How to use iRSI function to get the value of RSI on the last bar in a chart

[MT5.2014]

Hi guys,

I used iRSI function  in following format

int  iRSI(    string              symbol,            // symbol name    ENUM_TIMEFRAMES     period,            // period    int                 ma_period,         // averaging period    ENUM_APPLIED_PRICE  applied_price      // type of price or handle    );

in an indicator to get the value of RSI on the last bar of a chart, but it did not work, does it need extra code or I am doing something wrong.

Thanks

What didn't work ? Please show your code if you need coding help.

It does not return the value of RSI, it returns 10 even when I changed the symbol or timeframe

#property indicator_chart_window
#property indicator_buffers 1
#property indicator_plots   1
double iRSIBuffer[];
//+------------------------------------------------------------------+
//| Custom indicator iteration function                              |
//+------------------------------------------------------------------+
int OnCalculate(const int rates_total,
                const int prev_calculated,
                const datetime &time[],
                const double &open[],
                const double &high[],
                const double &low[],
                const double &close[],
                const long &tick_volume[],
                const long &volume[],
                const int &spread[])

      
{
         CopyBuffer(iRSI(_Symbol,PERIOD_H4,14,PRICE_CLOSE),0,0,1,iRSIBuffer);
         double irsiv = iRSIBuffer[0];
         Comment (irsiv);

         if(irsiv<30.00)
         {
            Alert("Buy");
         }         
      
   return(rates_total);
}

it shows the comment (irsiv value) correctly, but it does not show the alert correctly (the if clause does not work)

Hi dude, I have the same issue, could you make it work?

What part of the posted code (MT5.2014 2015.06.14 12:09 #3) was unclear?

I'm having the same proble with my code. It just prints out 10.0 constantly, also if I try it with iMA

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

//| Expert initialization function                                   |

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

int OnInit()

  {

//---

   

//---

   return(INIT_SUCCEEDED);

  }

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

//| Expert deinitialization function                                 |

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

void OnDeinit(const int reason)

  {

  }

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

//| Expert tick function                                             |

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

void OnTick()

  {

//---



  

   double rsi = iRSI(NULL,0, 14, PRICE_CLOSE); 

   //double movingAverage = iMA(NULL,0,15,0,MODE_SMA,PRICE_MEDIAN);

   

   Alert(rsi); 

 

   

  }

Skester96: I'm just starting to use MQL5 and when I try to call the rsi, my terminal just prints 10 constanly.

Of course, it does.

1. What does iRSI return?
2. Why are you calling it outside of OnInit?

Unfortunately the example in the documetation is a bit overkill for newbies. I was struggeling with the same issue.

IMHO the following article has a pretty good explanation for this issue:

Have a look into the section: Connecting indicators

You want the rsi value ontick why would anyone want the rsi Oninit <Deleted>?
