Split adjustment data

punitkandoi
Hi,

I was quering data from MBAPL using kite historical data and seeing its not split adjusted even after 10 days.
But in kite i see its adjusted.

So can you please explain clearly when data is adjusted via paid historical data? since multiple thread but didn't saw any actual explanation on same.

Why zerodha data and historical eod data is not same? so zerodha doesn't use paid historical data?

    Hi @punitkandoi, the historical data for MBAPL is already updated to reflect the corporate action adjustments. Could you please retry fetching the historical data using the Historical Data endpoint API and let us know if you continue to observe any discrepancies?
  • punitkandoi
    Thank you @salim_chisty but few questions:
    1. How much time it takes for it to address corporate action adjustment?
    2. How does api knows there is corporate action adjustment and need to download historical data to make sure we are not downloading complete data everyday?
    3. Also on a topic i am very confused on stock moving to RE and multiple symbol in data downloading and breaking chart. Any insight on how to track their data cleanly like zerodha kite?

    @punitkandoi
    1. Corporate action adjustments are completed as part of the beginning-of-day process on the ex-date, before the market opens.
    2. Corporate actions are generally updated before market opening on the ex-date. Demergers are an exception and are updated once we receive the applicable Cost of Acquisition (COA) file. You can verify the adjusted closing price against the exchange bhav copy and the closing price returned through the Historical Data API.
    3. We do not perform historical chart-price adjustments for Rights Entitlement (RE) instruments. Could you please elaborate on your concern?
  • punitkandoi
    yes regarding RE do you adjust that and how BE scripts are updated. since i saw 2 instrument one with normal and one with BE
