Eudora Session Clock

The trading day on one dial: sessions, overlaps and the countdown to the close of the candle.

Session Clock answers at a glance which sessions are open right now, how long until the next one opens, and how much time is left on the current candle. Free, and part of the Eudora Instruments series.

What the panel shows

• Dial: 24 hours in GMT, one arc each for Sydney, Tokyo, London and New York. An open session is bright with a soft glow; the hand marks the current time.
• Candle countdown: the time left before the current candle closes, with a ring that fills as the candle progresses. When the market is closed it shows the time to the next trading session of the symbol.
• Legend: one line per session with its hours and "open, closes in 2h 14m" or "opens in 5h 02m".
• Spread: the current spread against its average since the indicator was loaded.
• Day range: today's range as a percentage of the 14-day average.
• GMT and server time, side by side.

Daylight saving time, handled for you

London follows the European rule, New York the United States rule and Sydney the Australian rule, each on its own dates. The weeks of March, October and November in which the three are out of step are shown correctly.

Built with care

• Animated panel drawn on a canvas: the arcs draw themselves in and the hand moves with the clock.
• A button folds the panel into a slim bar with the open sessions and the candle countdown. Drag it anywhere on the chart; it remembers its place chart by chart.
• Light on the terminal: a few frames per second at rest.

Inputs

• Position, size and accent color of the panel; start collapsed.
• Opening hour in GMT of each session (northern winter: 21, 0, 8, 13).
• Automatic daylight saving time, on by default.

Works on any symbol and timeframe.
