LineRaptor FAQ
Understand the product, the math, the tracking process, and what LineRaptor does not do before using an alert.
Getting started
What is LineRaptor?+
LineRaptor is a beginner-friendly positive-EV tracking and odds analytics platform. It highlights potential market outliers, explains the pricing math, and paper-tracks what happens next.
Is LineRaptor a picks service?+
No. LineRaptor does not predict winners or sell picks. It flags prices that appear favorable relative to a fair reference estimate and records them transparently.
Does LineRaptor place bets for me?+
No. LineRaptor never places bets, connects to sportsbook accounts, or asks for sportsbook credentials.
Is LineRaptor for beginners?+
Yes. The product is designed to make EV, edge, implied probability, and closing-line value easier to understand without requiring a professional betting terminal.
Is LineRaptor free?+
LineRaptor is currently in beta. Future low-cost subscription pricing is planned, but beta access and final subscription details may change.
Why is LineRaptor expected to cost less than larger tools?+
It focuses on clear alerts, education, personalization, and paper tracking instead of trying to replicate every feature in a professional betting terminal.
The numbers
What does positive EV mean?+
Positive expected value means a price may return more than it costs on average over many similar opportunities, assuming the fair probability estimate is accurate. It does not guarantee that an individual bet wins.
What is implied probability?+
Implied probability converts sportsbook odds into the win probability represented by that price. For example, +150 American odds imply a 40% probability before adjusting for sportsbook margin.
What is no-vig fair probability?+
Sportsbook prices include margin, or vig. A no-vig probability removes the reference market's margin so all outcomes add to 100%, producing a cleaner fair-value estimate.
What is edge?+
Edge is the difference between LineRaptor's estimated fair probability and the probability implied by the offered sportsbook odds.
What does EV per unit mean?+
It estimates the theoretical long-term value of risking 1 betting unit at the offered price if the fair probability estimate is accurate. It is not a projected profit for one bet.
What is CLV?+
Closing-line value measures how the market moved after an alert. LineRaptor compares opening and closing implied probability; positive CLV generally means the alert beat the closing price.
Why does closing-line value matter?+
Results are noisy in small samples. Consistently beating the closing line can be an earlier signal that alerts found useful prices, although CLV alone does not prove profitability.
Does positive EV guarantee profit?+
No. Positive EV is a long-term estimate. Variance, imperfect fair probabilities, changing markets, and data quality all affect actual results.
Why can a good opportunity still lose?+
A favorable price changes expected value, not the final event outcome. Underdogs still lose often, and even high-probability outcomes sometimes fail.
Why do odds move after an alert?+
Sportsbooks update prices as new bets, information, and market changes arrive. An alert may improve, disappear, or become stale quickly.
Tracking and alerts
What does paper-tracked mean?+
LineRaptor records each qualified alert as if 1 unit were risked, without placing a real bet. This creates a consistent research history.
Why does LineRaptor track every alert?+
Complete tracking reduces cherry-picking. Opening price, closing movement, result, and paper profit or loss can all be reviewed later.
How are results graded?+
The VM score grader checks completed events, applies the correct moneyline, spread, or total result, and records a win, loss, or push.
What is stale risk?+
Stale risk warns that an offered price may be older, moving quickly, or less reliable. Always verify that a price is still available.
Why might an alert disappear before I can act?+
Odds can move, markets can close, or an opportunity may no longer pass your filters. LineRaptor does not control sportsbook availability.
Can I choose which books I use?+
Yes. Alert Settings lets you select the supported US sportsbooks available to you.
Which sportsbooks are in the default feed?+
LineRaptor's default beta feed focuses on supported U.S.-facing sportsbook prices such as DraftKings, FanDuel, BetMGM, Caesars, BetRivers, ESPN BET, and Fanatics. Offshore or unsupported books are hidden from normal alerts and consensus calculations unless a future advanced/internal mode explicitly enables them.
Can I filter by sport or market?+
Yes. Account settings control your coverage, and Live Alerts also has temporary sport, market, and sportsbook filters.
How do Telegram alerts work?+
Connect Telegram with a one-time code, then LineRaptor can send qualifying alerts that match your saved sports, markets, books, edge, EV, and quality preferences.
Do I need Telegram?+
No. Telegram is optional. The web dashboard remains available for live alerts, results, settings, and performance.
Trust and responsible use
Does LineRaptor guarantee profit?+
No. LineRaptor makes no profit guarantee. Positive EV and CLV are analytical estimates, and losses are always possible.
Is this financial advice?+
No. LineRaptor provides sports-odds analytics for education and research. Users are responsible for their own decisions.
Is my data private?+
Account data is protected through Supabase authentication and row-level security. Backend server credentials are never exposed to the browser.
Are sportsbook accounts connected?+
No. LineRaptor has no sportsbook account-linking feature.
Does LineRaptor use my sportsbook login?+
No. LineRaptor never requests, stores, or uses sportsbook login credentials.
Can LineRaptor bet automatically?+
No. There is no automatic betting functionality.
How should beginners use LineRaptor responsibly?+
Start with paper tracking, learn the terminology, verify every displayed price, use conservative limits, and never risk money you cannot afford to lose.
