What is Market Hours?
Market Hours separates the London, New York, Sydney, and Tokyo sessions on a chart. The source colors are green for London, red for New York, blue for Sydney, and yellow for Tokyo.
Each session start and end can be changed from the Inputs dialog, making the display useful when broker time or a preferred session definition differs from the defaults.
How to use Market Hours
Apply Market Hours to an MT4 chart and use the colored lines to identify which session boundary is near the current candles.
Set the start and end time inputs for each session to match the broker clock, then keep the chart scale compact enough to see the session sequence.
Where it helps
Separates the London, New York, Sydney, and Tokyo time blocks in one view.
Makes the session boundaries easy to distinguish without extra labels.
Supports custom start and end times for different broker schedules.
