Hi, I am new to coding, I have developed a momentum indicator in EasyLanguage for TradeStation (simple one really). and Now that I want to move to SierraChart, I faced problem trying to replicate the code for ACSIL

Here is my EasyLanguage code:

HTML Code:
inputs: 
double length(14), 
double calcLength(5), 
double smoothLength(3);

vars: 
double s(0), 
double MA(0), 
double Main(0), 
double Signal(0), 
double ss(0),
double len(0);

len = length;

s = 0;
for ss = 0 to (len - 1) begin
	if close > open[ss] then s = s + 1;
	if close < open[ss] then s = s - 1;
	//else s = 0;
	 

end;

MA = XAverage(s, calcLength);
Main = XAverage(MA, smoothLength);
Signal = XAverage(Main, smoothLength);

plot1(Main, "Main", iff(Main > Signal, green, red));
plot2(Signal, "Signal", iff(Main > Signal, green, red));
plot3(0, "ZeroLine", Darkgray);

plot4(length, "UpperLine", red);
plot5(-length, "LowerLine", green);

plot6(length * 0.8, "Overbought", red);
plot7(-length * 0.8, "Oversold", green);


And Here is my endless trial of replicating it to SierraChart ACSIL, I really appreciate any help cause I am going nuts with this thingy

HTML Code:
SCDLLName("TrueMomentum_H")

SCSFExport scsf_TrueMomentum_H(SCStudyInterfaceRef sc)
{
	SCSubgraphRef Subgraph_Main = sc.Subgraph[0];
	SCSubgraphRef Subgraph_Signal = sc.Subgraph[1];
	SCSubgraphRef Subgraph_ZeroLine = sc.Subgraph[2];
	SCSubgraphRef Subgraph_UpperLine = sc.Subgraph[3];
	SCSubgraphRef Subgraph_LowerLine = sc.Subgraph[4];
	SCSubgraphRef Subgraph_Overbought = sc.Subgraph[5];
	SCSubgraphRef Subgraph_Oversold = sc.Subgraph[6];

	SCInputRef Input_Length = sc.Input[0];
	SCInputRef Input_CalcLength = sc.Input[1];
	SCInputRef Input_SmoothLength = sc.Input[2];

	if (sc.SetDefaults)
	{
		sc.GraphName = "#MyTrueMomentum";

		sc.GraphRegion = 0;
		sc.ValueFormat = 2;
		sc.AutoLoop = 1;

		Subgraph_Main.Name = "Main";
		Subgraph_Main.DrawStyle = DRAWSTYLE_LINE;
		Subgraph_Main.PrimaryColor = RGB(0, 255, 0);
		Subgraph_Main.SecondaryColor = RGB(255, 0, 0);
		Subgraph_Main.SecondaryColorUsed = true;
		Subgraph_Main.DrawZeros = false;

		Subgraph_Signal.Name = "Signal";
		Subgraph_Signal.DrawStyle = DRAWSTYLE_LINE;

		Subgraph_Signal.SecondaryColor = RGB(255, 0, 0);
		Subgraph_Signal.SecondaryColorUsed = true;
		Subgraph_Signal.DrawZeros = false;

		Subgraph_ZeroLine.Name = "ZeroLine";
		Subgraph_ZeroLine.DrawStyle = DRAWSTYLE_LINE;
		Subgraph_ZeroLine.PrimaryColor = RGB(169, 169, 169);
		Subgraph_ZeroLine.DrawZeros = true;

		Subgraph_UpperLine.Name = "UpperLine";
		Subgraph_UpperLine.DrawStyle = DRAWSTYLE_LINE;
		Subgraph_UpperLine.PrimaryColor = RGB(255, 0, 0);
		Subgraph_UpperLine.DrawZeros = false;

		Subgraph_LowerLine.Name = "LowerLine";
		Subgraph_LowerLine.DrawStyle = DRAWSTYLE_LINE;
		Subgraph_LowerLine.PrimaryColor = RGB(0, 255, 0);
		Subgraph_LowerLine.DrawZeros = false;

		Subgraph_Overbought.Name = "Overbought";
		Subgraph_Overbought.DrawStyle = DRAWSTYLE_LINE;
		Subgraph_Overbought.PrimaryColor = RGB(255, 0, 0);
		Subgraph_Overbought.DrawZeros = false;

		Subgraph_Oversold.Name = "Oversold";
		Subgraph_Oversold.DrawStyle = DRAWSTYLE_LINE;
		Subgraph_Oversold.PrimaryColor = RGB(0, 255, 0);
		Subgraph_Oversold.DrawZeros = false;

		Input_Length.Name = "Length";
		Input_Length.SetInt(14);
		Input_Length.SetIntLimits(1, MAX_STUDY_LENGTH);

		Input_CalcLength.Name = "Calculation Length";
		Input_CalcLength.SetInt(5);
		Input_CalcLength.SetIntLimits(1, MAX_STUDY_LENGTH);

		Input_SmoothLength.Name = "Smooth Length";
		Input_SmoothLength.SetInt(3);
		Input_SmoothLength.SetIntLimits(1, MAX_STUDY_LENGTH);

		return;
	}

	int len = Input_Length.GetInt();
	SCFloatArrayRef s = sc.Subgraph[7]; // Create an array to store 's' values
	SCFloatArrayRef MA = sc.Subgraph[8]; // Create an array to store 'MA' values
	SCFloatArrayRef Main = sc.Subgraph[9]; // Create an array to store 'Main' values
	SCFloatArrayRef Signal = sc.Subgraph[10]; // Create an array to store 'Signal' values

	s[sc.Index] = 0;
	for (int ss = 0; ss < len; ss++)
	{
		if (sc.Close[sc.Index] > sc.Open[sc.Index - ss])
			s[sc.Index] = s[sc.Index] + 1;
		else if (sc.Close[sc.Index] < sc.Open[sc.Index - ss])
			s[sc.Index] = s[sc.Index] - 1;
		//else
		//	s[sc.Index] = 0;
	}

	MA[sc.Index] = sc.SimpleMovAvg(s, Input_CalcLength.GetInt());
	Main[sc.Index] = sc.SimpleMovAvg(MA, Input_SmoothLength.GetInt());
	Signal[sc.Index] = sc.SimpleMovAvg(Main, Input_SmoothLength.GetInt());

	Subgraph_Main[sc.Index] = Main[sc.Index];
	Subgraph_Signal[sc.Index] = Signal[sc.Index];
	Subgraph_ZeroLine[sc.Index] = 0;
	Subgraph_UpperLine[sc.Index] = len;
	Subgraph_LowerLine[sc.Index] = -len;
	Subgraph_Overbought[sc.Index] = len * 0.8;
	Subgraph_Oversold[sc.Index] = -len * 0.8;
}

Its telling you what is wrong with your code and what line. "note: candidate expects 3 arguments, 2 provided"

You are not providing all required parameters for each function that is throwing an error. See the specs for the Simple Moving Average here
