Indicator correctly draws only on lower intervals and live data

[dmdamiyo]

Hi,

I wanted to develop an indicator that when RSI is below 30 on H1 interval I can see blue arrows on other intervals - ex. M5, M15, H1, even H4.

But I have a problem - on live data it draws correctly - but when I attach my idicator to the window it doesn't show arrows in some places on H1 interval and H4.

In strategy tester I see that problematic periods are when RSI was below 30 only for short amount of time, for example 3:25 - 3:50. If that's the case it doesn't show the arrow on H1 interval. So what I tried to do is to check if RSI was below of 30 at any moment in this hour and if so I always draw an arrow even when RSI no logner is below 30.

It works on live data (in the tester). But after attaching my indicator to the window I still don't see arrows in the places when rsi was only briefly below 30. Maybe I should remember here about something? Or I have a flaw in my logic?

datetime lastChangeTime=EMPTY_VALUE;
int lastDirection=EMPTY_VALUE;

bool isFirstChangeInTheHour(datetime currentDate)
  {
   if(lastChangeTime==currentDate)
     {
      return false;
     }

   return true;
  }

void markChange(datetime currentDate)
  {
   lastChangeTime=currentDate;
  }

// in oncalulate

for(int barNumber=0; barNumber<limit; barNumber++)
     {
      //For every bar
      int h1BarIndex=iBarShift(NULL,PERIOD_H1,Time[barNumber]);
      int h1Direction = getDirection(h1BarIndex); //this check for now if RSI is below 30, maybe the problem lies in the interval//

      // this is what I tried to fix the issue

      // get opening time of a bar
      datetime beginningOfH1 = iTime(Symbol(),PERIOD_H1,h1BarIndex);
      if(isFirstChangeInTheHour(beginningOfH1))
        {
         // if it changes for the first time in this hour
         if(h1Direction==GOING_DOWN)
           {
            // prevent from drawing two overlapping shapes
            lastDirection=GOING_DOWN;
            Alert("First change in"+beginningOfH1+" date: "+Time[barNumber]);
            arrowUp[barNumber]=EMPTY_VALUE;
            arrowNothing[barNumber]=EMPTY_VALUE;
            arrowDown[barNumber]=0;
            markChange(beginningOfH1);
           }
         else if(h1Direction==GOING_UP)
           {
            lastDirection=GOING_UP;
            Alert("First change in"+beginningOfH1+" date: "+Time[barNumber]);
            arrowUp[barNumber]=0;
            arrowDown[barNumber]=EMPTY_VALUE;
            arrowNothing[barNumber]=EMPTY_VALUE;
            markChange(beginningOfH1);
           }
         else if(h1Direction==NOTHING)
           {
            lastDirection=NOTHING;
            if(arrowDown[barNumber]==EMPTY_VALUE && arrowUp[barNumber]==EMPTY_VALUE)
              {
               arrowNothing[barNumber]=0;
              }
           }

        }
      else
        {
         // Use global value after the first change was noticed
         // so till the end of the hour we draw the same shape
         if(lastDirection==GOING_DOWN)
           {
            arrowDown[barNumber]=0;
            arrowUp[barNumber]=EMPTY_VALUE;
            arrowNothing[barNumber]=EMPTY_VALUE;
           }
         else if(h1Direction==GOING_UP)
           {
            arrowUp[barNumber]=0;
            arrowDown[barNumber]=EMPTY_VALUE;
            arrowNothing[barNumber]=EMPTY_VALUE;
           }
         else if(h1Direction==NOTHING)
           {
            if(arrowDown[barNumber]==EMPTY_VALUE && arrowUp[barNumber]==EMPTY_VALUE)
              {
               arrowNothing[barNumber]=0;
              }
           }
        }
