Bug when using cancelPositionsMulti

[mafianekcek]

Hello, I just found a bug when using cancelPositionsMulti (with Advisory demo account). I am not sure where exactly the problem is (thats why I am writing this topic) but basically it doesnt work and after using this command the whole API breaks (sending random messages to the API etc..)

Here is the script which you can use to reproduce this bug: test.js:

const { IBApi, EventName } = require("@stoqey/ib")

const ib = new IBApi({
    clientId: 1,
    host: "127.0.0.1",
    port: 7497,
})

ib.on(EventName.info, (msg, code) => {
    console.log("INFO", code, msg)
})

ib.on(EventName.error, (err, code, reqId) => {
    console.error("ERROR", reqId, code, err.message)
})

ib.on(EventName.nextValidId, (id) => {
    console.log("nextValidId", id)
})

ib.on(EventName.positionMulti, (reqId, account, modelCode, contract, pos, avgCost) => {
    console.log("positionMulti", reqId, account, modelCode, JSON.stringify(contract), pos)
})

ib.on(EventName.positionMultiEnd, (reqId) => {
    console.log("positionMultiEnd", reqId)

})

ib.connect()

async function delay(ms) {
    const res = await new Promise((resolve, reject) => { setTimeout(() => { return resolve(true) }, ms) })
    return res
}

setTimeout(async() => {
    console.log("reqPositionsMulti 1")
    ib.reqPositionsMulti(1, "DU010", "")

    console.log("Waiting 5 sec...")
    await delay(5000)

    console.log("cancelPositionsMulti 1")
    ib.cancelPositionsMulti(1)

    console.log("reqPositionsMulti 2")
    ib.reqPositionsMulti(2, "DU010", "")

    console.log("Exiting in 5 sec...")
    await delay(5000)
    ib.disconnect()
}, 1000)

test.js output:

The behavior when using the official Python API client is normal, here you can see the script used and the output.

test.py:

import asyncio
from ibapi.client import EClient
from ibapi.wrapper import EWrapper

class IBApiWrapper(EWrapper):
    def __init__(self):
        super().__init__()

class IBApiClient(EClient):
    def __init__(self, wrapper):
        EClient.__init__(self, wrapper)

class IBApiApp(IBApiWrapper, IBApiClient):
    def __init__(self):
        IBApiWrapper.__init__(self)
        IBApiClient.__init__(self, wrapper=self)

    def nextValidId(self, orderId: int):
        super().nextValidId(orderId)
        self.nextOrderId = orderId
        print(f"Next valid order ID: {orderId}")

    def positionMulti(self, reqId, account, modelCode, contract, pos, avgCost):
       print("PositionMulti. reqId:", reqId, "Account:", account, "ModelCode:", modelCode, "Contract:", contract, ",Position:", pos, "AvgCost:", avgCost)         

    def positionMultiEnd(self, reqId):
        print("PositionMultiEnd. reqId:", reqId)  

async def run_loop(app):
    while True:
        app.run()

async def main():
    app = IBApiApp()
    app.connect('127.0.0.1', 7497, clientId=1)

    loop = asyncio.get_event_loop()
    loop.run_in_executor(None, app.run)

    await asyncio.sleep(1)

    print("reqPositionsMulti 1")
    app.reqPositionsMulti(1, "DU010", "")

    print("Waiting 5 sec...")
    await asyncio.sleep(5)

    print("cancelPositionsMulti 1")
    app.cancelPositionsMulti(1)

    print("reqPositionsMulti 2")
    app.reqPositionsMulti(2, "DU010", "")

    print("Exiting in 5 sec...")
    await asyncio.sleep(5)
    app.disconnect()

asyncio.run(main())

test.py output:

Could you please check this issue? Thank you <3

Hello, Thanks for your documented bug report. I've been able to reproduce the problem; but at the moment I don't see any reason for this as those API calls implementation are quite basic. I will look at this deeper when I have some free time. Regards

I got it! :) I will publish a fix in the next few days
