Steam Moves - Following Sharp Money vs Finding It Yourself

[SharpEddie47]

A steam move: a rapid, simultaneous line movement across multiple sportsbooks, usually triggered by significant action at one or more reference books.

In American sports betting: Pinnacle and Circa are widely treated as reference books. Most smaller operators don't have the risk management infrastructure to independently price every market, so they set their lines using these books as a baseline and adjust from there.

When a large bet hits Pinnacle and moves their number significantly: other books that reference Pinnacle's line follow within minutes, sometimes seconds.

A steam-chasing service: software that monitors line movement across dozens of books simultaneously, detects when multiple books move in the same direction within a short window, and alerts subscribers that a steam move is occurring.

The promise: someone with significant capital and presumably significant information just moved this market. Follow them.

The question this thread is built around: by the time you receive that alert and act on it, what's actually left.

The exchange's relationship to steam is specific and worth establishing first.

The exchange price often is the reference point, not just for other exchanges but for fixed-odds books that use exchange data as one input into their own pricing.

A significant move on the exchange, driven by genuine money taking a position: this can itself be the origin of what a steam-detection service downstream identifies as "steam" at fixed-odds books.

When a book takes an unusually large bet relative to their normal limits on a specific market: the standard response is to "circle" the game, temporarily suspending it, and re-post a new number once they've reassessed.

A circled game reappearing at a different price: one of the clearest signals available that something significant just happened. It's also one of the slowest to reappear, because the suspension itself takes time.

paid for a steam alert service for about four months during a bad period...

the pitch was specific: professional syndicates move millions, when they move the market follows, you get alerted within seconds and can get on before the soft books catch up...

what it actually felt like: notifications arriving on my phone, each one saying essentially "something is happening, act now"...

placed bets off these alerts constantly...

the specific appeal wasn't really about the edge...

it was that someone else, somewhere, with more money and presumably more information than me, had already decided...

i wasn't analyzing anything... i was reacting to a notification that told me someone smarter had already analyzed it...

the responsibility wasn't mine... the conviction wasn't mine...

i was borrowing both, in real time, for a subscription fee...

 

[FadeThePublic]

Conor's framing of "borrowed conviction" is precisely the psychological mechanism, and it connects directly to the fade-the-public methodology in a way worth examining.

Fading the public: I form my own view, independent of what the crowd is doing, often specifically because of what the crowd is doing.

Following steam: I form no view of my own, and instead adopt whatever view the detected movement implies someone else has.

These can point the same direction. Steam often moves against the side the public is heavily backing, because that's exactly the situation where a sharp position creates a meaningful price gap to exploit.

But they're not the same activity. One requires you to have a model of public behavior and a reason to disagree with it. The other requires nothing except a fast notification and a willingness to act on it.

The first is analysis. The second is, as Conor describes it, a form of following.
