Direct answer: when daily forex candles update
Daily forex candles update when the chart starts a new daily “bar” (the next trading day on that chart). Until the daily bar closes, the candle for the current day can keep changing as price moves.
Because charts use a timezone and a platform-specific roll-over rule, the moment the candle switches to a new day can differ between brokers and between chart settings.
Explanation: what “daily candle update” means
A daily forex candle summarizes price for a fixed interval: one day according to the chart’s timeframe definition. That interval is typically set using:
- Timeframe selection: “Daily” means each candle covers one calendar day (24 hours) based on the chart timeframe.
- Timezone: the chart converts platform time into a timezone for candle boundaries.
- Daily roll-over time: the platform decides when the candle boundary occurs (for example, at 00:00 in the chosen timezone, or at another configured cutoff).
As a result:
- Closed daily candles represent completed daily bars and should not change after the bar has closed (for that platform and those settings).
- The latest daily candle is often “still forming,” so its open/high/low/close values can update continuously during the day.
If you switch timezone or use a different platform, the daily candles can realign because the cutoff moment changes.
Example checks you can do on any chart
You can verify the update behavior without relying on market-wide announcements:
- Compare two chart timezones (if your platform allows it). You should see the candle boundary and candle shapes shift when the timezone changes.
- Watch the current day’s daily candle near midnight in your selected chart timezone. If the candle persists through price movement, it is still forming; once it flips to a new candle, the prior one has effectively closed for your chart.
- Cross-check with the daily open time shown by your platform (some platforms display session or server time). The daily candle typically changes right after the platform’s daily cutoff.
Relevant limitations and uncertainty
Daily candle update times are not a single universal moment. They depend on:
- the chart’s timezone and the platform’s daily roll-over setting;
- the instrument feed and platform behavior (for example, some data sources may handle boundaries slightly differently);
- whether you are looking at the latest forming candle or a fully closed candle.
Because the latest candle can continue changing until its daily boundary, you should avoid assuming that the values you see at one moment will remain identical later the same day.
Limitations and what you should not infer
This explanation describes how daily candles generally update on charts. It does not provide real-time updates, guaranteed outcomes, or any trade signals. For any specific broker or instrument, the most reliable verification is to check your platform’s timezone and daily roll-over behavior on the chart.
