MultiCharts: Trading Software for Automated Trading and Backtesting

Example: time interval chart is 5 minutes

TimeInterval= 5 minutes
Start Time =2300

startTime + TimeInterval*15 = 2300 + 5*15(1 hours and 15 minutes) = 00: 15 minutes

turbofib,

you can not directly add minutes to HHMM times and expect the result to be correct. One way to accomplish what you have in mind could be to use
TimeToMinutes to convert your time to minutes, perform the summation, and convert the result back to a time using MinutesToTime.
