Yesterday's i.e. 16/01/2020 Bank Nifty API O = 31832.95 whereas O = 31810.95 on charts (pro.upstox.com). Similarly, H = 31955.30 on API and 31953.60 on charts for a 5 minute time frame. This errornous data on API leads to loss for my strategy.
What is the reason for this? How should one take care / get correct data?
Please reply asap
