I want to 1 hour candle once it is closed. lets say i want 09:15am , 10:15am and so on. This candle will complete on the next minute.
09:15 candle will get complete only when 09:16AM. 10:15AM candle complete only when 10:16AM 11:15AM candle complete only when 11:16AM 12:15AM candle complete only when 12:16AM 01:15PM candle complete only when 01:16 PM 02:15PM candle complete only when 02:16 PM 03:15PM candle complete only when 03:16 PM
so i want this 1 hour candle data. Whether this should be fetched from historical api as like below.
or can i monitor every tick and calculate the ohlc by myself in proram.. i believe this approach will be error prone. Since i might not get all the ticks from broker.. and this will be overhead my system.
if i relay on historical api, will i get 1 hour candle data of 10:15AM at 10:16AM ? or at latest when will i receive 10:15AM closed one hour candle ?
@Sravanthi_bh - I feel tick data is not ideal due to below reasons. Option 1 : Using tick data Why NOT ideal: 1) Tick data is not guaranteed to be complete. Brokers like Zerodha send only relevant price updates. 2) I won’t receive all trades, especially for illiquid options or deep OTM strikes. 3) Overhead: I will need to manage candle state, time alignment, rollovers, and edge conditions (like no tick near 10:15).
Option 2 : Use Zerodha’s historical_data() API with interval="60minute" Why Ideal 1) Zerodha's API already provides 1-hour aggregated OHLC data. 2) Candles are time-aligned to 15th minute, e.g.: 3) Candle labeled 10:15 means: 09:15 → 10:15 interval. That candle will typically be available by 10:16:00 – 10:17:00, depending on their backend batch process latency
Here I have one question how quick or how much delay i will observe when i call historical api for the 1 hour candle which just got closed ? For example now time is 11:16AM i was looking for 10:15AM to 11:15AM 1 hour time candle from historical API. Approximately when will i receive this data via historical api ?
