.format_sec_def_opt_params_input(sdop=incoming_msg[2:]))

ib_socket.close()


print(
    pd.concat(sdops, ignore_index=True)
    .sort_values('exchange')
)
