Two charts of the same stock and timeframe can look slightly different even on the same platform. The reason is the number of price points each chart is built from.
Live data vs stored data
- A live chart is drawn from real-time ticks — as the market moves, the streaming feed sends several price points for each candle.
- A newly opened chart is drawn from stored data points on the data server, which may hold only one price point for a candle in the same timeframe.
Because the live chart is built from more price points per candle than the stored one, the candles can look different — even though it's the same stock and the same timeframe.
What this means for you
- It's not an error — the two charts are simply built from different amounts of data.
- The stored data is the settled, official record; a live chart reconciles to it once its candles settle.
