Help - MA Problem

New comment
 

Hi everyone,

I've been trying to code this MA. I'm using 5 different Arrays: 3 for loading the 3 MA points, and 2 for the arrows signal.

But i really can't load the MA points into the ShortBuffer[], MediumBuffer[] and LongBuffer[]. When i test it what i get is always 0 for every [i] value. I don't know what i'm doing wrong. Can anyone help me with this.

Many thanks in advance.

I show you my code:

#property indicator_chart_window
#property indicator_buffers 2
#property indicator_color1 Blue
#property indicator_color2 Red

extern int ShortPeriod = 5;
extern int ShortPeriodMethod = 0; //0=sma, 1=ema, 2=smma, 3=lwma
extern int ShortPeriodApplyTo = 0; //0=PRICE_CLOSE, 1=PRICE_OPEN, 2=PRICE_HIGH, 3=PRICE_LOW, 4=PRICE_MEDIAN, 5=PRICE_TYPICAL, 6=PRICE_WEIGHTED

extern int MediumPeriod = 20;
extern int MediumPeriodMethod = 0; //0=sma, 1=ema, 2=smma, 3=lwma
extern int MediumPeriodApplyTo = 0; //0=PRICE_CLOSE, 1=PRICE_OPEN, 2=PRICE_HIGH, 3=PRICE_LOW, 4=PRICE_MEDIAN, 5=PRICE_TYPICAL, 6=PRICE_WEIGHTED

extern int LongPeriod = 50;
extern int LongPeriodMethod = 0; //0=sma, 1=ema, 2=smma, 3=lwma
extern int LongPeriodApplyTo = 0; //0=PRICE_CLOSE, 1=PRICE_OPEN, 2=PRICE_HIGH, 3=PRICE_LOW, 4=PRICE_MEDIAN, 5=PRICE_TYPICAL, 6=PRICE_WEIGHTED

//---- input parameters
//---- buffers

double UpBuffer[];
double DnBuffer[];
double ShortBuffer[];
double MediumBuffer[];
double LongBuffer[];

SetIndexStyle(0,DRAW_ARROW,EMPTY,1);
SetIndexBuffer(0,UpBuffer);
SetIndexArrow(0,233);
SetIndexLabel(0,"Up Signal");

SetIndexStyle(1,DRAW_ARROW,EMPTY,1);
SetIndexBuffer(1,DnBuffer);
SetIndexArrow(1,234);
SetIndexLabel(1,"Down Signal");

}

//+------------------------------------------------------------------+
int start()
{

int limit;
int counted_bars=IndicatorCounted();
//---- check for possible errors
if(counted_bars<0) return(-1);
//---- the last counted bar will be recounted
if(counted_bars>0) counted_bars--;
limit=Bars-counted_bars;
//---- main loop
for(int i=0; i<limit; i++)
{

ShortBuffer[i]= iMA(NULL,0,ShortPeriod,0,ShortPeriodMethod,ShortPeriodApplyTo,i);


MediumBuffer[i]= iMA(NULL,0,MediumPeriod,0,MediumPeriodMethod,MediumPeriodApplyTo,i);


LongBuffer[i]= iMA(NULL,0,LongPeriod,0,ShortPeriodMethod,ShortPeriodApplyTo,i);

...

...
}
return(0);
}

 

How big are ShortBuffer, MediumBuffer and LongBuffer?

Hi Phy,

Thanks for your reply.

I didn't define it...

But it would be (=limit).

Did you find something?

Thanks once more.

 
Well, define the buffer sizes. Try again.

Thanks Phy.

It worked now.

Cheers.
