How this screen works

A Short Buildup happens when a stock's price falls and its open interest rises. Falling price with rising OI means new short positions are being created — traders are betting on further downside and carrying those shorts overnight. It is the clearest bearish footprint in F&O data.

This screen lists every F&O stock classified as Short Buildup in the latest NSE session, ranked by the size of the open-interest change.

Strota classifies each F&O stock from the NSE F&O bhavcopy. Short Buildup = price down + OI up.

Stocks are ranked by absolute OI change percentage — the largest fresh short positioning sits at the top.

Short Buildup describes bearish positioning; it is not a recommendation to sell. Heavy short buildup can also set up a short-covering bounce later.

FAQ

What does Short Buildup mean?
Short Buildup means a stock's price fell while its futures open interest rose in the same session. New open interest on a down move signals fresh short positions being added — a bearish signal.

How is the Short Buildup list calculated?
Strota classifies every F&O stock from the NSE F&O bhavcopy by comparing the day's price change with the day's open-interest change. Price down + OI up is tagged Short Buildup, then ranked by OI change.

Is heavy short buildup always bearish?
It reflects bearish positioning, but a stock with very heavy short buildup can later rally sharply if those shorts are forced to cover. It is positioning information, not buy/sell advice.

How often does the list update?
Every trading session once the NSE F&O bhavcopy is processed (around 6:30 PM IST), and live during market hours when a broker feed is connected.
