Questions sharp bettors ask.
What is Dynatyze Betting?
Dynatyze Betting is a sports betting research suite for the NBA, MLB, the NFL, and the World Cup. It compares prices across 51 sportsbooks and DFS pick'em apps, prices every player prop against a de-vigged fair line, tracks sharp money and arbitrage windows, and grades every published pick against the closing line — in public. It is not a sportsbook: you can't place a bet on Dynatyze, only find the best one.
What is a betting edge?
An edge is the gap between what a bet should cost and what a book is charging. Dynatyze strips the vig from the sharpest market consensus to get a fair line, then compares it to the best available price across every book. When the best price implies a lower win probability than the fair line says the bet actually carries, that difference is positive expected value — the edge score printed on every card.
What does removing the vig (de-vigging) mean?
Sportsbooks bake a commission into both sides of every market, so the implied probabilities of a two-way market add up to more than 100%. De-vigging removes that margin to recover the market's true probability for each outcome: a -110/-110 total implies 52.4% on each side, but de-vigged each side is really 50%. Every fair line and win probability on Dynatyze is computed from de-vigged consensus prices, never raw book odds.
How should I read prop hit rates?
A hit rate is how often a player has cleared a prop line over a sample — last 5, last 10, full season, or against a specific matchup profile. Raw hit rates mislead when the line has moved, so Dynatyze re-checks each historical game against the number the books are posting tonight and pairs the rate with minutes, role, and matchup context. A 70% hit rate against a stale line is trivia; a 70% rate against the current number is a signal.
What is Kelly staking?
The Kelly criterion sizes a bet in proportion to its edge and its odds: stronger proven edges earn larger stakes, marginal ones earn slivers. Full Kelly assumes your win probability is exact, which it never is, so the unit sizes shown on Dynatyze are fractional Kelly — a deliberate cut that protects the bankroll from model error while still scaling into the strongest edges.
What do sharp money and reverse line movement mean?
Tickets count how many people bet a side; money counts how much was staked. When 31% of tickets carry 78% of the money, a few large bettors are loading one side. Reverse line movement is the confirmation: the line moves against the ticket majority because the books respect the size, not the crowd. Dynatyze flags both, plus steam — synchronized line moves across many books inside a few minutes.
Why grade picks against the closing line?
Closing line value (CLV) measures whether you beat the market's final, sharpest price. Win-loss records swing on variance for months, but consistently beating the close is the most reliable predictor of long-term profit — it's the statistic sportsbooks themselves use to identify winning customers. Every Dynatyze pick is graded against the close in public, wins and losses alike.
How much does Dynatyze Betting cost?
The free tier seats you at the desk with a limited set of graded edges each night plus the live board. Pro is $24.99 per month and opens the whole wall — the full prop screener, sharp feed, arbitrage radar, DFS scanner, and the complete graded ledger. You must be 21+ to bet, and all betting happens at the sportsbooks, never on Dynatyze.
