Most flow tools tell you what moved.
This one tells you what was being bought.
FlowDesk scores every options print on the tape, shows you the working behind each score, and publishes how those calls have actually done — wins and losses alike.

How a score gets made
Three steps, fully transparent. The formulas are public — argue with any weighting you disagree with.
- 1
Read the chain
Every contract on the options chain, split into calls and puts, by what traded today and by what was already on the books.
- 2
Score the flow
Two components — volume bias and open-interest bias — blended 62/38 into one composite between -100 and +100, each shown separately so you can disagree with either.
- 3
Mark the result
Published calls get resolved against real forward prices and added to the track record, wins and losses alike.
We publish the losses too
Every prediction is resolved and counted, including the ones that went the wrong way, and the page shows a rolling window alongside the all-time figure so a good month cannot stand in for the record. You do not need an account to read it.
The fact that they publish the losses alongside the wins is what made me trust the tool. Every other flow scanner shows you the wins and buries the rest. FlowDesk shows you the full record and lets you judge.
