Hello,

On 14th June 2017, BIOCON (NSE) price in historical data as well as live feed on zerodha website shows closing of "Rs. 516" and opening on 15th June 2017 shows a drop of Rs. 170.

There are many other stocks having such discrepancies. Can you please run a query for all stocks and fix these issues with historical data. My algo's tend to screw up as incorrect technical value for technical indicators are being calculated.

    Yes, there was corporate action of Bonus issue 2:1 on 15/06/2017. So, the historical data is adjusted accordingly.
    Also, close for BIOCON(2911489) is showing adjusted close value of 169.95 not 516. You need to re-check the same at your end.2017-06-14 00:00:00+05:30,172.35,172.35,169,169.95,3813207

    Hi Rakesh! Thanks for the prompt reply.

    On your live feed i.e on kite.zerodha.com charts, this change is not seen and the prices are shown as Rs. 516. The charts and historical data don't share the same database?
