How to make this pivot indicator to plot only HLINES for the month

New comment
 

Attached is the source of this indicator. Currently it makes use of ObjectMove to continuously plot the pivot levels. I'm trying to modify this indi so that it plots HLINES (Horizontal lines) for the pivot levels for the past month..

I believe I have to change or replace the ObjectMove instances.. could someone advice on how to do this?

Here's how I want the pivot levels to be displayed: https://www.mql5.com/en/charts

Nothing attached. Stop using objects and use your buffers. Fix the indicator so it works on ANY timeframe
Your code
   for(i=limit-1; i>=0; i--)

            if(TimeDay(Time[i])<=3 && TimeDay(Time[i+1])>=26)

                    this_month_open=Open[i];       // and when i=First of the month
                    P=(last_month_high+last_month_low+last_month_close)/3;
          R1=(2*P)-last_month_low;
          S1=(2*P)-last_month_high;
