For people already doing this
You know what an arb is. Here's what's different.
If you're running a subscription odds finder, you already know its failure modes: you're late to every line, everyone's racing the same shared feed, and the tool has no idea what you actually did with your money. CherryHouse is built around fixing exactly those things — scraping on your own machine, in the markets you hand-picked, with the bookkeeping baked in.
Latency
The usual setupA shared server scrapes the books, then fans the same feed out to every subscriber. You act on a line after it has been through someone else's queue — and after everyone else got it.
CherryHouseThe Chrome extension scrapes on your own machine, from the sportsbook tabs you already have open. There's no relay between the book's page and your screen, so you're reading the line at the moment the book renders it to you. Lock a bet in and its legs get refreshed first, so the odds you're about to place on stay the freshest thing on the page.
What gets scraped
The usual setupA fixed universe of leagues and markets, chosen by the vendor. Everyone hunting the same pool means the obvious arbs are gone before they load.
CherryHouseThe Custom League Builder lets you walk each book's live catalog and hand-select sports, leagues, competitions, and individual market subsections. Deep props and quiet leagues included — your market universe, and nobody else's.
Books covered
The usual setupDozens or hundreds of books you've never signed up for, so the 'arb' is between two sportsbooks you can't actually bet at.
CherryHouseLive scraping across six Ontario books you actually hold accounts at — FanDuel, DraftKings, BetRivers, Caesars, theScore, and Pinnacle — with Polymarket wired in on demand. Pinnacle's sharp lines double as a reference for spotting when the soft books are mispriced.
Market matching
The usual setupFuzzy string matching across books, which is how you end up staking both sides of two different markets and calling it an arb.
CherryHouseCurated section bindings you author yourself, plus veto invariants for the classic traps: three-way moneylines, combo labels, team totals mistaken for match totals. If it can't prove two legs are the same market, it won't pair them.
Bets on demand
The usual setupA passive list you refresh and hope something lands on. If nothing's there right now, you wait.
CherryHouseThe Cherry Picker takes a request — 'I'm holding a $100 bonus bet on FanDuel, find me a hedge' — and a scrape worker pulls the books on demand, sizes the legs, and hands back ready-to-place bet cards. You ask for a bet instead of scanning for one.
Bookkeeping
The usual setupA finder that forgets the bet the moment you place it. Your actual P/L lives in a spreadsheet you stopped updating in March.
CherryHouseEvery bet you log lands in an append-only ledger, per account and per book. Cash vs. bonus stake tracked separately, settlement and payout recorded, balances always derived from the ledger rather than typed in. Multi-currency accounts convert to CAD correctly, and open positions whose games have probably finished get flagged so you never forget to settle one.
Promo conversion
The usual setupTreated as an afterthought, if it's there at all — most finders only look for straight two-way arbs.
CherryHouseThe Cherry Maximizer is built around promos: bonus bets, profit boosts, and insurance each get their own stake maths, and analytics tell you how much bonus you've burnt and what conversion rate you're actually achieving per book. A live promo catalog scrapes the public offers each book is running, so you can see what's on the table before you chase it.
What it isn't
Worth knowing before you switch, so nothing here surprises you later.
Not a bet placer
CherryHouse is read-only by design. It never places, fills, or confirms a bet, and never sends synthetic input to a sportsbook. You click every button yourself — which is also why it never needs your book credentials.
Not a global feed
It covers the books you personally hold accounts at and keep open, focused on the Ontario market. If you want a thousand books you've never signed up for, this isn't that.
Not set-and-forget
You author your own section bindings in the League Builder. That's the work that buys you markets nobody else is watching — but it is work, up front, before the edge shows up.
