MACD two line indicator needs alarms

New comment
 

Hello,

I have a MACD two line indicator that I'd like to have some alarms added to it. I'd like to have it both pop up a window and sound an alarm when the blue MACD line crosses a zero level. Here's the indicator code.

#property indicator_separate_window

#property indicator_buffers 3

#property indicator_color1 Blue

#property indicator_color2 Red

#property indicator_color3 Green


//---- input parameters

extern int FastMAPeriod=12;

extern int SlowMAPeriod=26;

extern int SignalMAPeriod=9;


//---- buffers

double MACDLineBuffer[];

double SignalLineBuffer[];

double HistogramBuffer[];


//---- variables

double alpha = 0;

double alpha_1 = 0;


//+------------------------------------------------------------------+

//| Custom indicator initialization function |

//+------------------------------------------------------------------+

int init()

{

IndicatorDigits(MarketInfo(Symbol(),MODE_DIGITS)+1);

//---- indicators

SetIndexStyle(0,DRAW_LINE);

SetIndexBuffer(0,MACDLineBuffer);

SetIndexDrawBegin(0,SlowMAPeriod);

SetIndexStyle(1,DRAW_LINE,STYLE_DOT);

SetIndexBuffer(1,SignalLineBuffer);

SetIndexDrawBegin(1,SlowMAPeriod+SignalMAPeriod);

SetIndexStyle(2,DRAW_HISTOGRAM);

SetIndexBuffer(2,HistogramBuffer);

SetIndexDrawBegin(2,SlowMAPeriod+SignalMAPeriod);

//---- name for DataWindow and indicator subwindow label

IndicatorShortName("MACD("+FastMAPeriod+","+SlowMAPeriod+","+SignalMAPeriod+")");

SetIndexLabel(0,"MACD");

SetIndexLabel(1,"Signal");

//----

alpha = 2.0 / (SignalMAPeriod + 1.0);

alpha_1 = 1.0 - alpha;

//----

return(0);

}

//+------------------------------------------------------------------+

//| Custor indicator deinitialization function |

//+------------------------------------------------------------------+

int deinit()

{

//----

//----

return(0);

}

//+------------------------------------------------------------------+

//| Custom indicator iteration function |

//+------------------------------------------------------------------+

int start()

{

int limit;

int counted_bars = IndicatorCounted();

//---- check for possible errors

if (counted_bars<0) return(-1);

//---- last counted bar will be recounted

if (counted_bars>0) counted_bars--;

limit = Bars - counted_bars;


for(int i=limit; i>=0; i--)

{

MACDLineBuffer[i] = iMA(NULL,0,FastMAPeriod,0,MODE_EMA,PRICE_CLOSE,i) - iMA(NULL,0,SlowMAPeriod,0,MODE_EMA,PRICE_CLOSE,i);

SignalLineBuffer[i] = alpha*MACDLineBuffer[i] + alpha_1*SignalLineBuffer[i+1];

HistogramBuffer[i] = MACDLineBuffer[i] - SignalLineBuffer[i];

}

//----

return(0);

}

//+------------------------------------------------------------------+

Any help would be greatly appreciated.

Here's the indicator code.

Any help would be greatly appreciated.

  1. For large amounts of code, attach it
  2. Since there are no slaves here, there are only two choices: learn to code or pay someone. We're not going to code it FOR you. We are willing to HELP you. Post your attempt and the nature of your problem.
