How daily market data works

Last updated September 14, 2026

CRTLAB's market data updates every day. Each morning, yesterday's full session is added to every market, so you can backtest yesterday's market today, free. Data is currently through Friday, 6 November 2026.

When new data arrives

  • The update runs automatically every day at about 07:00 UTC. Nobody presses a button.
  • Futures, forex, metals, oil and indices gain the previous trading day's full session, up to its close.
  • Stocks and ETFs gain the previous regular session (to the 16:00 New York close).
  • Crypto trades every day, so it is brought right up to the morning update, weekends included.
  • DAX (GER40) data is published later by the exchange, so it can arrive one update after the others.

Every update is checked before it goes live

Each market is checked before anyone sees it: the older candles must be unchanged, there must be no gaps, flat stretches or spikes, the bar count must be right and the last day must be complete. A market that fails a check simply keeps its previous data, and the update tries again the next morning. You never get a half-built day.

What updates with it

  • Candles on every timeframe, 1 minute to monthly, on all 38 markets.
  • Real volume, volume profile and the footprint.
  • The economic calendar and news tags on the chart and in the session calendar.
  • The session calendar itself: the newest day shows as the last day, and the next one is marked as coming next.

There is nothing to download or refresh. Open a new session and the new day is there.

Free every day

Every account gets 2,000 free candles of replay every day, with every feature, no card. They reset at 00:00 UTC. Unlimited replay removes the limit.

Why it matters

Practising on the session that just happened is the closest thing to live trading without risk. You always have a fresh day to replay, you never run out of sessions, and you can review yesterday's market the morning after it closed. Open the chart or read how to backtest yesterday's market.
