Day Counter
Same as new bar test, but using date.
static datetime currentDay=0; datetime previousDay = currentDay; currentDay = date(); bool isNewDay = currentDay != previousDay;

For a new bar test, Bars is unreliable (a refresh/reconnect can change number of bars on chart,) volume is unreliable (miss ticks,) Price is unreliable (duplicate prices and The == operand. - MQL4 programming forum.) Always use time.
I disagree with making a new bar function, because it can only be called once per tick. A variable can be tested multiple times.

- You could also use D1 timeframe, but then you have to deal with 4066/synchronization issue. On MT4: Unless the current chart is that
specific symbols/TFs referenced, you
must handle 4066/4073
errors before accessing candle/indicator values.

On MT5: Unless the chart is that specific pair/TF, you must Synchronize the terminal Data from the Server.

Thank you, but mt5 please.
Merry Christmas everyone!
I have been trying to figure out how to code when a day has passed, add one to the candle counter then determine if trading is allowed for that day. Any help will be greatly appreciated. A comment function for the day counter may also be helpful.
A new day can be defined in two ways. In both methods, you need to declare a variable at the global program level (in a simple way: you need to declare a variable in the "header")
Method 1: compare the current "Day number of the year" with the stored value
***
Method 2: compare the opening time of the daily bar (PERIUOD_D1) with the saved value
***

Thank you. Let me try it

Is it possible to define a weekend this way?
#define _secondsInADay 86400 int _currentDay = int(your time value here/_secondsInADay); int _currentDayOfWeek = (_currentDay+4)%7; bool _weekend = (_currentDayOfWeek==0 || _currentDayOfWeek==6);
