Calculation difference between Indicator and EA

[[Deleted]]

I have code an indicator that works properly. However, when I place part of the calculation into an EA I get different values.
I have isolated the problem to my SignalBuffer variable. I get different values in the EA than in the indicator.

The indicator value is the correct value. The relevant code snippets are shown below. The only difference I see is the buffer

definitions. Is EA calculation behavior different from Indicators?

Any help would be appreciated.

//----- Indicator Code
#property indicator_separate_window

double MacdBuffer[];
double SignalBuffer[];

int init()
{
IndicatorBuffers(8);

SetIndexBuffer(6,MacdBuffer); //value not painted
SetIndexBuffer(7,SignalBuffer); //value not painted

return(0);
}
int start()
{
int counted_bars=IndicatorCounted();
int i, pos=Bars-counted_bars-1;
if(counted_bars>0) counted_bars--;
limit=Bars-counted_bars;

for(i=0; i<limit; i++)
{MacdBuffer[i]=iMA(NULL,0,FastEMA,0,MODE_EMA,PRICE_CLOSE,i)-iMA(NULL,0,SlowEMA,0,MODE_EMA,PRICE_CLOSE,i);}
for(i=0; i<limit; i++)
{SignalBuffer[i]=iMAOnArray(MacdBuffer,Bars,SignalEMA,0,MODE_EMA,i);} //different value here
Print(" Sig=",SignalBuffer[0]);
}

//----- EA Code

double MacdBuffer[5000];
double SignalBuffer[5000];

int start()
{
int counted_bars=IndicatorCounted();
int i, pos=Bars-counted_bars-1;
if(counted_bars>0) counted_bars--;
limit=Bars-counted_bars;

for(i=0; i<limit; i++)
{MacdBuffer[i]=iMA(NULL,0,FastEMA,0,MODE_EMA,PRICE_CLOSE,i)-iMA(NULL,0,SlowEMA,0,MODE_EMA,PRICE_CLOSE,i);}
for(i=0; i<limit; i++)
{SignalBuffer[i]=iMAOnArray(MacdBuffer,Bars,SignalEMA,0,MODE_EMA,i);} //different value here
Print(" Sig=",SignalBuffer[0]);
}
