It starts from the current candle, since the current candle is not closed, it may repaint.

Try changing your logic and ignore current candle until it is closed, maybe by starting your loop from 1 instead of 0.

//---
   for(int i=1;i<limit;i++)

You have two global variables flag_up and flag_down. The pre-condition is that those variables are from the previous bar.

1. You are counting up, therefor using future values. Even if you count down, you violate the pre-condition when you process bar zero more than once.
2. This means, as is, you can't process bar zero (the forming one,) more than once, ever.
   1. You can put them in a buffer so you can get the previous bar value.
   2. Only process bar zero once (or none.)
   3. Save and restore them when processing bar zero. Example at How to predict RSI Level??? - MQL4 programming forum - Page 2 #11 Lines 131 & 193
      
   4. Use an array (size 2) and use iNS=rates_total-1-iBar, iCur=iNS%2, iPre=!iCur; var[iCur]=function(var[iPre]);. No save/restore required.

I answered your question already. #2

   if(prev_calculated==0) limit = rates_total-2;
   else limit = rates_total - prev_calculated;
//---
   for(int i=limit-1; i>=0; i--)
⋮
   return(rates_total-1);

is also reprocessing bars.

make sure, all var i,  use i+1

example:

arrup[i+1] = low[i+1];

do all var i
