Zerodha OHLC NSE BSE reconciliation

OHLC not matching NSE/BSE (Kite)

From WebNotes, a public knowledge base. Last updated . Reading time ~2 min.

OHLC values on Zerodha Kite can sometimes differ slightly from the OHLC published by NSE or BSE. The differences are usually small (paise to a few rupees) and stem from data-feed timing, adjustment conventions, or aggregation methodology.

Common reasons for mismatch

Adjusted vs unadjusted

Kite default is adjusted prices (post-corporate-action scaling). NSE / BSE published values are typically unadjusted (raw historical data). After a stock split, Kite’s adjusted high differs from the exchange’s published unadjusted high.

Switch Kite to unadjusted mode to compare against exchange raw data.

Pre-open and post-close

NSE publishes both regular-session OHLC and including-pre-open OHLC. Kite’s daily candle typically uses regular-session-only or close-of-day depending on source convention.

Time-of-day boundary

Kite’s daily candle may close at 3:30 PM exactly; NSE may include any post-close auction transactions. Small differences possible.

Tick precision

Kite’s aggregation uses Zerodha’s data feed which is normalised. NSE publishes raw tick precision. For thinly-traded stocks with low precision, rounding can cause differences.

Exchange data corrections

NSE / BSE occasionally issue erroneous-trade corrections; Kite’s data feed may reflect these with a lag.

When the difference is material

If the difference is in rupees (not paise), and not explained by adjustment / split / dividend:

  • Refresh Kite chart.
  • Compare against exchange’s authoritative end-of-day data.
  • If persistent, raise ticket with Zerodha support.

For most users, paise-level differences are not material.
