Hello, As per the new update historical_daily_data now takes security_id as a parameter instead of the symbol name. This is not mentioned in the example given on Historical Data - DhanHQ Ver 1.0 / API Document
Please mention the same to avoid confusion for new learners. Additionally, it should also be mentioned in the documentation that this data is only accessible by subscribing to the Data APIs with 500+GST Payment.
Though, it is all helpful. Thank you.
