int ArrayMaximum( double array[], int count=WHOLE_ARRAY, int start=0)

Searches for the element with maximum value. The function returns position of this maximum element in the array.

It will be the index of the element, not the element itself.

zzuegg, thanks for the help. I'm beginner, but I'll study how to do that you wrote. I think the first one is easier, but I still not knowing how to implement this in my formula. If possible, give me an example.


Thanks again.


i think option 2 is easier. He already gave you the pseudocode you need. just replace the function header, put in some brackets, and replace RSI(i) with the iRSI function. Pretty straightforward and there's no need to mess with additional arrays. This is how i would do it.

Yeah, I tested it and did not work.

So think for a change
for(int i = limit-1; i>=0; i--) // Count down for one pass 
     RSI_Buffer[i]=iRSI(NULL,0,periodoRSI,PRICE_CLOSE,i);
//   a1_Buffer[i] = ArrayMaximum(RSI_Buffer, 20, i);
     a1_Buffer[i] = RSI_Buffer[ArrayMaximum(RSI_Buffer, 20, i)];

Thanks... worked very well this change! I didn't know that it was allowable.

a1_Buffer[i] = RSI_Buffer[ArrayMaximum(RSI_Buffer, 20, i)];

Great job. I will finish the indicator and post here.

Thanks everybody! I finished the indicator.

Hi guys,

I am a newbie and I need a code to determine the value of RSI at the end of each period (at the end of M1, M5, ....)

Thanks in advance

So use the code published in this thread . . . .  if that doesn't meet your needs you are off topic and shouldn't be posting in this thread.

I want to determine the value of a custom indicator at the end of each period (at the end of M1, M5, ....), 

I want to find the value of X= value of the buffer at the end of each periode (M1, M5, M15,....)

 

Please help
