GetAtmStrategyMarketPosition returning error

[gyilaoliver]

Hi,

i created a strategy that creates Atm strategies.

Position.MarketPosition does not work in this case, so I want to check if I am flat with GetAtmStrategyMarketPosition.

However I get ann error : Value cannot be null. Parameter name : key

I generate a unique atm strategy Id for every trade.

What do i do wrong?

if
         (
                 atmStrategyId != null &&
                      (GetAtmStrategyMarketPosition(atmStrategyId) == MarketPosition.Flat ) &&
                            EMA1[0] > EMA2[0]
                         && EMA2[0] > EMA3[0]
                        )

{
     atmStrategyId = GetAtmStrategyUniqueId();
      atmStrategyOrderId = GetAtmStrategyUniqueId();
 
    
                ChartControl.Dispatcher.InvokeAsync((Action)(() =>
                                            {
                                                NinjaTrader.Gui.Tools.QuantityUpDown quantitySelector = (Window.GetWindow(ChartControl.Parent).FindFirst("ChartTraderControlQuantitySelector") as NinjaTrader.Gui.Tools.QuantityUpDown);

                                                contr = quantitySelector.Value ;    
                                                
                                                AtmStrategyCreate(OrderAction.Buy, OrderType.Market, 0, 0, TimeInForce.Day,
          atmStrategyOrderId,  atmname, atmStrategyId, (atmCallbackErrorCode, atmCallbackId) => {
 
          // checks that the call back is returned for the current atmStrategyId stored
          if (atmCallbackId == atmStrategyId)
          {
              // check the atm call back for any error codes
              if (atmCallbackErrorCode == Cbi.ErrorCode.NoError)
              {
                  // if no error, set private bool to true to indicate the atm strategy is created
                  isAtmStrategyCreated = true;
              }
          }
      });
}​
                    )​

Hello gyilaoliver,

Ensure the isAtmStrategyCreated is returning true first, and that GetAtmStrategyEntryOrderStatus() is entryOrder[2] == Filled to confirm the atm has activated.

If you have multiple entries, you need to track the specific atmStrategyId and isAtmStrategyCreated for that specific entry. You might want to do this in a List<string> and List<bool>.
