Post From: ACSIL - I do not understand how to plot a moving average

Hello, this might be a dumb question, however, I found it difficult to plot a moving average on a chart. I have a very simple study that calculates the diff between the last traded volume at the ask and at the bid. I am trying to make an SMA out of it, I can plot the diff (I have a DOM opened with the last volume studies), but I can't plot the SMA.


#include "sierrachart.h"

SCDLLName("SmaTest")

SCSFExport scsf_SmaTest(SCStudyInterfaceRef sc)
{
SCSubgraphRef SubgraphSMA = sc.Subgraph[0];

SCInputRef Input_SMAPeriod = sc.Input[0];

SCFloatArray IndicatorArray;

if (sc.SetDefaults)
{

sc.GraphName = "Sma plot test";

SubgraphSMA.Name = "SMA";
SubgraphSMA.DrawStyle = DRAWSTYLE_LINE;
SubgraphSMA.DrawZeros = false;

Input_SMAPeriod.Name = "SMA Period";
Input_SMAPeriod.SetInt(10);

}

int Indicator = sc.GetRecentAskVolumeAtPrice(sc.Ask) - sc.GetRecentBidVolumeAtPrice(sc.Bid);

IndicatorArray[IndicatorArray.GetArraySize()] = Indicator;

sc.SimpleMovAvg(
IndicatorArray,
SubgraphSMA,
Input_SMAPeriod.GetInt()
);
}

What am I doing wrong here? I tried to add things like
sc.Subgraph[0][sc.Index] = SubgraphSMA;
but this is not working. As far as I understand, the SMA is computed, but I can't see how I should plot it.

Any help would be really appreciated!

Thank you
