When submitting an updated order using PlaceOrder the order is not updated and the IB Gateway returns "Duplicate order id"

Referring to this section from IB's docs about modifying orders:
Modifying Orders

Is it possible to modify an order?

Hi,

When I'm trying to place a simple order with OrderType of Market Order and Limit Order, they both returned with alert message: "Order processing failed. Algorithm definition not found. Code=439. Id=1180."
var order = new Order { TradeAction = TradeAction.Buy, TotalQuantity = 100, OrderType = OrderType.Market };
Highly appreciate for any clues.

Market data from RequestHistoricalData has a lower resolution than the one in TWS.

Inspecting a specific bar in TWS displays higher res data than the bar data received using the API. Is the data rounded somewhere along the way?

        var contract = new Contract
        {
            SecurityType = InterReact.StringEnums.SecurityType.Stock,
            Symbol = "MSFT",
            Currency = "USD",
            Exchange = "SMART"
        };

        //client.Request.RequestCurrentTime();

        //var test = await client.Services.HistoricalDataObservable(contract);

        var contractDetailsList = await client.Services.ContractDetailsObservable(contract);

        var contractDetails = contractDetailsList.Single();

Var contractDetails returns zero.

When I debug the solution, IB gateway log shows the contract detail is returned, yet the program doesn't seem to hit the contractDetail.

Any idea?

Thanks.

I updated to the latest and tried using the OpenOrdersObservable and it doesn't appear to be handling/receiving the OrderStatusReports. A new order will cause a "Submitted" OrderStatusReport to be received. When it's cancelled a "Cancelled" report should be received.

In HistoricalBarSize class, OneSecond is set as "1 sec". However as stated in IBKR error message:
"Historical data bar size setting is invalid. Legal ones are: 1 secs, 5 secs, 10 secs, 15 secs, 30 secs, 1 min, 2 mins, 3 mins, 5 mins, 10 mins, 15 mins, 20 mins, 30 mins, 1 hour, 2 hours, 3 hours, 4 hours, 8 hours, 1 day, 1W, 1M--"
It is supposed to be set to "1 secs"

Semaphore is not compatible with Linux so a migration to the use of Mutex or TaskCompletionSource would be a good thing.

Hi!

It looks like IB has updated the format for HistoricalDataBar. What can see there no longer is a gap that was handled like:

r.ReadString(); /* string hasGaps */

This makes the line after crash:

Count = r.ReadInt();

Is it possible to find the IB specs for the different messages?

It would be nice to have a NuGet distribution.

when creating new order and trying to place it
Order neworder = new Order();
neworder.OrderType = OrderType.Limit;
neworder.TradeAction = TradeAction.Buy;
neworder.LimitPrice = 1;
neworder.TimeInForce = TimeInForce.Day;
neworder.TotalQuantity = 1;

        neworder.AlgoStrategy  = "Adaptive";
        neworder.AlgoParams.Add(new Tag("adaptivePriority", "Patient"));  <-- here 

get error

Alert: {RequestId:1823, OrderId:1823, Code:320, Message:"Error reading request.Message id 1823. Unable to parse data. java.lang.NumberFormatException: For input string: "Patient"", AlertType:HasId}
