Zerodha OHLC intraday timeframe

OHLC differs on intraday charts (Kite)

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

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.

Why values differ across timeframes

The 5-min high of a window equals the max of 5 consecutive 1-min highs. The 15-min high of a window equals the max of 3 consecutive 5-min highs (or 15 consecutive 1-min highs).

Wider timeframes have wider highs and wider lows. The numbers are mathematically related (aggregations of the same underlying tick data) but not the same numbers in each cell.

Common confusion

User looks at 5-min chart and sees High = 1,050. Switches to 1-min and looks at the same window. Sees five 1-min candles with highs of 1,045, 1,048, 1,050, 1,046, 1,043. The 5-min high (1,050) appears in only one of the 1-min candles.

This is correct: the 5-min high is the max across the 5 minutes.

When values would differ unexpectedly

If 5-min and 1-min OHLC for the same window don’t reconcile mathematically (e.g., 5-min high not equal to max of 1-min highs):

  • Data refresh in progress.
  • Continuous chart back-adjustment.
  • Tick gap or feed issue.

Verify by waiting and refreshing; if persistent, raise ticket.
