Hi All,

I am new to MQL world and need some assistance.

I need to find out which if price in the last 10 candles has touched my 20 Moving average.

I am not sure what is the best way to write this and how to do it. Can you please help?


Thanks

iHighest

Returns the shift of the maximum value over a specific number of bars depending on type.

int  iHighest( 
   string           symbol,          // symbol 
   int              timeframe,       // timeframe 
   int              type,            // timeseries 
   int              count,           // cont 
   int              start            // start 
  );

Parameters

symbol

[in]  Symbol the data of which should be used for search. NULL means the current symbol.

timeframe

[in]  Timeframe. It can be any of ENUM_TIMEFRAMES enumeration values. 0 means the current chart timeframe.

type

[in]  Series array identifier. It can be any of the Series array identifier enumeration values.

count=WHOLE_ARRAY

[in]  Number of bars (in direction from the start bar to the back one) on which the search is carried out.

start=0

[in]  Shift showing the bar, relative to the current bar, that the data should be taken from.

Returned value

The shift of the maximum value over a specific number of bars or -1 if error. To check errors, one has to call the GetLastError() function.

Example:

 double val; 
//--- calculating the highest value on the 20 consecutive bars in the range 
//--- from the 4th to the 23rd index inclusive on the current chart 
   int val_index=iHighest(NULL,0,MODE_HIGH,20,4); 
   if(val_index!=-1) val=High[val_index]; 
   else PrintFormat("Error in call iHighest. Error code=%d",GetLastError());

Example:


Mohammed, that does give me the value of the highest candle but what I after is which number candle is the highest. I.e it can be Candle 4 or 5 or 7 or 9, that is the sort of information I am after

For each of the 10 candles, get the high, the low and the MA. price touched if H >= MA && MA >= L

Thanks Whraeder1, is there a loop that I can write to get the MA value of the last 10 cancles and compare with the value of last 10 Moving average value? That would make my code a lot simpler and shorter else I will have to write a long long code.

void OnStart()
{

   int high_touch_count=0; // count of the number of bars that is greater than the MA
   MqlRates rates[];
   ArraySetAsSeries(rates,true);
   CopyRates(Symbol(),Period(),0,10,rates);
   
   double ma[10];
   
   for(int i=0;i<10;i++)
      ma[i] = iMA(Symbol(),Period(),20,0,MODE_SMA,PRICE_CLOSE,i);
   
   for(int i=0;i<ArraySize(rates);i++)
   {
      if(rates[i].high >= ma[i] && rates[i].low < ma[i])
         high_touch_count++;
   }
}

  1. Why did you post your MT4 question in the Root / MT5 EA section instead of the MQL4 section (bottom of the Root page?)General rules and best pratices of the Forum. - General - MQL5 programming forum
  2. What do you mean "is there a loop?" There isn't, until you write one!
       int nTouch=0;
       for(int i=0;i<10;i++){
          double ma = iMA(Symbol(),Period(),20,0,MODE_SMA,PRICE_CLOSE,i);
          if(High[i] >= ma && Low[i] < ma) ++nTouch;
       }
    Was that so hard?
