OHLC ForgeDaily Bars for Crypto Perpetuals in Your Time Zone
Most cryptocurrency exchanges close their daily candles at 00:00 UTC. This is an international standard, but it creates a real problem for systematic traders who need to update their data and place orders every day.
Daily bar closes at midnight UTC
For most traders, this means staying up late at night or waking up in the middle of the night to update data and place orders.
Daily bar closes at your chosen time
Update your data, place your orders, and go to bed at a reasonable hour. Same trading system, same logic, better lifestyle.
See how the default 00:00 UTC close time affects traders in different locations, and how OHLC Forge solves this problem:

Note: Times shown as "winter / summer" for locations with Daylight Saving Time. The second time in each cell applies during DST (summer time).
The time zone settings in OHLC Forge (e.g., UTC+3) are fixed UTC offsets, not dynamic time zones that adjust for Daylight Saving Time (DST).
This means that if you select UTC+3 (bar closes at 21:00 UTC):
The daily bar always closes at exactly the same moment in UTC. However, your local clock time for that moment will shift by 1 hour when your region switches between standard time and daylight saving time.
Plan your daily routine accordingly — your data update time will be one hour later (in local time) during summer months in DST regions.
Results should be very similar, though minor differences are expected. The underlying price movements are the same — you're just slicing the 24-hour periods at different points. If your backtest results change significantly when shifting the daily bar close time by a few hours, this is a strong indicator that your system may be overfitted (curve-fitted) to specific data artefacts rather than capturing genuine market behaviour.
UTC (Coordinated Universal Time) is the international standard for timekeeping. It's neutral and doesn't favour any particular region. However, "neutral" for the world often means "inconvenient" for individual traders who need to act on the data every day.
Yes! OHLC Forge creates separate data files for each exchange. You can run the tool multiple times with different settings and save to different folders if you wish to compare or use multiple time zone versions.
Correct — crypto markets never close. Your daily bars will be continuous, including Saturday and Sunday. The time zone setting simply determines when each 24-hour period begins and ends.
Exchange data only provides UTC+0 daily bars (closing at midnight UTC). OHLC Forge downloads hourly data and reconstructs daily bars according to your chosen time zone. This is the only way to obtain custom time zone daily data for crypto.
