Trade the session on data, not noise

OptionsIndia.trade publishes live analysis of NIFTY and SENSEX index options and the NSE F&O stock universe, built from tick-by-tick exchange data and a rolling year of one-minute history. Everything is free to use and needs no sign-up.

The OI change page shows strike by strike where option writers are building and unwinding positions, which is where intraday support and resistance usually forms. The index options page charts individual strikes tick by tick with their own support and resistance levels and an estimate of which strike gains most from the next index move. The market edge page goes a step further and weighs that open interest by gamma — the hedging flow it actually generates. Its main signal is writer rotation: option writers buy back the side they are short and write the other one ahead of a turn, so the rotation shows up before the move does. It also shows the move the at-the-money straddle is pricing in and the strike the chain is pulling towards. Every rate on it carries the number of recorded sessions it was measured on.

For stocks, the bullish scanner scores every F&O name out of seven on VWAP, opening-range breakout, volume and relative strength; support bounces flags stocks testing levels buyers defended for months; and holding up best finds stocks falling less than their own history predicts when the index drops.

New to this? The guides explain how to read each page and where the numbers mislead. Every calculation is documented on the method page, including what the numbers do not tell you. This is measurement, not advice.
