Any way to check for a new day?

There are my view to your problems:

1) I know how to have the indicator update every new bar but is there anyway to only have it update every new day?


init() {
Today=DayOfWeek();
}
bool IsNewDay() {

if(Today!=DayOfWeek()) {
Today=DayOfWeek();
return(true);
}
return(false);
}

2) Also is there any function in mql4 that gives you market open and close times? I can't see anything myself. MarketInfo() doesn't give you this information

Time[0]-Bar opening Time. Determiny the closing time is not so trivial.
