Quick questions

Where can I find a daily pre-market and post-market report for the Indian market?
On this page: TBTflow's pre-market brief (before 09:00 IST) and post-market brief (after the close) for NSE F&O, every trading day, free and without sign-in.
How is the post-market brief different from Gainers, losers & breadth and the tape read?
The post-market brief is the day on one page. Gainers, losers & breadth has the full lists for every F&O stock, and the tape read shows how the top 5 gainers and losers moved through the day.
Is this investment advice?
No. The briefs describe what moved and what is linked to it; they never say what to buy or sell.

These pages describe market activity. They are not investment advice and not a recommendation to buy or sell any security. TBTflow is not registered with SEBI.
