I was happy to find out that the usage of TimeCurrent() and TimeLocal() as well as the other time functions in Mt4 have been improved so that they work on a fictitous (tester) chart.

In the past it was a hassle to catch the time of the individual candles and retrieve the time stamp and then convert to the day of the week .. TimeDayOfWeek(Time[0]).. now that is all in the past.

I’m not sure which update of mt4 made this change as they never provide a changelog of improvements. They just let us find them as time goes by..
