Clicking refresh sometimes leads to different custom indicator results

Question

I have a weird occurence that I cannot figure out. I developed a custom indicator that calculates an index following which I will make trade decisions. The indicator uses three time periods to check whether the trend is stable or not. The first is a one minute, second a 5 minute and lastly a 30 minute time period. I calculate the appropriate bar from which to check the larger time periods so that they correspond with the one minute bar.

My testing shows that the numbers are calculated correctly.

This indicator is attached to a one minute chart. A lot of times, I will right click and choose refresh and the indicator will change over the last 5 - 10 minutes! I cannot find a reason why it would do that. I tried clicking refresh after every one minute bar and sometimes it would change and other times not. However, even if I click after every minute on a chart, sometimes the changes will be 5 - 10 minutes back.

Can you please help me?

I include my code for your kind help:

  {
   int i,                        // Bar index                           
       iLook = 0,
       iCurrMinute = 0,
       iMinFloor = 0,
       iMinsAdd = 0,
       Counted_bars,                // Number of counted bars
       iCalcVal,
       iTrendConsistency;

      Trend_Consistency[i]= iTrendConsistency;

      i--;                          // Calculating index of the next bar
     }

ps: boolIncl1Min is always true..
