Hi Dear,
I have run below code and got an error.I am trying to build automated bot using some indicators. It showing that below function not avaliable. Please guide me to resolve this issue

#include "sierrachart.h"

SCDLLName("Simple Automated System 1")

SCSFExport scsf_SimpleAutomatedSystem(SCStudyInterfaceRef sc)
{
if (sc.SetDefaults)
{
sc.GraphName = "Simple Automated System";
sc.StudyDescription = "Example of a simple automated trading system";
sc.GraphRegion = 0;
sc.AutoLoop = 1;
sc.MaintainAdditionalChartDataArrays = 1;

sc.Subgraph[0].Name = "movingAverage";
sc.Subgraph[0].DrawStyle = DRAWSTYLE_LINE;
sc.Subgraph[0].PrimaryColor = RGB(0,255,0);

sc.Subgraph[1].Name = "buySignal";
sc.Subgraph[1].DrawStyle = DRAWSTYLE_ARROW_UP;
sc.Subgraph[1].PrimaryColor = RGB(255,0,0);

sc.Subgraph[2].Name = "sellSignal";
sc.Subgraph[2].DrawStyle = DRAWSTYLE_ARROW_DOWN;
sc.Subgraph[2].PrimaryColor = RGB(0,255,255);

sc.Input[0].Name = "Period";
sc.Input[0].SetInt(20);

return;
}

SCFloatArrayRef close = sc.Close;
SCFloatArrayRef movingAverage = sc.Subgraph[0].Data;
SCFloatArrayRef buySignal = sc.Subgraph[1].Data;
SCFloatArrayRef sellSignal = sc.Subgraph[2].Data;

int period = sc.Input[0].GetInt(); // Moving average period

sc.SimpleMovAvg(close, movingAverage, period);

// Generate buy and sell signals based on the moving average crossover
buySignal[sc.Index] = close[sc.Index] > movingAverage[sc.Index] && close[sc.Index - 1] <= movingAverage[sc.Index - 1];
sellSignal[sc.Index] = close[sc.Index] < movingAverage[sc.Index] && close[sc.Index - 1] >= movingAverage[sc.Index - 1];

//Create a reference to a persistent integer variable for the order ID so it can be modified or canceled.
int& InternalOrderID = sc.GetPersistentInt(1);

// Create an s_SCNewOrder object.
s_SCNewOrder NewOrder;
NewOrder.OrderQuantity = 1;
// NewOrder.OrderType = SCT_MARKET;

// Buy when the last price crosses the moving average from below.
if (sc.CrossOver(Last, SimpMovAvgSubgraph) == CROSS_FROM_BOTTOM && sc.GetBarHasClosedStatus() == BHCS_BAR_HAS_CLOSED)
{
int Result = sc.BuyEntry(NewOrder);
if (Result > 0) //If there has been a successful order entry, then draw an arrow at the low of the bar.
{
BuyEntrySubgraph[sc.Index] = sc.Low[sc.Index];

// Remember the order ID for subsequent modification and cancellation
InternalOrderID = NewOrder.InternalOrderID;
}
}
// // Place trades based on the generated signals
// if (buySignal[sc.Index])
// {
// sc.BuyMarket(sc.TradeSize, "Buy");
// }
// else if (sellSignal[sc.Index])
// {
// sc.SellMarket(sc.TradeSize, "Sell");
// }
}
