Can't get Indicator pivot points to match on EA code - mql4

Question

I've been messing around with the Camarilla Indicator and I wanted to get the main pivot values for my EA, can I use iCustom() for that? or should I just pass the code to the EA? but where exactly would I place it? I tried to place it on the onTick() but with a condition of only calculating the pivots when there is a new daily candle, but the values most of the times don't match.
void OnTick()
{
static datetime today;
if (today != iTime (Symbol(), PERIOD_D1, 0))
{
today = iTime (Symbol(), PERIOD_D1, 0);
int counted_bars=IndicatorCounted();
//---- TODO: add your code here
int cnt=720;
//---- exit if period is greater than daily charts
if(Period() > 1440)
{
Print("Error - Chart period is greater than 1 day.");
}
//---- Get new daily prices & calculate pivots
day_high=0;
day_low=0;
yesterday_open=0;
today_open=0;
cur_day=0;
prev_day=0;
while (cnt!= 0)
{
if (TimeDayOfWeek(Time[cnt]) == 0)
{
cur_day = prev_day;
}
else
{
cur_day = TimeDay(Time[cnt]- (GMTshift*3600));
}
if (prev_day != cur_day)
{
yesterday_close = Close[cnt+1];
today_open = Open[cnt];
yesterday_high = day_high;
yesterday_low = day_low;
day_high = High[cnt];
day_low = Low[cnt];
prev_day = cur_day;
}
if (High[cnt]>day_high)
{
day_high = High[cnt];
}
if (Low[cnt]<day_low)
{
day_low = Low[cnt];
}
cnt--;
}
H3 = ((yesterday_high - yesterday_low)* D3) + yesterday_close;
H4 = ((yesterday_high - yesterday_low)* D4) + yesterday_close;
L3 = yesterday_close - ((yesterday_high - yesterday_low)*(D3));
L4 = yesterday_close - ((yesterday_high - yesterday_low)*(D4));
L5 = yesterday_close - (H5 - yesterday_close);
H5 = (yesterday_high/yesterday_low)*yesterday_close;
Print ("H3: " + DoubleToStr(H3));
Print ("H4: " + DoubleToStr(H4));
Print ("H5: " + DoubleToStr(H5));
Print ("L3: " + DoubleToStr(L3));
Print ("L4: " + DoubleToStr(L4));
Print ("L5: " + DoubleToStr(L5));
