Set Start Time for Chart Bars
You may want to set a start time for building chart bars, for example with a bar size of 1-hour MotiveWave by default will build the bar from 09:00 - 09:59, 10:00 - 10:59, and so on. This can be changed to line up with a specific time such as the US equity market open so your bars are built from 09:30 - 10:29 and so on. This can be configured per instrument in the edit instrument dialog under the Intraday Bars tab. It can also be found as a global setting in Configure > Preferences > Historical Data > General, under the Intraday Bar Build Method section.
