My Indicator doesn't appear on one minute time frames & some of the 5 minutes time frames .. please help

[Forex Analyst]

Hi, every one ..

Kindly be generous with info.

Lately I changed my platform to meta trader 4 & I was struggling to convert my indicators to mql4 ,, as it is a new language to me , so after a lot of work & advises ,, at last I built something but unfortunately there is a little problem as mentioned above in the title, that indicators lines didn't appear on the minute time frames & some of the 5 minutes time frames , I will paste here most of the code , hoping that any gentlemen or ladies of course could  help by telling me what I do wrong ?? how can I correct it.

Note: the four Xes in the equations like this "xxxx" supposed to be cache values, please ignore it, I will replace them later by another values that has meaning.

Fix your broken code. You obviously have a divide by zero.

      double y = ((xxxx[i]-xxxx[i])/(xxxx[i]-xxxx[i])) * xxxx;

Assume that xxxx-xxxx  are like high price - low price , so it can't be equal to zero ever. kindly please take another close look , perhaps there is something else ...

2. xxxx[i]-xxxx[i] is always zero. You didn't say xxxx[i]-yyyy[i] If you want real help post your real code.

   We can't see your broken code.

3. Of course, it can be zero. If you get one tick during the minute chart that is exactly what it will be. There can be minutes between ticks during the Asian session, think M1 chart.
