Best AI for Analyze options flow and unusual activity
Track institutional options activity in real time — large block trades, multi-exchange sweeps, dark pool prints, and unusual volume vs. open interest — to spot smart money positioning before it shows in price.
Unusual Whales
Unusual Whales is the category leader for options flow because it was built ground-up for retail traders to track institutional options activity — huge block trades, unusual volume relative to open interest, sweeps across multiple exchanges, and the dark pool prints that often precede them. The chat-style flow feed shows every trade above configurable size thresholds in real time with contract details and an 'opening vs. closing' inference. Also publishes congressional trading disclosures (the data feature that put them on the map) and political-trader leaderboards. Premium is $48/month — meaningfully cheaper than the $200+/month flow platforms used by professional desks.

Before vs. after using this prompt
Trader sees NVDA pop 3% in an hour and wonders 'is this real flow or just retail?' They check Twitter, see screenshots from random accounts claiming 'massive call sweeps' but can't verify. By the time they decide, NVDA is up another 2% or has already faded.
Same trader opens Unusual Whales, filters for NVDA flow in the last 60 minutes, sees three sweeps totaling $4.2M in premium on calls expiring this Friday, marked as opening positions, with one block trade at the same strike from a dark pool print 20 minutes earlier. Conviction signal is high — this is institutional positioning, not retail noise. Decision time: 90 seconds.

Use Cheddar Flow if you prefer scanning dashboards; use Unusual Whales if you prefer a chronological flow feed with alpha data on the side.
Open Cheddar FlowFrequently asked
Does following options flow actually work, or is it gambling on what big money is doing?
It works as one signal among many, not as a standalone strategy. Following every sweep blindly is a losing game — many institutional trades are hedges, not directional bets. The edge comes from combining flow with technical setup, fundamental catalyst, and your own thesis. Flow that aligns with all three is high-conviction; flow alone is noise.
What's a 'sweep' and why does it matter more than a regular block trade?
A sweep is an options order split across multiple exchanges to fill quickly at any price — the trader is willing to pay up to get the position on now, suggesting time-sensitive conviction. A regular block trade can be a patient buyer or a hedge. Sweeps on calls expiring in days, especially during low-volume hours, are the highest-conviction flow signal.
Can I get this data for free anywhere?
Partial — most brokers show top options volume gainers and put/call ratios for free. What you can't get free is the institutional-grade detail: real-time sweep vs. block classification, dark pool integration, congressional disclosures, and configurable size thresholds. Free data is enough to know 'something happened'; paid flow tools tell you what.
