Why does a trade appear on different dates in Local and Broker time?

By Chart Reporter Reviewed 2 min read

The short answer

One instant can belong to different calendar days in different timezones. Chart Reporter's Local and Broker modes change the boundaries of the selected date window. A trade moving between daily groups after a timezone switch does not, by itself, indicate a changed execution timestamp.

Separate an instant from its calendar label

A timestamp identifies when an event occurred. A timezone determines which local clock and calendar date describe that instant. Around midnight, two legitimate views of the same event can show different dates. Daily journal totals inherit that choice.

Suppose an exit is late on Monday in one timezone and early Tuesday in another. A Monday-only filter can include it in one view and exclude it in the other. The trade did not move in time; the selected calendar interval refers to a different range of instants.

Make the comparison reproducible

Before comparing two daily reports, record the account, selected timezone, date window and timestamp basis. Check whether the question concerns entries, exits or an explicit session. These are separate decisions, and matching the displayed date labels alone is not enough.

Chart Reporter interprets inclusive calendar selections using the start of the first day and the start of the day after the last date in the chosen timezone. Daylight-saving changes can affect those boundaries. When diagnosing broker-time differences, select a single hub instead of combining accounts whose broker timezone settings differ.

Use the same convention in notes and reviews

If your trading session crosses midnight, name the session and its actual window rather than relying only on a date label. Include the timezone in a shared review or screenshot annotation. This reduces ambiguity when returning to the same trades from another device or location.

When a total changes after switching modes, compare the records near the boundaries first. That is more informative than assuming a missing import or a duplicated trade. Retain the original execution times and explain the grouping convention. A clear timezone policy makes subsequent weekly and monthly comparisons easier to reproduce without changing the underlying history.
