Trade calculators
NFL
The Dynatyze dynasty trade calculator grades any NFL trade — Superflex, 1QB or 2QB, PPR, half-PPR or standard, TE premium and rookie picks — by adding up each side's dynasty value on the 0-9999 scale and grading the gap from A to F. It trades on the same values the NFL dynasty rankings publish.
NBA
The Dynatyze NBA trade calculator grades any fantasy basketball trade — dynasty, keeper or redraft, category or points scoring, with draft picks — by adding up each side's value on the 0-9999 scale and grading the gap from A to F. It trades on the same dynasty values the NBA dynasty rankings publish.
MLB
The Dynatyze MLB trade calculator is a fantasy baseball trade analyzer for dynasty, keeper and redraft leagues: it adds up each side's value on the 0-9999 scale — major leaguers, prospects, draft picks and FAAB dollars alike — and grades the gap from A to F. It trades on the same dynasty values the MLB dynasty rankings publish.
Rankings and draft tools
NBA Pick Rankings
Every rookie pick of the next three drafts is priced on the 0-9999 dynasty scale from its slot, its class strength and how many years out it is, then ranked among live dynasty player values. A protected pick is weighted by the lottery odds that it conveys, and nothing else is computed in your browser.
NBA Rookie & Prospect Rankings
Each row's number is his college box plus-minus, painted against his own draft class, and the class strength is measured against 19 seasons of college history. College prospects carry no price history yet, so the rows draw no line.
Devy Stash Score
The score blends devy market pedigree (45%), draft eligibility (20%), college fantasy production (20%) and the Campus-to-Canton comp score (15%). A part with no real data sits out and the other weights renormalize.
The CFF Draft Kit
A sleeper or fade chip means the market is at least two full rounds (24 picks) off our board, with rounds counted for 12-team rooms. The draft position is a dated market read, and the date it was taken prints with the board.
College Football Experts
Each expert's campus or devy boards are published and versioned, so you can read them list by list. Their published boards feed the CFB expert consensus.
Betting tools
What is a prop screener?
A player-prop screener filters every player proposition on the slate — points, rebounds, assists, strikeouts, and combos — by market, line, book, and model edge, so you can find mispriced props instead of scrolling a book's app one player at a time.
How should I read prop hit rates?
A prop hit rate is how often a player has cleared a given line over a sample — last 5, last 10, the full season, or a specific matchup profile. It only means something when it is measured against the line the books are posting right now.
Which book moved first?
This page lists every line a sportsbook moved in the window, graded from stored prices: which books moved a market the same way, which one moved first, and how many minutes later the others followed. It reads prices only — it cannot see who placed a bet or how much was wagered.
What is arbitrage betting?
Arbitrage betting is backing every outcome of a market at different sportsbooks whose prices, taken together, guarantee a small profit no matter who wins. It exists because books disagree, and the disagreement occasionally overshoots the vig.
What is a middle bet?
A middle is a pair of bets on overlapping lines — an Over at a low number and an Under at a higher one — that returns a locked baseline either way and a jackpot if the final result lands in the gap between them. It is a low-cost lottery, not a guaranteed win.
How does a correlation-aware parlay builder work?
A correlation-aware parlay builder prices a multi-leg bet using the real relationship between its legs rather than pretending they are independent — because legs from the same game rise and fall together, which books rarely price fairly.
What is prop correlation?
Prop correlation is the degree to which two props move together — a pitcher's strikeouts and the opposing team's total, or a quarterback's passing yards and his receiver's receptions — and it is the hidden engine behind fairly priced parlays.
What are betting projections?
Betting projections are model estimates of a player's stat line for a game, compared side by side against the sportsbook line so you can see where the model and the market disagree — the disagreement is the edge.
What is defense vs. position (DvP)?
Defense vs. position measures how much of each stat a defense concedes to opponents at a given position — points, rebounds, assists, or threes to guards, forwards, and centers. It is matchup context for pricing player props.
What are no-vig (fair) odds?
No-vig odds are a market's prices with the sportsbook's margin stripped out, so the implied probabilities sum to exactly 100% — the market's honest opinion of the outcome, and the baseline every edge is measured against.
How do you calculate a bet's expected value?
A bet's expected value is EV% = (fair probability × decimal odds − 1) × 100 — positive when the price pays more than the outcome's true chance demands, negative when it pays less.
How does the Kelly criterion size a bet?
The Kelly criterion stakes a fixed fraction of bankroll equal to (b·p − q)/b — where b is the net decimal payout, p the fair win probability, and q = 1 − p — the mathematically optimal size for long-run bankroll growth.
The betting education library explains the concepts behind these tools.
