I have been downloading and saving the historical 1 min data for stocks in F&O universe. I am also saving down the intraday data for futures on these stocks. Last few days, I have been facing issues of missing data on Futures side. There are total 188 stocks currently in F&O segment. But the futures data availability for last few days is as below: - 5th May: 141 Stocks - 8th May: 159 Stocks - 9th May: 148 Stocks
Any idea why is the data missing for so many stock futures ?
