THE PROBLEM
You own stocks. You should know when massive bets land on them.
You're holding, blind
Institutions place large, time-limited options bets on the very stocks you own - often right before the move. Miss them and you ride it out with no idea what's coming.
Watching it is a full-time job
The only way to catch these bets yourself is to babysit a flow terminal all day. It works - if staring at a screen is your job. For everyone else it's one more tab you feel guilty about.
You hear it last
By the time the move hits the news, the position was built hours ago and the edge is gone. It was your stock - and you found out from a headline.
OPTIONS FLOW ALERTS
Everything the tape is telling you.
Unusual options in one email.
Your options flow alerts arrive as the prints land, so nothing depends on you having a tab open. The underlying options flow stays browsable whenever you want the wider picture.
Unusual activity
Volume far above open interest, real premium behind it - the print institutions leave.
Per-ticker filters
Your tickers, your thresholds: Vol/OI, premium, IV, DTE, calls or puts. No caps.
Unusual options flow
Sweeps, blocks and multi-leg prints - not just the household names.
IV & OI context
IV rank and open-interest changes on every row, so a spike reads in seconds.
Sector aggregates
Where the premium is concentrating today - by sector, by symbol, by side.
REST API, included
Every signal is queryable programmatically. 2,000 requests/day in the base plan.
FROM ZERO TO ALERTED
Two minutes to set up. Then unusual bets on your stocks find you.
