Why do stock charts differ across platforms for the same timeframe?
Chart differences across trading platforms are common and stem from how each platform processes and plots tick data—the raw data of individual trades executed on the exchange. These small differences can affect chart precision, especially for intraday candles.
Why does this happen?
- Tick Data Processing: Stock exchanges process hundreds of ticks per second. However, charting platforms typically display one tick per second
- Chart Construction: Exchanges provide daily OHLC data only. For intraday intervals like 1-minute or hourly, platforms build their own candles from the tick stream they receive
- Data Selection: Different platforms receive and process ticks at slightly different times, leading to discrepancies in how candles are formed
FYERS Tick Speed Advantage
FYERS processes and updates tick data every 300 milliseconds, one of the fastest among retail brokerages. This ultra-low-latency feed enables:
- More accurate candle construction
- Faster price updates
- A clearer and more responsive market view
Minor chart differences are expected but rarely affect retail trading decisions. Focus on trend consistency rather than absolute candle precision.
What if I need precise tick data?
- NSE provides Tick-by-Tick (TBT) data via authorized vendors
- Co-location access allows high-frequency trading systems to operate directly at the exchange for minimal latency
- These are mostly used by institutional or algo traders
What if...
| Scenario | Outcome |
|---|
| My 1-minute candle on FYERS differs from another platform | Caused by slight variation in tick selection and processing speed. |
| I need absolute precision for high-frequency trading | Consider TBT data or co-location solutions. |
| I’m a retail trader using standard charts | Minor differences have negligible impact on trade decisions. |
