OHLC on WebNotes

Historical-candle values change after refresh (Kite)

Tue, 19 May 2026 00:00:00 +0000

Historical candle values changing after refresh on Zerodha Kite charts is a confusing but explainable behaviour. The OHLC values of past candles aren’t “frozen” forever; they can update due to corporate action adjustments, exchange data corrections, or feed reconciliation.

This article explains the underlying mechanisms and when each applies.

Corporate action adjustment

The most common reason. When a stock undergoes a split, bonus, dividend, or other corporate action, Kite charts (by default in adjusted mode) re-scale all historical candles to reflect the new capital structure.

OHLC differs daily vs hourly (Kite)

Tue, 19 May 2026 00:00:00 +0000

OHLC on Kite can show different values when switching between daily and hourly (or 5-min, 15-min, etc.) timeframes. The difference is structural: daily candles aggregate the entire session; hourly candles aggregate hour-by-hour with specific boundaries.

Daily candle composition

A daily candle aggregates the full trading session:

Open: first traded price of the session (typically 9:15 AM for equity).
High: highest traded price across the session.
Low: lowest traded price across the session.
Close: last traded price of the session (typically 3:30 PM).

Hourly candle composition

An hourly candle aggregates one hour, anchored to specific boundaries. For Indian equity:

OHLC differs on intraday charts (Kite)

Tue, 19 May 2026 00:00:00 +0000

OHLC on intraday timeframes (1-min, 5-min, 15-min, hourly) on Zerodha Kite shows different values because each timeframe aggregates ticks into candles of different durations. This is correct behaviour, but can confuse traders comparing across timeframes.

How aggregation works

A 5-min candle aggregates 5 minutes of ticks:

Open: first traded price in the 5-min window.
High: max price in the window.
Low: min price in the window.
Close: last traded price in the window.

A 1-min candle does the same for 1 minute. A 15-min for 15 minutes. The aggregation period defines the candle’s OHLC.

OHLC not matching NSE/BSE (Kite)

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.
