Good day guys! Anybody help with my problem regarding RSI value. How to get this 58.31 using mql5. and this code
"CopyBuffer(rsiDefinition,0,0,3,rsiArray);" are giving me the price of the current symbol. I want this 58.31 for the signal of less then 30 and more than 70. thanks in advance.

   double rsi[];
   ArraySetAsSeries(rsi,true);

   int buffer_num = 0;  // indicator buffer number
   int start_pos  = 0;  // start position
   int count      = 3;  // amount to copy

   if(CopyBuffer(indicator_handle,buffer_num,start_pos,count,rsi)!=count)
      return;
   Print(DoubleToString(rsi[0],2));
