Every book's price for every bet — the green cell is the best price. Betting the best line is the easiest edge there is.
Real player & pitcher props from Bovada's full board, with de-vigged implied probabilities. Single-book markets — no consensus edge is claimed. Tap ＋ to build a parlay and see its fair value before you bet it anywhere.
Every Underdog Fantasy pick'em line for this sport, checked against the sportsbook consensus at the same number. Lines where the books say one side is 54%+ are profitable pick'em entries — the same math paid fantasy optimizers charge for.
When two books disagree enough, backing both sides locks in profit no matter who wins. Rare, and gone in minutes — act fast or not at all.
Middles — win both sides
Over at a low total + Under at a higher one. Land in the gap and both bets cash; miss and you only pay the hold.
Low hold — near-zero vig pairs
Two-sided bets with under 1% combined vig — the cheapest way to churn deposit bonuses and promos.
Where the smart (and big) money is. Whale trades from Kalshi's public tape, books quoting suspiciously far from the consensus (stale or informed lines), and the biggest moves since open.
Biggest bettors — Kalshi trade tape
Suspicious lines — books off the consensus
Steam — biggest moves since open
Reverse line movement — sharp vs public
The line moved one way while most of the money (Kalshi tape) sits on the other side — the classic signature of sharp action outweighing public volume.
The honest ledger: every +EV pick EdgeFinder's consensus flagged (≥4 books, ≥2% edge) is logged server-side the moment it appears and auto-graded against final scores at flat 1-unit stakes. No cherry-picking — this is what following the tool would actually have returned.

Checking…
Optional on this computer. Creating the first account locks profile sync and
Kalshi trading behind a sign-in — required before exposing the server beyond localhost
(HOST=0.0.0.0). Each account gets its own saved settings and tracked bets.
Kalshi account & auto-trading
Kalshi is a CFTC-regulated event exchange — its game markets appear above as another "book". Connect your own account (API key from kalshi.com → Account → API) to see your balance and let EdgeFinder place capped trades when the sportsbook consensus says a Kalshi price is wrong. Dry-run is on by default: trades are journaled, not sent, until you explicitly turn dry-run off.

Auto-trader
A contract pays $1 if it wins; buying at 45¢ risks 45¢ each. Edges above 25% are ignored as probable data errors. Exchange fees are not modeled — set min edge high enough to clear them (~1–2%).
Trade journal
Every auto-trader decision and manual order, newest first.
Dry-run performance
Every journaled trade graded against Kalshi's real settlement — the honest test of whether these edges make money before you risk a cent.

How the edge is computed
- Every book's odds are collected per market and de-vigged four ways (multiplicative, additive, power, Shin) — the conservative "worst-case" edge survives all of them.
- Books are averaged into a consensus fair probability — sharp books (Pinnacle) weighted 3×, and optionally by market width (tighter vig = sharper price).
- Prices beating the fair probability are +EV. Confidence reflects how many books agree.
