Open only one position (openApiPy)

Hi,

You can use a global variable to check if the position is already opened or not, ex:

isPositionsRequestSent = False
def onMessageReceived(client, message): # Callback for receiving all messages
    if message.payloadType in [ProtoHeartbeatEvent().payloadType, ProtoOAAccountAuthRes().payloadType, ProtoOAApplicationAuthRes().payloadType, ProtoOASymbolsListRes().payloadType, ProtoOAGetTrendbarsRes().payloadType]:
        return
    print("\nMessage received: \n", Protobuf.extract(message))
    
    
    if message.payloadType == ProtoOAExecutionEvent().payloadType:
        print("Execution event received")
        executionEvent = Protobuf.extract(message)
        print(executionEvent.position.positionId)
        positionId = executionEvent.position.positionId
        
      
    if isPositionsRequestSent is False:
        global isPositionsRequestSent
        isPositionsRequestSent = True
        symbolId = 1106
        clientMsgId = None
        volume = 2

        request = ProtoOANewOrderReq()
        request.ctidTraderAccountId = currentAccountId

        request.symbolId = int(symbolId)
        request.orderType = ProtoOAOrderType.MARKET
        request.tradeSide = ProtoOATradeSide.SELL
        request.volume = int(volume) * 100 


        deferred = client.send(request, clientMsgId = clientMsgId)
        deferred.addErrback(onError)

There are other solutions too, but this one is simplest one, it all depends on what you want to do and your design and architecture.

It's not something related to Open API or our package, these are basic programming stuff that you should know.

Perfect, thanks, this method worked:

    global isPositionsRequestSent
    if isPositionsRequestSent is False:
        
        isPositionsRequestSent = True
