Expected Behavior

The algorithm state matches the IB portfolio,

Actual Behavior

We have observed the following case:

No positions at 5:21Z:

2024-11-26T05:21:37.3783447Z TRACE:: InteractiveBrokersBrokerage.HandlePortfolioUpdates(): Contract: FUT MNQ USD , ConId: 654503320, Position: 0, MarketPrice: 20873.5, MarketValue: 0, AverageCost: 0, UnrealisedPnl: 0, RealisedPnl: 0, AccountName: U8888888

Sell 1 unit at 14:30:00Z

2024-11-27T14:30:01.0118024Z TRACE:: LiveTradingResultHandler.OrderEvent(): Time: 11/27/2024 14:30:01 OrderID: 51 EventID: 2 Symbol: MNQ20Z24 Status: Invalid Quantity: -1 Message: 201 - Order rejected - reason:The Available Funds in your Commodities segment are insufficient to cover the change in the margin requirements in your Commodities segment should this order execute.

Origin: [Id=52] IBPlaceOrder: MNQ20Z24 (FUT MNQ USD CME 20241220 0 ) BrokerId: 52

By then, IB tell us there is an open short position.

2024-11-27T14:30:01.5744480Z TRACE:: InteractiveBrokersBrokerage.HandlePortfolioUpdates(): Contract: FUT MNQ USD , ConId: 654503320, Position: -1, MarketPrice: 20936.9003906, MarketValue: -41873.8, AverageCost: 41873.88, UnrealisedPnl: 0, RealisedPnl: 0.08, AccountName: U8888888

At 16:45, we place an order to open a long position:

2024-11-27T16:45:00.2486565Z TRACE:: LiveTradingResultHandler.OrderEvent(): Time: 11/27/2024 16:45:00 OrderID: 53 EventID: 2 Symbol: MNQ20Z24 Status: Filled Quantity: 1 FillQuantity: 1 FillPrice: $20725.75 OrderFee: 0.62 USD Message: Interactive Brokers Order Fill Event BrokerId: 54

which closes the position:

2024-11-27T16:45:01.2083719Z TRACE:: InteractiveBrokersBrokerage.HandlePortfolioUpdates(): Contract: FUT MNQ USD , ConId: 654503320, Position: 0, MarketPrice: 20726.25, MarketValue: 0, AverageCost: 0, UnrealisedPnl: 421.76, RealisedPnl: 0, AccountName: U8888888

We should see the mismatch that occurred at 2024-11-27T14:30:01.5744480Z.
