Dhan’s current API rate limit is too conservative for historical data usage. Without a bulk historical endpoint, developers must fetch candles symbol by symbol. Pulling 30 days of data for 2,700 equity symbols took 9 minutes, which is inefficient even for EOD analysis. What is the recommended way to fetch historical data for all equity symbols at scale?
Can Dhan provide bulk historical data for popular ranges like 7, 14, 21, and 50 days for all equity symbols in a single request?
This would drastically reduce load, improve performance, and make large-scale scanning practical.
