This is an indicator that can display Japan time on the chart without discomfort. You can hide MT4/MT5 time and only display Japan time for trading. The design is also the same as the original, so it doesn't get in the way (feeling). Of course, daylight saving time and winter time are accurately reflected from the past to the present. In addition, it supports integer display and color coding and price range display of the three major market periods. Also, I tried to make it possible to fine-tune the timeline zoom and measure time difference and price range with raw crosshairs.

Using a subwindow just to display Japanese time is a waste of space. It would be better to rewrite the original display time, but it seems difficult at the indicator level. You can hide the date and show only the time, or you can show 5 minutes or less on a 1-hour scale.
