Why do stock charts differ across platforms?
Chart differences across trading platforms are common and stem from how each platform processes and plots tick data—the raw stream of individual trades from the exchange. These differences can affect chart
precision, especially for intraday candles.
Why this happens?
- Tick data processing: Exchanges can see hundreds of ticks per second; charting systems often sample/aggregate (e.g., one tick/second) for plotting.
- Chart construction: Exchanges provide daily OHLC; for intraday (1-minute, hourly), platforms build candles from the live tick stream they receive.
- Data selection & latency: Platforms receive/process ticks at slightly different times, leading to small discrepancies in how candles are formed.
FYERS tick speed advantage
FYERS processes and updates tick data every 300 milliseconds. This 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-by-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 near the exchange for minimal latency.
- These solutions are typically used by institutional or algorithmic traders.
What if…
| Scenario | Outcome |
|---|
| My 1-minute candle on FYERS differs from another platform | Likely due to minor differences in tick selection and processing latency. |
| I need absolute precision for HFT | Consider TBT data or co-location solutions from authorized providers. |
| I’m a retail trader using standard charts | Small chart differences generally have negligible impact on trading decisions. |
