You need to enable:

sc.SupportAttachedOrdersForTrading = 1;
sc.SupportTradingScaleIn = 1;

Here is the code which demonstrates this successfully works:

SCSFExport scsf_ACSILTradingTest(SCStudyInterfaceRef sc)
{
  //Define references to the Subgraphs and Inputs for easy reference
  SCSubgraphRef BuyEntrySubgraph = sc.Subgraph[0];
  SCSubgraphRef BuyExitSubgraph = sc.Subgraph[1];
  SCSubgraphRef SellEntrySubgraph = sc.Subgraph[2];
  SCSubgraphRef SellExitSubgraph = sc.Subgraph[3];

  SCInputRef Enabled = sc.Input[0];


  if (sc.SetDefaults)
  {
    // Set the study configuration and defaults.

    sc.GraphName = "Trading Test";

    BuyEntrySubgraph.Name = "Buy Entry";
    BuyEntrySubgraph.DrawStyle = DRAWSTYLE_ARROWUP;
    BuyEntrySubgraph.PrimaryColor = RGB(0, 255, 0);
    BuyEntrySubgraph.LineWidth = 2;
    BuyEntrySubgraph.DrawZeros = false;

    BuyExitSubgraph.Name = "Buy Exit";
    BuyExitSubgraph.DrawStyle = DRAWSTYLE_ARROWDOWN;
    BuyExitSubgraph.PrimaryColor = RGB(255, 128, 128);
    BuyExitSubgraph.LineWidth = 2;
    BuyExitSubgraph.DrawZeros = false;

    SellEntrySubgraph.Name = "Sell Entry";
    SellEntrySubgraph.DrawStyle = DRAWSTYLE_ARROWDOWN;
    SellEntrySubgraph.PrimaryColor = RGB(255, 0, 0);
    SellEntrySubgraph.LineWidth = 2;
    SellEntrySubgraph.DrawZeros = false;

    SellExitSubgraph.Name = "Sell Exit";
    SellExitSubgraph.DrawStyle = DRAWSTYLE_ARROWUP;
    SellExitSubgraph.PrimaryColor = RGB(128, 255, 128);
    SellExitSubgraph.LineWidth = 2;
    SellExitSubgraph.DrawZeros = false;

    Enabled.Name = "Enabled";
    Enabled.SetYesNo(0);
    Enabled. SetDescription("This input enables the study and allows it to function. Otherwise, it does nothing.");


    // This is false by default. Orders will go to the simulation system always.
    sc.SendOrdersToTradeService = false;

    sc.AllowMultipleEntriesInSameDirection = true;
    sc.MaximumPositionAllowed = 20;

    sc.SupportReversals = false;
    sc.AllowOppositeEntryWithOpposingPositionOrOrders = false;

    // This variable controls whether to use or not use attached orders that are configured on the Trade Window for the chart.
    sc.SupportAttachedOrdersForTrading = true;

    //This variable controls whether to use the "Use Attached Orders" setting on the Trade Window for the chart
    sc.UseGUIAttachedOrderSetting =false;

    sc.CancelAllOrdersOnEntriesAndReversals= false;
    sc.AllowEntryWithWorkingOrders = true;
    sc.CancelAllWorkingOrdersOnExit = true;
    sc.AllowOnlyOneTradePerBar = false;

    //This needs to be set to true when a trading study uses trading functions.
    sc.MaintainTradeStatisticsAndTradesData = true;

    sc.AutoLoop = true;
    sc.GraphRegion = 0;

    // During development set this flag to 1, so the DLL can be modified. When development is completed, set it to 0 to improve performance.
    sc.FreeDLL = 0;

    return;
  }

  //These must be outside of the sc.SetDefaults code block
  sc.SupportTradingScaleIn = 1;
  sc.SupportTradingScaleOut = 0;


  if (!Enabled.GetYesNo())
    return;

  if ( sc.LastCallToFunction )
    return;//nothing to do


  // Run the below code only on the last bar
  if (sc.Index < sc.ArraySize-1)
    return;


  // Create an s_SCNewOrder object.
  s_SCNewOrder NewOrder;
  NewOrder.OrderQuantity = 2;
  NewOrder.OrderType = SCT_MARKET;


  int Result =sc.BuyEntry(NewOrder);
  if (Result > 0) //If there has been a successful order entry
  {
    BuyEntrySubgraph[sc.Index] = sc.Low[sc.Index];

  }
}
