Hello fellow traders,

I am trying to modfiy an existing order with my code, but I always get:

and my code looks like this:

for pos in ib.openOrders():
    ids.append(pos.orderId)
    if pos.permId == l_TakeProfitOrder['permId']:
        takeProfitOrder = pos
    if pos.permId == l_StoppLossOrder['permId']:
        stoppLossOrder = pos


quantity = takeProfitOrder.totalQuantity
takeProfitOrder.lmtPrice -=  - 0.2
takeProfitOrder.orderId += 1
ib.placeoder(contract, takeProfitOrder)

The contract I am trying to modify is created somewhere else, but the code is pretty much loading an existing order, then modifying the lmtPrice and the OrderId because I also get a different failure code when I keep the same OrderID. But also modyfing the Id before updating the trade also does not work.

Would really love some advice :)
