Need help converting a formula from Tradestation or MetaStock to MetaTrader

New comment
 

I have an indicator that I am trying to write.  I have the formula in both Tradestation format and MetaStock format.  Can someone help me convert this to MetaTrader please?  I have tried, but it only prints flat lines on the bottom of the screen.


Tradestation Format:

Create two functions in EasyLanguage first.  The first is a 9-period momentum study of RSI.  This can be written as

RSIDelta = MOMENTUM(RSI(CLOSE,14),9)

Then a smoothed short period RSI is created,

RSIsma = AVERAGE(RSI(CLOSE,3),3)

The indicator can then be created:

INDICATOR:  MY INDICATOR

Plot1(RSIDelta+RSIsma,"Plot1");

Plot2(average((plot1),13),"Plot2");

Plot3(average((plot1),33),"Plot3");


MetaStock Format:

A = RSI(14)-Ref(RSI(14),-9)+Mov(RSI(3),3,S);

Plot1 = Mov(A,13,S);

Plot2 = Mov(A,33,S);

A;Plot1;Plot2;



Here's what I've gotten so far:

#property indicator_separate_window

#property indicator_buffers 3

#property indicator_color1 DodgerBlue

#property indicator_color2 Lime

#property indicator_color3 Yellow

//---- buffers

double PlotBuffer1[];

double PlotBuffer2[];

double PlotBuffer3[];


int counted_bars;

   SetIndexBuffer(0,PlotBuffer1);

   SetIndexBuffer(1,PlotBuffer2);

   SetIndexStyle(2,DRAW_LINE);   // Plot3

   SetIndexBuffer(2,PlotBuffer3);

   SetIndexDrawBegin(0,0);

   SetIndexDrawBegin(1,0);

   SetIndexDrawBegin(2,0);

   

   IndicatorShortName("MyIndicator");

   counted_bars=IndicatorCounted();

   return(0);

  }

  }

int start()

  {

   double RSIDelta;

   double RSIsma;

   int pos = counted_bars;

//----

//   Alert("position:  " + pos);

//   Alert("current bar close:  " + Close[pos]);

//   Alert("bars:  " + Bars);

   

   RSIDelta = iMomentum(NULL,0,9,iRSI(NULL,0,14,PRICE_CLOSE,0),0);

   RSIsma = iMA(NULL,0,3,0,MODE_SMMA,iRSI(NULL,0,3,PRICE_CLOSE,0),0);

   PlotBuffer1[counted_bars] = RSIDelta+RSIsma;

   PlotBuffer2[counted_bars] = iMA(NULL,0,13,0,MODE_SMA,PlotBuffer1,0);

   PlotBuffer3[counted_bars] = iMA(NULL,0,33,0,MODE_SMA,PlotBuffer1,0);

   

   pos--;

//----

   return(0);

  }

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


Any help will be greatly appreciated.  Thanks.

 

you will have to use iMomentumOnArray & iMAOnArray instead.
