Can not exercise option by ib.exerciseOptions

[eric0470]

Hi! I am trying to exercise options, but get error:

Test code than I used:

    positions = ib.positions()
    options = []

    for position in positions:
        if isinstance(position.contract, (Option, )):
            options.append(position)

    for option in options:
        ib.exerciseOptions(option.contract, 1, option.position, option.account, 0)

Error form IB:

Error 320, reqId 362349789: Error reading request:Message id 362349789. Unable to parse data. java.lang.NumberFormatException: For input string: "BAC" Peer closed connection

What problem can be with the code?

TWS Version: 976.2h IB Insync Version: 0.9.51

Thank you for the bug report. The client was sending one contract field too many, this should now be fixed in v0.9.52.

Please note that exerciseQuantity should be an int, not a float.

The problem exist if i am using contract provided from ib.postions() like that:

    for position in positions:
        if isinstance(position.contract, (Option, )):
            options.append(position)

    for option in options:
        ib.exerciseOptions(option.contract, 1, option.position, option.account, 0)

I get in TWS this error: Message must contain field #207

But if i create contract using option constructor it exercise options:

 contract = Option('GLD', '20190621', 127, 'C', 'SMART')

Version of ib_insync is updated to 0.9.52

Fix protocol field 207 referers to the securityExchange. Probably contract.exchange has to be set to 'SMART'. It's best to ask IB about this sort of logic.

The problem was with using account in exerciseOptions. If I put there empty string, exercise is executing successfully. I think this is bug in TWS system not in your code.
