A screener view ranking F&O contracts by the largest decrease in open interest, highlighting where existing positions are being closed out fastest.
OI losers is the mirror of OI gainers — a screener view that ranks futures and options contracts by the largest fall in open interest over a chosen period. It surfaces the largest negative change in OI across the F&O universe, showing where existing positions are being closed out fastest, without on its own telling you whether it’s longs or shorts doing the closing.
As with OI gainers, traders read the OI losers list alongside price direction to classify the move: a contract topping the list with price falling points to long unwinding, while the same OI decline with price rising points to short covering. This combination is particularly useful for spotting potential short-squeeze candidates — stocks with a sharp OI decline and a strong price bounce are often where trapped short sellers are being forced to buy back in a hurry.
A well-known distortion in the OI losers list shows up in the days leading into monthly or weekly expiry, when open interest in the current-month contract falls across the board simply because traders are rolling positions into the next expiry rather than exiting the market. This expiry-driven decline can dominate the OI losers list and needs to be filtered out, or at least recognised, before assuming a broad wave of unwinding or short covering is underway.
Because a large OI loser can also result from just one or two big positions being closed in an otherwise thin contract, it’s worth checking the absolute lot count alongside the percentage fall, and cross-referencing with volume, before treating a name on the OI losers list as a reliable signal on an F&O market screener.
