RSI entry.

New comment

Hello I am requesting your help on this piece of code. The idea is the EA should open both long and sell when the rsi is at 50 level. Note 50 level not greater or less than the level. Below is my code but if I use the equals sign (==) the orders are not triggered. Someone help

string GetEntrySignal()
 {
       string signal = "";
       double prev_rsi = 0;
       double curr_rsi = 0;
    
       double rsi = iRSI(_Symbol,PERIOD_CURRENT,RSIperiod,RSIprice,0);
     
       //buy
      if(rsi == rsi_level) signal = BUYSIGNAL;
      
      //sell
      if(rsi == rsi_level)signal= SELLSIGNAL;
      
   
     
                                         
               
       return signal;
 }  
      if(rsi == rsi_level) signal = BUYSIGNAL;

Doubles are rarely equal. Understand the links in:

Like William rightly said, the probability of getting rsi == 50 is low 
You can try coding it as a cross , that’s what I do
